Today The State of Canada’s Birds 2012 was released. Forty-four per cent of Canada’s 460-plus bird species have decreased in population numbers since 1970, 66 species of them so dramatically that they are considered endangered.

June 27, 2012 (Ottawa) Canada’s bird populations have been heavily influenced by human activity, in ways that have helped some species and hindered others, according to a first-of-its- kind national report on the state of Canada’s birds.
The State of Canada’ s Birds report draws on 40 years of data – from professionals and citizen scientists – to present an overview of how Canada’s birds are faring. It summarizes the status of Canada’s bird populations for eight regions, including the boreal forest, prairies, Arctic and oceans. This scientific report also identifies the most significant conservation opportunities for Canadians to ensure healthy bird populations and healthy ecosystems.
The report finds that there are fewer birds now than in the seventies – on average, Canadian bird populations have declined by 12%. However, some species are doing well, while others are declining. Overall, more species are decreasing (44% of species in Canada) than increasing (33%). Some groups have severely declined, including grassland birds, migratory shorebirds and aerial insectivores (birds that catch insects in flight). These groups have all decreased by more than 40%, on average, and some individual species in these groups have decreased by more than 90%.
Other species have increased as a result of successful conservation efforts. The ban on pesticides in the 1970s has helped raptors like the Peregrine Falcon, Osprey and Bald Eagle recover. Effective management of wetlands and hunting has aided waterfowl (ducks and geese).
Birders across Canada helped with the report. From the acknowledgements section: “This report would not have been possible without the dedication and skill of the thousands of volunteer observers who are the backbone of many monitoring programs, such as the North American Breeding Bird Survey, shorebird migration surveys, and the Christmas Bird Count. Similarly indispensable were the many professional biologists and technicians from across Canada and internationally who designed and helped to conduct and report on all the diverse programs monitoring Canada’s birds.” The report was released by the North American Bird Conservation Initiative, under the leadership of Environment Canada, Bird Studies Canada, Ducks Unlimited Canada, Nature Canada, the Nature Conservancy of Canada, and Wildlife Habitat Canada.
