Le Recensement des Oiseaux de Noël

Le Recensement des oiseaux de Noël, qui a vu le jour en 1900, est le plus ancien programme de science citoyenne d’Amérique du Nord. Il regroupe des participants dans plus de 2000 localités dans l’ensemble de l’hémisphère occidental.

 

Les renseignements recueillis par les milliers de participants bénévoles constituent un des plus importants ensembles de données d’inventaire faunique dans le monde. Des biologistes de la conservation et des naturalistes utilisent quotidiennement ces données pour évaluer les tendances des populations et la répartition des oiseaux.

Chaque recensement se déroule en une journée entre le 14 décembre et le 5 janvier. Il est réalisé dans un cercle de 24 kilomètres de diamètre, toujours le même d’une année à l’autre. Il se tient ordinairement en groupe à l’échelle locale, souvent par un club d’ornithologues amateurs ou de naturalistes.

Il est facile de participer!

  1. Trouvez un cercle de recensement près de chez vous et cliquez dessus pour connaître les coordonnées de la personne chargée de la compilation des données.
  2. Communiquez avec cette personne pour savoir comment participer.
  3. Comptez les oiseaux à la date de dénombrement fixée pour votre cercle, entre le 14 décembre et le 5 janvier. Vous pouvez même le faire depuis le confort de votre foyer!

 

Vous pouvez aider à faire le suivi et à assurer la conservation des oiseaux d’Amérique du Nord. Pour participer au Recensement des oiseaux de Noël, trouvez un cercle près de chez vous et communiquez avec le compilateur du cercle. Vous devrez être prêt(e) à réserver une partie ou la totalité de la journée prévue du recensement pour observer les oiseaux sur le terrain ou à une ou des mangeoires dans les limites du cercle. Les observateurs sur le terrain couvrent une partie de leur cercle seuls ou en petit groupe; ils comptent tous les oiseaux qu’ils voient ou entendent. Certains participants comptent les oiseaux à leur(s) mangeoire(s) pendant une partie de la journée.

Résumé du 120e recensement des oiseaux de Noël, 2020-2021

sommaire pour le Canada

Par Yousif Attia, coordonnateur – Recensement des oiseaux de Noël, Oiseaux Canada

Pendant la 121e saison du Recensement des Oiseaux de Noël (RON) au Canada, des données nous sont provenues de 450 cercles de recensement, soit 19 de moins que la saison précédente. Un cercle a refait naissance à Saint-Pierre-et-Miquelon, après un hiatus de deux ans. Dans beaucoup de cas, aucun recensement n’a eu lieu en raison des restrictions imposées par la COVID‑19, mais les activités ont pu se dérouler dans la plupart des cercles de recensement, car des mesures de sécurité supplémentaires y ont été prises. Quatorze nouveaux cercles ont été enregistrés en 2020-2021 : Lacombe (AB), Ladysmith (BC), Hartland, Mount Carleton, New Jersey-Neguac, Nictau-Riley Brook, Perth-Andover, Plaster Rock, Red Bank-Sunny Corner, Southeast Upsalquitch, Springfield et Sussex (NB), et Val Marie (SK). Les cercles du Nouveau‑Brunswick existaient préalablement, mais n’avaient pas encore été enregistrés officiellement. Enfin, deux cercles déjà enregistrés qui étaient inactifs ont été réactivés, soit ceux de St. Andrews (NB) et de Torch Valley (SK).

Au total, 10 741 participants sur le terrain dans la nature et 4586 participants à des sites de mangeoires ont signalé un peu moins de 3,5 millions d’oiseaux de 284 espèces (tableau 1). C’est à Edmonton, en Alberta, qu’on a enregistré le plus grand nombre de participants (473) le jour officiel du RON; suivaient Victoria, en Colombie-Britannique, avec 319 et Calgary, en Alberta, avec 287. Les cinq cercles qui viennent en tête de liste quant au nombre d’espèces signalées sont les suivants : Victoria (143 espèces) et Ladner (128), en Colombie-Britannique; Halifax‑Dartmouth, en Nouvelle-Écosse (127); Parksville-Qualicum Beach, en Colombie-Britannique (123); et White Rock-Surrey-Langley, également en Colombie-Britannique (123).

La région atlantique (Nouveau-Brunswick, Terre-Neuve-et-Labrador, Nouvelle-Écosse, Île-du-Prince-Édouard et Saint-Pierre-et-Miquelon) a bénéficié d’un automne relativement doux, suivi cependant d’une parfaite tempête de froid et de neige qui a concentré les oiseaux attardés. Le Québec est reconnu pour ses hivers froids mais, cette année-là, la première moitié de décembre a été l’une des plus douces jamais enregistrées. Même les provinces des Prairies ont signalé du temps doux et des conditions de recensement agréables pour au moins la première partie de la saison. Sans surprise, c’est dans le cercle le plus au nord, à Arctic Bay, au Nunavut, qu’on a enregistré le temps le plus froid pour le jour du 121e RON : la température a été de -37 oC pendant toute la durée du recensement.

Points saillants par région

Le tableau 1 présente un sommaire des statistiques des recensements pour l’ensemble des provinces et des territoires.

Voici la liste des 10 espèces les plus abondantes – en nombre d’individus signalés – dans l’ensemble des cercles de recensement du Canada pendant le 121e RON, dans l’ordre descendant : Bernache du Canada, Corneille d’Amérique, Étourneau sansonnet, Canard colvert, Mésange à tête noire, Moineau domestique, Oie des neiges, Tarin des pins, Pigeon biset (forme domestique) et Sizerin flammé. Le Grand Corbeau était l’espèce la plus répandue, détectée dans plus de cercles que toute autre espèce.

Une nouvelle espèce s’est ajoutée à la liste canadienne de tous les temps, qui compte maintenant 439 espèces, pendant la semaine du 121e recensement; il s’agit du Fuligule milouin (une femelle). Pour la quatrième année de suite, une Oie à bec court a fait son apparition à St. Johns, à Terre-Neuve-et-Labrador, le jour officiel du recensement. L’augmentation constante du nombre de Petites Buses dans la région est digne de mention, tout comme la présence de Tyrannus sp. (à ventre jaune) (Tyran mélancolique/de l’Ouest/de Couch) à Lunenberg et d’un Troglodyte des rochers à Halifax-Dartmouth, en Nouvelle-Écosse. L’irruption de Fringillidés qui s’est produite sur l’ensemble du continent s’est manifestée dans la région atlantique par l’augmentation du nombre de Sizerins flammés, de Durbecs des sapins et de Gros-becs errants. La même irruption s’est produite au Québec et en Ontario, où l’on a enregistré une hausse du nombre d’individus d’espèces venant du nord, telles que le Jaseur boréal et la Pie-grièche boréale. On a rapporté deux raretés notables à Otterburn Park, au Québec : l’Oie à bec court et l’Oriole de Bullock. En Ontario, un mâle de l’Oriole jaune-verdâtre, observé à Hanover-Walkerton, est un ajout coloré à la liste des espèces dignes d’intérêt dans cette province. À Pinawa, au Manitoba, une mangeoire a reçu la visite d’un Moqueur roux ainsi que d’une des trois Grives à collier signalées dans cette province. Les Laridés sont historiquement rares ou absents dans les prairies pendant les RON; c’est pourquoi les 32 Goélands argentés repérés au barrage de Gardiner témoignent du temps plus doux qui a précédé la saison. Comme dans l’Est, le nombre d’individus participant à l’irruption des Fringillidés dans le centre du pays était jusqu’à trois fois plus élevé que l’année précédente. En Alberta, la Grive à dos olive observée à Calgary était notable et une première en hiver. La diversité des Fringillidés qui ont fait irruption en 2020-2021 à l’ouest de la ligne de partage des eaux n’était pas aussi spectaculaire que plus à l’est; néanmoins, le Tarin des pins était la deuxième espèce la plus abondante en Colombie-Britannique. Parmi les nombreuses raretés qui se trouvaient dans cette province, le Fuligule milouin détecté pendant la semaine du recensement à Parksville-Qualicum Beach et le Moucherolle noir vu à Victoria étaient les plus remarquables.

