B.C. Waterbirds Abundance Maps

This page contains maps of waterbird abundance based on the BC Coastal waterbird survey for 3 BC regions: South Coast, Northern Vancouver Island and North Coast. Maps show average densities of bird groups from December to February from 1999-2012. Highest density areas appear red, and lower density/zero data are in yellow. Survey coverage is generally greatest on the south coast and therefore more data is available at those sites. Coastal areas that are not coloured have not been surveyed. Each map shows abundance for a specific guild, or group of similar waterbirds. For example, data is combined for Rhinoceros Auklet, Cassin's Auklet, Ancient Murrelet, Marbled Murrelet, Pigeon Guillemot, Common Murre and unidentified Alcid for the Alcid group. The species comprising each guild are listed on the maps using standard 4 letter bird codes. Please note that many sites do not have count data for all months and years.

We thank the Real Estate Foundation of BC for supporting this mapping work. For further information, please contact David Bradley BCprograms@birdscanada.org
