According to research published online in September by the journal Science, wild bird populations in the continental U.S. and Canada have declined by almost 30% since 1970. The study quantifies for the first time the total decline in bird populations in the continental U.S. and Canada, a loss of 2.9 billion breeding adult birds—with devastating losses among birds in every biome. Join Ken Rosenberg, who leads joint research initiatives by the Cornell Lab and American Bird Conservancy, to learn why these study results transcend the world of birds.