Pendant le 121e RON, la diversité des espèces a augmenté dans tous les cercles de recensement par rapport à l’année précédente, sauf à Terre-Neuve-et-Labrador et au Yukon, où elle a diminué, et dans les Territoires du Nord-Ouest, où elle est demeurée stable. C’est en Colombie-Britannique qu’on a enregistré la plus grande diversité (224 espèces), puis en Ontario (177), en Nouvelle-Écosse (175), au Québec (146) et au Nouveau-Brunswick (142). Les sommaires régionaux détaillés du 121e RON seront présentés sur le site Web d’Audubon, où l’on peut d’ores et déjà trouver les données historiques ou de l’année courante par cercle de recensement ou par espèce.

Des remerciements particuliers sont adressés aux compilateurs, qui passent des heures à recruter des participants et à les répartir et les soutenir sur le terrain, ainsi qu’à réunir et entrer les données. Un grand merci également aux réviseurs régionaux, qui effectuent une validation minutieuse de toutes les données du RON chaque année.

2020/21 Canadian High Counts Article (en anglais)

 

During the 121st Christmas Bird Count (CBC) in Canada, counts reported 284 species, a decrease of five species from last year. Seven additional species, Common Pochard, Cattle Egret, Barn Swallow, American Redstart, Black-throated Green Warbler, Western Tanager, and Indigo Bunting were recorded only during count week. A yellow-bellied kingbird species (i.e., Western/Tropical/Couch’s), although not identified to species, is still a very rare bird on Canadian CBCs. The count week Common Pochard is new for the all-time Canadian species list, which now sits at 439 species.

Each of Canada’s ten provinces and all three territories recorded at least one species high count during the 121st CBC season. Counts in British Columbia (BC) recorded the most species high counts (153), followed by Ontario (92) and Nova Scotia (42). Victoria, BC, was the circle to achieve the most species high counts (43), followed by Ladner, BC (24), Long Point, ON (13), St. Johns, NL (11), and Toronto, ON (9). Twenty of the high counts during the 121st CBC season represent new all-time Canadian highs (numbers boldfaced). Fifty-two high counts are high counts not only for Canada, but all of North America (numbers italicized). Unestablished exotics and hybrids are excluded from this list.

All-time Canadian High Counts (2020 Update; en anglais)

 

This is a summary of the highest counts reported for individual species and forms in Canada since the Christmas Bird Count (CBC) began in 1900. A total of 438 species have been reported on Count Days during that period, which is an increase of 18 species since Richard Cannings summarized Canadian CBCs ten years ago. British Columbia CBCs recorded the most species high counts (187), followed by Ontario (115), Nova Scotia (61), Alberta, (18), and Newfoundland and Labrador (17).

There are seven species and one form only found during Count Week (cw): Tundra Bean-Goose, Solitary Sandpiper, Spotted Redshank, Laysan Albatross, Manx Shearwater, Magnificent Frigatebird, Red-tailed (Krider’s) Hawk, and Cassin’s Vireo.

Le 121e Recensement des oiseaux de Noël (RON) a été très fructueux au Québec cette année. En effet, il y a 9 espèces de plus que la moyenne des 6 derniers recensements. Au total, 145 espèces plus quatre espèces d’origine domestique (Oie domestique, Canard malard d’origine domestique, Faisan de Colchide et Perdrix Choukar) ont été observées le jour du recensement. Ce total se divise par 54 espèces aquatiques (37 % de toutes les espèces), 21 de rapaces (diurnes et nocturnes; 15 %) et 70 d’oiseaux terrestres (gélinottes, pics, passereaux;  48 %). Les températures de novembre et de décembre ont été au-dessus de la moyenne mensuelle, classant décembre du 12e mois le plus doux en cent ans au Québec. Ceci a pu favoriser le maintien de certaines espèces migratrices. Toutefois, les nuits froides du 15 au 19 décembre dans plusieurs régions ont causé une couverture de glace de plusieurs plans d’eau; sans cela, les décomptes auraient pu être plus élevés. Enfin, la température a été favorable pour plusieurs recensements, contrairement à l’an passé, où il pleuvait sur le sud du Québec le 14 décembre 2019, jour important de recensement.

Trente-sept recensements ont eu lieu au Québec, ce qui est en deçà de la moyenne 42 des dernières années. Quelques recensements ont été annulés en raison de la pandémie. Les recensements se sont tenus du 14 décembre au 4 janvier. Le jour le plus populaire fut le 19 décembre avec 17 recensements, suivi du 20 décembre avec 5. Un total de 1 162 personnes a participé aux recensements, une légère baisse comparativement aux années précédentes, expliquée par la baisse du nombre de recensement. Le RON de Québec a totalisé le plus grand nombre d’observateurs (165), suivi par Lennoxville (84), Montréal (70) et Hudson (68).

Les espèces d’oiseaux observés dans les recensements québécois ont totalisé un impressionnant total de 380 687 individus (environ 177 000 de plus que l’an passé). Saint-Jean-sur-Richelieu s’est encore classé premier avec 91 157 oiseaux, essentiellement grâce à la présence de l’Oie des neiges (9 159) et de la Corneille d’Amérique (72 000), suivi d’Otterburn Park (83 466) avec 54 046 Oies des neiges, et de Baie-Missisquoi avec 29 272 oiseaux. Montréal (15 665), Québec (15 217), Granby (14 116), St-Timothée (12 996), Longueuil (12 152) et Lennoxville (11 718) sont les autres recensements à dépasser le cap des 10 000 oiseaux. Le RON de Québec a eu le plus grand nombre d’espèces (84), suivi d’Otterburn Park (79), Montréal (78), Longueuil (69) et Hudson (63).

Six espèces ont été rapportées dans tous les territoires de recensement : le Pigeon biset, le Pic mineur, la Corneille d’Amérique, le Grand Corbeau, le Geai-bleu et la Mésange à tête noire. Le Pic chevelu, la Sitelle à poitrine rousse et le Durbec des sapins ont été notés dans 36 RON. Le nombre total d’individus recensés dans les 37 RON, qui dépasse les 10 000 sont : la Corneille d’Amérique avec 90 981 (dont la majorité à Saint-Jean-sur-Richelieu et à Granby avec 9 000), l’Oie des neiges avec 82 190, la Bernache du Canada (38 585), la Mésange à tête noire (17 329), l’Étourneau sansonnet (16 969), le Sizerin flammé (15 977), le Pigeon biset (15 725) et le Canard colvert (13 498). Il est intéressant de mentionner la différence d’abondance entre 2019-2020 et 2020-2021 pour le Jaseur boréal (7 versus 4 413), le Durbec des sapins (140 versus 1758), le Gros-bec errant (342 versus 3 002) et le Sizerin flammée (94 versus 15 977). Mentionnons que la Pie-grièche boréale a connu une bonne année avec 62 individus vus dans 25 RON.

