    Conservation DecliningCanada Warbler populations declined by over 2% per year between 1966 and 2015, resulting in a cumulative decline of 65%, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 4 million, with 82% breeding in Canada, and 18% in the U.S. The species rates a 14 out of 20 on the Continental Concern Score. It is a Tri-National Concern species, and a U.S.-Canada-Stewardship species. Canada Warbler is on the 2016 State of North America's Birds' Watch List, which includes bird species that are most at risk of extinction without significant conservation actions to reverse declines and reduce threats.Back to top
