National Audubon Society has identified 152 highly vulnerable species in the Central Flyway.
According to a Cornell Lab of Ornithology study published in 2019, North America has lost 1 in 4 birds over the last 50 years. Grasslands in particular posted the biggest losses, with more than 720 million breeding individuals lost across 31 species since 1970, a 40 percent decline. Two-thirds of North American birds are at increasing risk of extinction from global temperature rise.