Chez les espèces menacées ou vulnérables ou susceptibles d’être désignées comme tel, notons un Grèbe esclavon (Percé), 17 Arlequin plongeur (Forillon, Montréal, Parc Aiguebelle, Percé) et 1 837 Garrots d’Islande (répartis dans 8 RON). Le Pygargue à tête blanche a totalisé 127 individus répartis dans 30 RON, tandis que le Faucon pèlerin (13) a été rapporté dans 6 RON, et le Hibou des marais (10) dans Longueuil et  Otterburn Park. L’Aigle royal et le Quiscale rouilleux n’ont pas été rapportés cette année.

Au chapitre des espèces rares (en général ou pour la saison), notons les espèces suivantes observées le jour du recensement, dans un recensement québécois cette année : Oie à bec court (Otterburn Park), Cygne siffleur (Îles-de-la-Madeleine), Fuligule à tête rouge (St-Timothée), Urubu noir (Lascelles), Guillemot de Brünnich (Forillon), Mouette rieuse (Îles-de-la-Madeleine), Pic maculé (Otterburn Park), Troglodyte des marais (Montréal), Moqueur chat (Québec), Moqueur roux (Georgeville), Paruline bleue (Beauce), Oriole de Bullock (Otterburn Park).

Enfin, mentionnons des espèces peu souvent rapportées lors des recensements (jour du recensement) : Oie rieuse (Otterburn Park), Eider à tête grise (Tadoussac), Bécasseau violet (Îles-de-la-Madeleine), Mergule nain (Forillon et Îles-de-la-Madeleine) Petit Pingouin (Percé), Épervière boréale (Duhamel), Pic tridactyle (Chicoutimi-Jonquière), Solitaire de Townsend (Lennoxville), Moqueur polyglotte (Longueuil), Paruline à croupion jaune (Îles-de-la-Madeleine),  Bruant des prés (Cowansville) et le Bruant Fauve (Montréal).

Alberta

By Daniel Arndt

Despite the challenges of organizing, running, and compiling counts during a pandemic, 54 Christmas Bird Counts submitted data during the 121st (2020-2021) season in Alberta. December 20 was the most popular count day (17), followed by December 19 (12), and December 27 (5). A total of 229,522 individual birds of 124 species were tallied by 1,309 field counters and 845 feeder counters, an increase in both from the previous year, with 140 new feeder watchers participating. Edmonton had the most field counters (222), while Calgary led the province with party effort and party miles. Participants on the Devon-Calmar CBC put in the most nocturnal effort. Edmonton by far had the most feeder counters (251), followed by Calgary (157).

Calgary was the top count with 69 species on count day, up from 64 species the year previous. Three species or forms were only detected during Count Week, including: Greater White-fronted Goose (Lethbridge), Snow Goose (Calgary), Red-breasted Merganser (Banff-Canmore). The top 10 most abundant species in Alberta, in order of most to least abundant were: Canada Goose, House Sparrow, Mallard, Black-capped Chickadee, Bohemian Waxwing, Rock Pigeon (Feral Pigeon), Black-billed Magpie, Common Raven, Common Redpoll, and Snow Bunting. Black-billed Magpie and Common Raven were the only species reported on all counts; Blue Jay and Black-capped Chickadee were reported for all but three circles.

Weather conditions throughout Alberta were textbook, with lower temperatures and deeper snows reported at higher latitudes, while higher temperatures and associated higher winds recorded in the central and southern regions of the province. Peace River recorded the coldest low temperature on count day with -27 degrees Celsius, while Lethbridge was the warmest at 9 degrees Celsius. A heavy snowfall early in the new year provided Cochrane with the greatest maximum snow depth (50 cm), while the highest maximum wind speed was, unsurprisingly, reported for Lethbridge (75km/hr).

Species and notes

Canada Goose (75,728) was the most abundant waterfowl species reported, down from the previous year, followed by Mallard (15,908), Common Goldeneye (1,923), Bufflehead (228), and Common Merganser (99), all of which are increases from the previous count year. Lethbridge reported the highest count of Canada Goose (34,576) in Alberta, and Cackling Goose was reported again for Calgary and Lethbridge; participants are reminded to try to obtain photos of this species when observed. Six Trumpeter Swans were reported, with 4 in the Brule count circle, and 2 in Waterton Lakes N.P., and two Tundra Swans were observed, one in the High River count, and the second at Wabumun Lake. Other notable waterfowl include a Wood Duck and a Long-tailed Duck in Calgary, and an overwintering Ruddy Duck in Medicine Hat. Sharp-tailed Grouse were recorded in small numbers throughout their range, with the highest numbers reported for Dinosaur Provincial Park (67) and Manyberries (40). Ring-necked Pheasant numbers are much more scarce than last year, with the highest number also reported in Manyberries (26). Six counts recorded Spruce Grouse, with 3 each reported for Athabasca and Jarvie. The only grebe species reported were 4 Horned Grebes reported for Waterton Lakes N.P., along with one Common Loon in that count circle. A second Common Loon was reported for Spruce View. One American White Pelican was recorded for High River, which was only the third record for the province, and one of only two recorded in Canada this year.

One Virginia Rail was reported in the Banff-Canmore count circle, a usual location for this species, while American Coot was reported on 5 counts: Calgary (3), Spruce View (4), Lethbridge (1), and Medicine Hat (12), with an additional record from Waterton Lakes N.P. during count week.

Three counts reported Killdeer, including Snake’s Head (2), Calgary (3), and Red Deer (1). Wilson’s Snipe numbers were up this year with 5 individuals reported in two counts in the Rockies, four individuals in the Banff-Canmore circle, and one in Jasper. Gull numbers rebounded, with one Glaucous Gull recorded on the Wabamun Lake count, and five white-headed gulls recorded in Medicine Hat. Mourning Dove numbers, following a drop after an unusually high year during the 116th, seem to be back on the rise.

For another year, Bald Eagle was the most abundant raptor (245) with a sharp increase in the number of  Rough-legged Hawk (119), but a decline in records for Northern Goshawk (23). Merlin (63) was the most abundant falcon, followed by Prairie Falcon (18), and Gyrfalcon (6), with Canadian high-counts for Prairie Falcon in Medicine Hat (4), and Gyrfalcon in Devon-Calmar (2). A lone American Kestrel was recorded at Medicine Hat for another year. Once again, all nine expected owl species were detected including Canadian high counts represented by fifteen Great Gray Owls at Cochrane Wildlife Reserve, and one Boreal Owl at Devon-Calmar, for the second year in a row. Great Horned Owl was the species most detected (82), followed Great Gray Owl (39), with a sharp decline in Snowy Owl from last year, with only 10 observations.

High counts for Canada were recorded for American Three-toed Woodpecker (10) at Banff-Canmore and Downy (430) and Pileated (86) at Edmonton. With 9 Belted Kingfishers in the province, this species remains stable to increasing trend during winters in Alberta.

The highest Canadian counts for Clark’s Nutcracker once again was recorded in Banff-Canmore (91) with Edmonton displacing Calgary as the high-count for Black-billed Magpie, with 3,447 observed. For the second year running, Mountain (332), Black-capped (3,691), and Boreal Chickadee (68) topped the Canadian records at Banff-Canmore, Edmonton, and Sheep River, respectively. Only a solitary Pacific Wren was reported in Alberta, with that record coming from Lethbridge.

