The eastern population of the Loggerhead Shrike in Canada is on the brink of extirpation and there are several key questions that must be answered as soon as possible to conserve this species. Initiated in 1999, the Loggerhead Shrike colour banding program in Ontario is intended to furnish much needed information on post-fledgling survivorship, immigration and emigration rates among and between the four sub-populations in Ontario (Napanee, Smiths Falls, Carden and Grey-Bruce/Manitoulin), longevity, age structure, overall population size, and site faithfulness. It will also help assess the efficacy of a planned release program, and could contribute some information on wintering areas.