A Swainson’s Thrush reported in Calgary was a high-count for Canada, as was a Brown Thrasher in Lac La Biche. One Mountain Bluebird was reported for Calgary, the first of that species reported during a Christmas Bird Count in Alberta.

After a few years of holding the North American records of both House Sparrow and Bohemian Waxwing, that title did not fall to Calgary, however the numbers were still impressive, with 6,999 and 859, respectively.

As per usual, Dark-eyed Juncos represented the sparrows with a large presence at 577, however White-throated Sparrow numbers jumped to 39. White-crowned Sparrow (8), Song Sparrow (5), and Harris’s Sparrow (3) made good showings, but the highlight of this family was a pair of Savannah Sparrows on the Blindline count. Red-winged, and Yellow-headed blackbirds were a notable absence this year, with only 4 Common Grackle, 1 Rusty, and 1 Brewer’s Blackbirds being reported, but Western Meadowlark were present in the highest numbers recorded in the province, from two count circles: Dinosaur Provincial Park (19), and Medicine Hat (2). Two Yellow-rumped Warblers were reported, one in Edmonton, and one in St. Albert, were noteworthy finds.

Finch numbers during the 121st Christmas Bird Count were respectable, but with a massive irruption in Eastern Canada of redpolls and grosbeaks, the 3,534 Pine Grosbeaks and 7,930 Common Redpolls were scattered throughout the province in numbers only slightly higher than average, but impressive nonetheless.

Atlantic Canada (NB, NL, NS, PE) (en anglais)

By Jared Clarke

The 121st Christmas Bird Count season was a bright spot in a tumultuous year throughout most of Atlantic Canada, as it was everywhere. With a pandemic turning the world upside down, people increasingly took solace and comfort in nature – especially birding. The fresh air, wonderful birds and great camaraderie of CBCs took on new meaning for many. A relatively mild fall with plenty of winds from the south and west led to an array of vagrants and displaced migrants hanging on into winter, while the sudden onset of cold and snow in some areas concentrated birds within count circles. All in all, it was a season to remember.

A total of 88 counts were completed in the Atlantic region this season; with 43 in New Brunswick, 32 in Nova Scotia, 10 in Newfoundland & Labrador and 3 in Prince Edward Island. The number is up significantly from previous years, mainly due to a concerted effort by dedicated birders at Nature New Brunswick to have more of their provincial results submitted online. Involvement was also up with well over 2100 participants, ~1450 of which put in 3915 hours in the field. The bird tally was somewhat above average with 196 species recorded throughout the region (including a few count week observations) – due in no small part to a good number of rare and lingering species throughout.

Despite being rare in North America, Pink-footed Goose was recorded for the fourth straight season with a long-staying individual in St. John’s (NL). Other locally rare or uncommon geese included a Greater White-fronted Goose in Pictou Harbour (NS), Cackling Goose in Moncton (NB) and several Snow Geese in NS & NB. A Tundra Swan was also among the highlights at Cape Sable Island (NS). The 52 Tufted Duck tallied in St. John’s (NL) was relatively low for the circle compared to recent years, and the only other individual for the region was at Antigonish (NS). A Redhead in Glace Bay (NS) and a Ruddy Duck at Halifax-Dartmouth (NS) were also regionally rare. A record high 16 Barrow’s Goldeneye in NF included a notable count of nine in the Stephenville area.

Shorebird diversity was down significantly from last season with a more typical six species recorded, mostly in NS.  Perhaps the most notable was a lingering Willet, recorded as the western race, at Broad Cove (NS). Purple Sandpipers were slightly below average with 99 in NS and 300 in NL. Killdeer, Black-bellied Plover, Sanderling and Dunlin rounded out the tally.

The elusive Gray Partridge put in a showing with 7 spotted on the PEI National Park count. This species has been extirpated from NS, but continues to keep a small yet firm foothold on the island. A total of 161 Wild Turkeys were recorded on five counts in NB, the bulk from St. Stephens (on the border with Maine) and nearby Mactaquac – the only established population in the region. Willow Ptarmigan were recorded in four different circles in NL, including five in Happy Valley-Goose Bay.

Diurnal raptors are always a highlight, and this year was no exception. A Black Vulture in Pictou Harbour (NS) was regionally rare, but showing up in the Maritimes with more frequency in recent years. A total of 157 Turkey Vultures were also spotted in the province, along with 28 in neighbouring NB. Bald Eagles continue to increase in the region, with 1908 individuals reported across all four provinces. The number of late and/or wintering Broad-winged Hawks in the region appears to be growing, with five reported in NS and another in NB this season. A Gyrfalcon seen during count week in Sackville (NB) was the only one this season and always an exciting find.

Not to be outshone, seven species of owl were reported throughout the region including 33 Great Horned, 28 Barred, 9 Northern Saw-whet, 21 Short-eared, and a single Long-eared. A Great Gray Owl in Stanley (NB) was very notable. It was another low year for Snowy Owl with just 4, while Boreal Owl was once again missed altogether. Woodpeckers put in a typical showing across the region, although a Red-Headed Woodpecker in Memramcook-Hillsborough (NB) was a local rarity and an American Three-toed Woodpecker in Bonne Bay (NL) is notable since it often goes unrecorded during the season.

A surprising five species of wren were recorded in the region this season, including an exceptionally out-of-range Rock Wren in Halifax-Dartmouth (NS) – perhaps the rarest bird recorded in the region this season. Carolina Wren has become expected in recent years and were recorded in a total of seven circles across NS & NB this year. Two Winter Wrens, two House Wrens and a single Marsh Wren round out the count.

Rare and lingering warblers are often a “prize” of the season in Atlantic Canada, and there was notable diversity this year. A total of twelve species were recorded, including good numbers of expected species such as Pine (47), Yellow-rumped (30) and Orange-crowned Warblers (14), along with Yellow-breasted Chat (11). Other warblers throughout the region included Palm (6), Common Yellowthroat (6), Wilson’s (2), Tennessee (2), Yellow (1), Black-and-White (1), Cape May (1) and American Redstart (1). The only lingering vireo was a single Blue-headed Vireo in Yarmouth, NS.

Other lingering birds of note in the region included a Sandhill Crane (NS), nine American Coots (NS & NL), two Eastern Towhee (NB & NS), 14 Hermit Thrush (NB, NS & NL), 15 Northern Mockingbirds (NS & NL), 64 Brown-headed Cowbirds (PEI) and 20 Baltimore Oriole (NB, NS & NL). Nearly 1800 Northern Cardinals were recorded across this region this season, including 2 in NL where they remain a rare visitor at any time of year.

Notable birds in the region at any season included a Common Gallinule (NL), Little Gull (NS), Townsend’s Solitaire (NS), Blue-grey Gnatcatcher (NS), Western Tanager (NS), Brown Thrasher (NB) and two Yellow-headed Blackbirds (NB & PEI). Locally uncommon sparrows also included a Lark Sparrow in Glace Bay (NS) and Clay-coloured Sparrow in Hillsborough (PEI). A “yellow-bellied” kingbird in Lunenberg (NS) was not identified to species but would certainly have been a rare record.

With finch irruptions being reported all over the continent this season, it is not surprising that numbers were all over the board in this region. Pine Grosbeak (1880), Common Redpoll (12,831) and Evening Grosbeak (9,935) were up significantly from last season and reflecting huge incursions seen into other parts of southern Canada and the northern United States. White-winged (1476) and Red Crossbills (195) showed more moderate increases, while Purple Finch (272) and Pine Siskin (694) were down from last year – perhaps as many had moved to points further south. American Goldfinch remained stable with 11,059 individuals recorded, indicating that they remain more or less resident throughout the region. House Finch continues to increase in NB & NS where a total of 219 were reported. House Sparrow numbers remained relatively stable at 1540, although anecdotally they continue to decline in many places.

British Columbia (en anglais)

By Yousif Attia

A total of 87 Christmas Bird Counts in British Columbia (BC) submitted data for the 121st (2020-21). Despite the COVID-19 pandemic, most counts were safely conducted taking precautionary measures and not holding in-person gatherings. One previously unregistered count, Ladysmith on Vancouver Island, was welcomed during the 121st. Sunday, December 20 was the day most counts took place (19), followed by Sunday, December 27 (17), and Saturday, December 19 (11). Victoria had the most counters in the field (265), followed by Galiano-North Saltspring (135), and Pender Islands (130). Parksville-Qualicum Beach had the most Feeder Counters (76), an increase compared the year previous (59), followed by Victoria (54) and Creston (29).

A total of 1,024,335 individual birds of 224 species were tallied by 2828 field counters and 719 feeder counters. Victoria was the top count with 143 species on count day, an increase of 8 species compared to last year. Seven species only detected during Count Week include: Common Pochard (Parksville-Qualicum Beach), Gray Partridge (Peachland), Cattle Egret (Cortes Island), Lesser Black-backed Gull (Vernon), Black-backed Woodpecker (100 Mile House, Cranbrook, Golden, Prince George, Rossland-Warfield), Barn Swallow (Victoria), and Common Yellowthroat (White Rock-Surrey-Langley). The top 10 most abundant species in BC, in order of most to least abundant were: Pine Siskin, Mallard, European Starling, Canada Goose, Dark-eyed Junco, American Wigeon, Glaucous-winged Gull, Dunlin, American Robin, and Snow Goose. Bald Eagle and Common Raven were the only species reported on all counts.

Weather during counts in BC was mild in general. Fourteen circles reported precipitation during both the morning and afternoon on count day. Penticton enjoyed a count day high of 14 degrees Celsius while neighboring Peachland took place nine days later and reported the coldest low temperature on count day (-11 Celsius). Five counts (Big White, Golden, Nelson, Smithers, and Yoho N.P.) reported maximum snow depths of one meter or more, with Nelson again on top as the snowiest circle.

Species and notes

Mallard (79,416) was the most abundant waterfowl species reported in BC, followed by Canada Goose (60,650), American Wigeon (54,575), Snow Goose (21,309), and Bufflehead (14,323). Chilliwack set a Canadian all time high record for Cackling Goose (6153), a species that seem to be observed in increasing numbers during winter in the Fraser Valley. The count week female Common Pochard at Parsksville-Qualicum Beach was new for the Canadian Species list. Remarkably, a male was at Victoria circle up to only one month prior. Greater Masset was the only circle to report “Eurasian” Green-winged Teal, compared to two from as many circles last year.

Three Dusky Grouse at Penticton was a North American high count. Victoria, Sidney-South Saltspring, Comox, Cortes Island, Galiano North Saltspring, and Powell River had Canadian high counts of all the grebes. The most abundant grebe species was Horned (3063), followed by Red-necked (1496) and Western (1340).

A count week Cattle Egret at Cortes Island was the only noteworthy heron. Parskville-Qualicum Beach had the highest count for Pacific Loons (721) in North America. Common Murre was the most widely reported and abundant alcid (2849), closely followed by Ancient Murrelet (2668). One Cassin’s Auklet at Bamfield was the only one reported. Parksville-Qualicum Beach reported the highest number of Ancient Murrelets in North America. Sooke had the North American high count for Brandt’s Cormorant while Victoria again had the highest count of Pelagic Cormorant.

The only reported Whimbrel was at Deep Bay, and White Rock-Surrey-Langley set a count high of 9 Marbled Godwits. Ladner’s 33, 255 Dunlin were a high count for North America, a reminder of the importance of the Fraser Estuary for this species. Another North American high count was Surfbirds at Nanaimo. Penticton recorded the highest number of California Gulls in Canada, and also a new high for the count.

Penticton also reported the Canadian high count for Golden Eagles (9) while Terrace had the North American high count for Northern Goshawk (5). Bald Eagle (8146) was the most abundant species of raptor, followed by Red-tailed Hawk (1192), Cooper’s Hawk (294), Northern Harrier (221), and Sharp-shinned Hawk (186). Three circles reported “Harlan’s” Red-tailed Hawk in the province: Oliver-Osoyoos, Armstrong-Enderby, and Lake Country. A total of 425 owls of 10 species was in increase compared to 343 individuals of 11 species during the 120th. Surprisingly, Northern Pygmy-Owls (93) outnumbered Barred Owls (76) in BC, but that could have been due in part to the absence of Vancouver. No Snowy Owls were reported on count day or count week in BC.

Another year, and another record all-time high count for Anna’s Hummingbird (1,331) in Victoria as the species continues to increase elsewhere in the province. The only Rufous Hummingbird in BC was at Squamish. One Yellow-bellied Sapsucker was a pleasant surprise at Ladner while Black-backed Woodpecker was not detected on Count Day despite being recorded on Count Week by five circles. The only Prairie Falcon on Count Day in BC was at Oliver-Osoyoos and Pitt Meadows detected one for Count Week.

A Black Phoebe at Victoria might have been the rarest bird recorded on a Count Day. Western Scrub-Jays were at Squamish, Ladner, and Harrison River. A Northern Mockingbird was at Victoria on Count Day, while another was at Cranbrook for Count Week. A Count Week Barn Swallow was the only one swallow the province. Victoria had North American high counts for Chestnut-backed Chickadee, Brown Creeper, Pacific Wren, and Bewick’s Wren, which was also a new high count for the circle. Four out of the six Mountain Bluebirds in BC were at Vaseux Lake.

One Clay-coloured Sparrow at Comox was unusual and single Harris’s Sparrows were at Kelowna and Williams Lake. Victoria reported North American high counts for Fox Sparrow and Dark-eyed (Oregon) Junco. A Bullock’s Oriole stuck it out until Count Day at Comox and single Common Grackles were at Dawson Creek and Prince George. Notable warblers were one Count Week Common Yellowthroat at White Rock-Surrey-Langley, one Palm Warbler at Parksville-Qualicum Beach, and single Wilson’s Warblers at Chilliwack and Kelowna. Kelowna and Penticton both had single Lesser Goldfinches, but the most impressive finch highlight was the invasion of Pine Siskins in the province, the most counted bird of the 2020-21 CBC.

The 2020/21 Christmas Bird Count was perhaps most memorable for response to the coronavirus. Three counts were canceled for health and safety concerns, while most of the remainder imposed limits on participants. While this resulted in fewer hours of observation for many counts, a few fielded their usual number of field parties (although often reduced size of parties) and some had high totals of species, if not of individual birds.

Weather may have been somewhat of a factor in the counts—where mentioned, it was mostly pleasant. By my publication deadline, 15 counts had reported, with probably three more in the pipeline. Thank you to those compilers who reported their counts in a timely manner, as it makes this much easier to summarize. Because of reduced count effort, and the tardy count results the summary will be briefer than usual.

Winnipeg, as usual, led the species count at 49, nine higher than last year.

At publication deadline, the species total was 74 species and one hybrid on count day, with five additional species recorded as count week only (seen on at least one of the three days preceding or following the count, but missed on count day itself).

Some of the more unusual waterfowl species included an American Black Duck, three Buffleheads and a Common Merganser at Winnipeg, and single Common Goldeneyes at Pinawa & Winnipeg.

The Pas had the only Spruce Grouse, but found three of them.

A Great Blue Heron was at Winnipeg, a first for them.

A Sharp-shinned Hawk was recorded in count week at Portage la Prairie.

Winnipeg had the only Eastern Screech-Owls, a total of three. Snowy Owls were scarce, recorded on only two counts, with singles at Delta Marsh and Portage. A Barred Owl was found on count week at Winnipeg. Great Gray Owls were found on three counts, Dauphin (with two), Hodgson & Pinawa (with five). A Boreal Owl was found on count week at Riding Mountain.

Red-bellied Woodpeckers put on a strong showing, with four counts reporting them, including three at Winnipeg and singles at Balmoral, Morden and Portage.

Winnipeg had the only Merlins (with three) and a Gyrfalcon was seen at Hodgson.

A Carolina Wren was at a feeder in Winnipeg, and remained through much of the winter.

A Hermit Thrush was reported at Winnipeg. Varied Thrushes were seen on three counts, with singles at Delta Marsh, Pinawa and Winnipeg.

A Brown Thrasher was on the Pinawa CBC, frequenting the same feeder as the Varied Thrush.

Cedar Waxwings were a little more numerous than usual, and outnumbered Bohemians on a few counts, although the latter were more numerous overall.

An American Tree Sparrow was a count week record at The Pas. Other Sparrows included a Chipping Sparrow in Winnipeg, a White-crowned Sparrow at Gimli, a Song Sparrow at Delta Marsh and a Harris’s Sparrow in Winnipeg.

Purple Finches were all but absent, with a count week record at Winnipeg being the only one reported by my deadline.

Finally, at least one of the House x Eurasian Tree Sparrow hybrids continue to frequent the Winnipeg feeder where their parent resided for several years, and one was recorded on the count.

Thank you to all compilers and everyone who took part.  Maybe next year will see a more usual count.

Ontario (en anglais)

By Mike Burrell

The COVID-19 Pandemic loomed large over the 121st CBC season in Ontario, with 17 counts from year 120 not completed this year. We did have one new count (welcome, Dunnville!) and Presqu’ile was back after a missed year for a total of 111 counts, down from 126 last year and the lowest total since the 110 in count year 114.

The weather patterns leading up to count day always plays a big role. This year, the entire province saw above average temperatures right through November and December encouraging larger than normal (though, increasingly becoming the new normal!) waterbirds and other lingering species.

Count day weather was again pretty comfortable this year, with an average low of -5.7° C and high of -1.1° C; about the same as the last couple of years. 51 counts had temperatures that cracked the freezing mark this year, which, while lower than last year’s 73, is very high. Blenheim was the hotspot with a count day high of 6° C. Last year three counts cracked +10° C!. Eagle River took the award for coldest Ontario CBC with a low of -26° C although Atikokan had the coldest “high” temperature of just -19° C. Sixteen counts reported no snow at all, down from 20 in year 120 and 30 in year 119 (but up from year 118 when all counts had snow). 73 counts (down from 78 last year) had a maximum snow depth of 10 cm or less, so it was an easy year for walking. Hearst had the deepest snow, with a maximum snow depth of 80 cm, and 11 counts had 30 cm or more.

There were 3233 observers in the field this year, down significantly from the ~3700 of the last two years (not surprising given the drop in counts due to COVID) but still the sixth best. Conversely, more people opted to stay home and do feeder counts, resulting in a record 1437 feeder counters, more than 300 better than the previous high (1173) set last year. Added together field and feeder counters, the 4670 was the third highest total ever. All those observers put in a very impressive, and record 8505.25 party hours. Observers logged a very impressive 66,271 km on count days, well shy of the totals of the past five or six years. For the fifth straight year Ottawa-Gatineau led the pack with the most field observers, this year with 164. Kingston again led the way for feeder counters with a whopping 136.

A total of 172 species were reported from all counts, seven below last year’s 179 (which happens to also be the average from the last eight years) but considering the missing counts included seven from the most southern and species-rich part of the province the total is actually quite good. The total increased by six with the addition of count week species (American White Pelican, Great Egret, Glaucous-winged Gull, Northern Hawk Owl, Swainson’s Thrush, and Black-throated Green Warbler).

Blenheim and Long Point have basically alternated for most species over the last several years and this year Long Point took the cake with a whopping 114 species. Blenheim (111) and Hamilton (106) where the other two counts in the 100 species club this year. Five other counts cracked 90 species: Toronto (94), West Elgin (94), Woodhouse Township (94), Oshawa (91), and St. Clair NWA (90). That’s about as good as we ever do, with the eight counts at 80+ tying year 118 for the most. In general, most counts reported above-average species totals, with 86 counts equaling or beating their average from the past six years and the “average count” up four species. This was likely thanks to a combination of many lingering birds and an excellent finch year. London (80), Ottawa-Gatineau (77), and Brantford (74) led the way for inland counts. Nipigon-Red Rock led the way among northern Ontario counts with 41, one better than Thunder Bay’s 40 species. Long Point led the way with an incredible 30 (!) provincial highs, which speaks to the incredible numbers of lingering birds there this year. Toronto was no slouch with 15 provincial highs followed by six counts with seven provincial highs each.

A total of 1,156,357 individuals were counted, down about 115,000 from the five-year average, but given the counts that didn’t run this year have a five year average of just shy of 200,000, it was actually an above-average year, thanks to some big counts of waterbirds. The top five species this year were Canada Goose (195,564), American Crow (141,993), European Starling (110,364), Black-capped Chickadee (65,080), and Mallard (64,065); after a dip last year, Black-capped Chickadee was firmly back in the top five.

It really was an over-all better than average count year, but despite that some species were noticeably down. The following 27 species were recorded in numbers of 50% or less of their 20-year average: Snow Goose (71), Greater Scaup (16,832), Lesser Scaup (321), Ruddy Duck (324), Ring-necked Pheasant (35), Spruce Grouse (1), Horned Grebe (34), Red-necked Grebe (30), Black-crowned Night-Heron (6), American Coot (702), Bonaparte’s Gull (282), Ring-billed Gull (15,961), Glaucous Gull (73), Great Black-backed Gull (646), Long-eared Owl (25), American Three-toed Woodpecker (2), Black-backed Woodpecker (7), Northern Mockingbird (94), American Pipit (44), Lapland Longspur (40), Yellow-rumped Warbler (25), Fox Sparrow (11), Eastern Meadowlark (2), Rusty Blackbird (40), Common Grackle (565), Brown-headed Cowbird (2315), and Purple Finch (214). Many those can be explained by key counts that didn’t run this year because of COVID; for example, most gull numbers were down but Niagara Falls count didn’t run. Similarly, species like Yellow-rumped Warbler, Fox Sparrow and the blackbirds are often recorded in good numbers from the Essex County counts which didn’t run. Others, like Ring-necked Pheasant, Rusty Blackbird, and Eastern Meadowlark are part of long-term downward trends.

As is usually the case, there were some big misses this year: Brewer’s Blackbird was missed for the third straight year but only the fourth time in the past twenty. House Wren was also missed for only the fourth time in the past twenty years. Gray Partridge, Brant, Vesper Sparrow, Townsend’s Solitaire, Boreal Owl, Virginia Rail, and Varied Thrush were all missed but have been recorded on at least half of the past twenty counts.

Conversely, there were some excellent counts recorded, even with fewer counts reporting. The following 39 (!) species reported counts of 50% or more of their 20-year average: Greater White-fronted Goose (7), Cackling Goose (72), Mute Swan (3587), Trumpeter Swan (1068), Tundra Swan (24,065), Wood Duck (62), Northern Shoveler (371), Green-winged Teal (63), Redhead (22,053), White-winged Scoter (7,660), Black Scoter (95), Hooded Merganser (1,463), Sharp-tailed Grouse (142), Turkey Vulture (220), Bald Eagle (1561), Sandhill Crane (6011), Barred Owl (148), Short-eared Owl (94), Red-bellied Woodpecker (1752), Pileated Woodpecker (886), Merlin (119), Black-billed Magpie (163), Fish Crow (4), Red-breasted Nuthatch (5334), White-breasted Nuthatch (8673), Winter Wren (199), Marsh Wren (16), Carolina Wren (539), Gray Catbird (23), Bohemian Waxwing (15,456), Orange-crowned Warbler (7), Common Yellowthroat (16), Northern Parula (2), Northern Cardinal (11,813), Red-winged Blackbird (7,312), Red Crossbill (343), Common Redpoll (45,719), Hoary Redpoll (189), and Evening Grosbeak (3942).

Thirteen of those species also set new record highs: Mute Swan (3,587 vs 3,155), Trumpeter Swan (1,068 vs 849), Turkey Vulture (220 vs 189), Sandhill Crane (6,011 vs 3,717), Merlin (119 vs 102), Fish Crow (4 vs 1), Red-breasted Nuthatch (5,334 vs 4,805), White-breasted Nuthatch (8,673 vs 8,371), Carolina Wren (539 vs 521), Bohemian Waxwing (15,456 vs 15,074), Northern Parula (2 vs 1), Northern Cardinal (11,813 vs 10,702), Common Redpoll (45,719 vs 41,953), and Hoary Redpoll (189 vs 162). 

Those are long lists, but the species fall into a couple categories: first, many waterfowl were well above average. Next, we see some irruptive species (e.g. Barred Owl, the nuthatches, and finches) and finally are some species showing long-term increasing trends, plus a few other interesting one-offs. Some of those counts are especially impressive when one considers the key counts that were missing this year. Northern Cardinal jumps out as an interesting one as there was a huge irruption of them noticed in the north, but from the totals it is clear the entire province was seeing much more than usual. 

As mentioned above, irruptive species had big years in Ontario. Just the fact Bohemian Waxwing, Red-breasted Nuthatch, and both redpolls had record years makes that apparent but Evening Grosbeak and Red Crossbill both were also well up with both having their second-best year in the past twenty. Pine Grosbeak was about 20% above the twenty-year average and White-winged Crossbill had about the fifth best year of the past 20. Pine Siskin was about average and as is often the case in big finch flight years, Purple Finches pretty well completely vacated the province before the county period began. Northern Owls were a different story; Boreal Owl was missed; Northern Hawk Owl was only recorded during count week while Great Gray Owl had a decent year with 13 (highest since the 24 in count year 113). Northern Saw-whet Owl was slightly above average at 15.

There are always some exciting finds on CBCs, and this year was no exception. Two new species were added to the all-time Ontario CBC list: Scott’s Oriole (a male at a feeder in the Hanover-Walkerton circle) and a Glaucous-winged Gull during count week on the Sault Ste. Marie count). The latter represents the first record all-time for Ontario. Other good finds were two Norther Parulas on Peel-Halton (just one prior CBC record), two Fish Crows on both Peel-Halton and St. Catharines (just one prior CBC record), a Slaty-backed Gull on Toronto (two previous records), a Pacific Loon on Hamilton (seven previous records), Black Vulture on Sandbanks (just 11 prior CBC records), and a Palm Warbler on Toronto (12 previous records).

All in all, it was another excellent CBC season here in Ontario with highs, lows, and everything in between. Here’s to all the hard work the huge team of volunteers put in to making the count a success and for another good year in count year 122-it’s just around the corner!

Saskatchewan (en anglais)

By Guy Wapple

There were 39 Saskatchewan CBCs submitted, a decrease of five from last year. This was undoubtedly a result of the Covid-19 pandemic. In spite of that unpleasant situation, the counts went on, albeit with safety protocols in place.

The weather was generally cooperative throughout much of the count period. However, the first few days were chilly.

Gardiner Dam was done on Dec. 14th, hoping to take advantage of the mild fall conditions leading up to the CBC. Unfortunately, the observers had to deal with the coldest temperature the entire count period, at minus 20 C. The resulting fog from still-open Lake Diefenbaker, combined with light snow throughout the day made conditions challenging to say the least! The weather generally improved shortly afterwards, with fairly mild conditions prevailing during the remainder of count period. The warmest temperature was at Val Marie, which reached a balmy plus 6 C! Actually, the average minimum and maximum temperatures were the same as last year: -11 to -6 C, with wind speeds 9 to 20 km/h, vs 8 to 16 km/h. However, thanks to an early November blizzard, snow depth was considerably greater at 12 to 25 cms (5 to 12 cm in 2019).

For the first time since 2014, Saskatoon won the provincial crown for the most species at 44. Runner-up was Regina with 36 (plus 7 cw) species, with Gardiner Dam close behind at 35.   Balgonie (30 plus 2 cw), Clark’s Crossing (29 plus 4 cw), Prince Albert (28 plus 8 cw), Estevan (28 plus 7 cw), Fort Qu’Appelle (28 plus 6 cw), Moose Jay (26 plus 5 cw), Qu’Appelle (28 plus 3) were other counts breaking the magic 30 species mark. The average species result increased slightly from last year to 23 species on count day, with 25.5 found during count week.

Having said all that, this was still a fairly decent CBC year in Saskatchewan. There were 91 species recorded: 87 on Count Day, plus 4 seen only during count week: Barred Owl, Northern Hawk Owl, Townsend’s Solitaire and Cedar Waxwing. This was a very slight increase over 2019’s effort, which saw 90 species tallied. However, there were few rarities were recorded. An Eastern Bluebird seen on the Balgonie Count was the most unusual. The only previous Sask CBC record was two birds seen during count period at Craven in 1998. Other notable species included only the fifth Hermit Thrush (Saskatoon) and seventh Lincoln’s Sparrow (Harris).

Waterfowl were generally found in normal numbers, with the exception of two new provincial high counts established for Canada Geese and Common Goldeneye. There were 13 waterfowl species recorded, which was two less than last year. Cackling Goose were present at Estevan (75), Gardiner Dam (5) and Regina (1). Estevan established a new CBC record with an amazing total of 61.700 Canada Geese!!! This obliterated their previous high count of 33,775, which was established just last year! 8 Canadas at E.B. Campbell Dam, northeast of Nipawin were also notable. For the fourth consecutive year a male Wood Duck successfully overwintered at Regina! A male American Wigeon far to the north at E.B. Campbell, was new to the count and the only bird reported this year. A Northern Pintail was noted at Qu’Appelle Valley Dam (QVD). Gardiner Dam had the only Redhead, while Lesser Scaup were only seen at Gardiner and Saskatoon. Very rare in winter, the only Long-tailed Duck was at E.B. Campbell, which was also a new count species. Bufflehead sightings included 4 at Estevan and 5 at Gardiner. Common Goldeneye were reported from 9 areas, with an impressive 1032 at Saskatoon, a new SK CBC record. Hooded Mergansers were present at Gardiner (5, a record count record there) and Saskatoon (1), while Common Mergs were only seen at Gardiner (60) and Swift Current (1).

Sharp-tailed and Ruffed Grouse, along with Gray Partridge populations, remained relatively stable. Ring-necked Pheasants were recorded from six areas, including a decent total of 64 at Estevan. Spruce Grouse were noted at Candle Lake (3), as well as a well-documented bird far south of its normal range at Qu’Appelle!

Most raptor species were generally below normal numbers this winter. In a repeat of 2019, Northern Goshawks again staged a minor invasion of southern Saskie. They were recorded on 6 counts, with an additional ten cw observations. Sharp-shinned Hawks declined slightly to four localities, compared to six last year. Always a surprise during the winter months, single Red-tailed Hawks turned up at QVD and Swift Current, with cw birds at Craven and Moose Jaw. There were 16 Rough-legged Hawks on five counts (plus one cw), which was a substantial increase over last year’s total of three birds. Nine Golden Eagles were reported in three areas, including 6 on the Val Marie CBC. Bald Eagles rebounded nicely compared to last year with 89 birds on 21 counts, plus three during count week. As usual, Gardiner led the way with an impressive 51 birds.

Also as usual, the only American Coots seen were 20 on Boundary Reservoir, just south of Estevan. There was an amazing concentration of 32 Herring Gulls at Gardiner Dam, smashing the previous CBC record of 8 set here back in 1988. A single Glaucous Gull was among them. It was the 17th time this Arctic visitor has been recorded at Gardiner.

Eurasian Collared-Dove numbers appear to have peaked. There was a slight population decline compared to last year, with 347 individuals reported from 21 areas. After nada sightings last year, Mourning Doves turned up at Saltcoats (1) and Whitewood (2).

Great Horned Owl numbers declined slightly, with 13 at Morse leading the way. Snowy Owls visited elsewhere this CBC season, with only 30 birds reported from 11 areas, plus 4 during cw. A few “northern” owls also were noted. Single count week Northern Hawk Owls were found at Clark’s Crossing (well south of the Boreal Forest) and E.B. Campbell. There also were three cw Barred Owls, including one far south of the normal range at Biggar, where it appeared for the first time in 50 CBCs! Great Gray Owls staged a minor eruption into the parkland, with 9 birds on 4 counts, plus one during cw at Love. The latter location also reported the only Boreal Owl. Northern Saw-whets appeared on two CBCs.

Both Downy and Hairy Woodpecker numbers remained stable. American 3-toeds were seen in three areas, with a decent total of 6 at Prince Albert National Park (PANP). Black-backeds turned up on four CBCs, plus one during count week. PANP found six of them as well! Northern Flicker numbers were nearly double last total with 43 birds on 10 counts. Pileated numbers were up slightly from 2019, with 23 birds on ten counts, plus five more cw observations.

Merlin numbers doubled from last year to 16 birds from 7 localities. Always a treat, Gyrfalcons thrilled observers at Gardiner, Harris and Morse, as well as one cw report from Prince Albert. A Peregrine was at Qu’Appelle, while Prairie Falcons totalled four birds on three counts.

After good numbers the past three CBC seasons, Northern Shrike numbers dropped back to just 8 birds on 6 counts, with 5 reported during count week. Corvid numbers remained stable, with both Black-billed Magpie and Common Ravens reported from all circles. American Crow numbers were up with 13 birds in 5 areas. With the increase in snow cover compared to last year, it was not a surprise that Horned Lark numbers dropped dramatically. They were found on only 12 CBCs.

Black-capped Chickadee numbers increased significantly, with 4088 from 38 areas, with a jump of nearly one thousand individuals. Boreal Chickadee numbers were down slightly with 67 on 6 counts. Red-breasted Nuthatches staged a minor eruption, with 838 birds in 34 circles. Their White-breasted cousins also increased slightly compared to last season. Golden-crowned Kinglets dropped considerably, with the only reports coming from Saskatoon (1) and Shell Lake (2), as well as a cw bird at Prince Albert. Brown Creeper numbers were slightly lower with 18 birds noted on five CBCs, with one during cw. As mentioned earlier, a male Eastern Bluebird survived to be counted at Balgonie for only the second Sask CBC record. Sadly, but not unexpectedly, it succumbed during an extended bitter cold snap on February 9.

The only Townsend’s Solitaire report were count week birds at Estevan and Regina. Saskatchewan’s fifth CBC Hermit Thrush was well-described at Saskatoon. For the 4th consecutive CBC, American Robin numbers were low with only 25 birds reported from 11 areas, plus three during count week. Always a pleasant surprise, single Varied Thrushes turned up at Regina and Saskatoon, with a cw bird at Val Marie.

European Starlings showed up on 18 counts – with 5 during count week – but numbers were fewer when compared to last year. Bohemian Waxwings bounced back compared to the past two years with 6859 reported from 21 circles, with four more cw reports. However, the only Cedars were recorded during count week at Fort Qu’Appelle. Snow Bunting numbers rebounded from 2019, with 7969 on 35 counts. The only American Tree Sparrows were 5 found at Qu’Appelle. Dark-eyed Juncos were up slightly with 136 from 21 circles. Apparently no ‘Oregon’ types were noted among them this season. The Zonotrichia family was well-represented. White-crowned Sparrows were seen at Balgonie (1) and Pike Lake (2). There was a single Harris’s at Morse, with the more-expected White-throated on 6 counts, plus one cw bird at Biggar. The latter was new to their 50-year CBC list. It should be noted that Prince Albert counters found an amazing total of 18 White-throats, a new provincial CBC record!

Red-winged Blackbirds showed up in four areas, which is about average. The individual at Harris was new to their CBC list. After Estevan recorded a new-to-their-CBC-list count week Western Meadowlark last year, this time they found one on count day! Following no reports last year, single Rusty Blackbird’s turned up at Biggar, Gardiner Dam and Morse. Common Grackles were noted at Clark’s Crossing (3), Morse (1) and Saskatoon (2). A single Brown-headed Cowbird was a surprise at Eastend.

Winter finch numbers generally increased this CBC season. Pine Grosbeak numbers almost tripled compared to last year, with 878 reported from 24 counts, plus three more cw observations. While House Finches were reported from 17 areas – the same as 2019 – their numbers more than doubled to 1372 individuals. Purple Finches were recorded at Fort Qu’Appelle (1) and Whitewood (6), with two more sightings during cw. The only Red Crossbill reports came from Balgonie (31) and Floral (11). However, their White-winged cousins were up substantially with 617 birds on 13 counts, plus three more areas during count week. Common Redpoll numbers almost tripled, with 1850 from 32 areas and one cw record. Only 8 Hoarys were found in four circles, plus two in count week. Pine Siskin populations declined to half the number compared to last season, with 151 on 10 counts, plus two cw reports. In the meantime, American Goldfinch numbers were also down slightly, with 28 birds in 8 areas, plus two during cw. A most pleasant surprise was the number of Evening Grosbeak reports. There were 1120 birds seen in 11 areas, nearly doubling the total from 2019. Love hosted a most impressive 410 individuals!

While I personally feel House Sparrows have declined since I began birding in 1973, there still were 24,234 reported from 36 circles. When compared to last year, this was a substantial increase of just over 4000 individuals!
