A study published in Science reveals that North American bird populations are declining most severely in areas where they should be thriving. Researchers from the Cornell Lab of Ornithology analyzed 36 million bird observations shared by birdwatchers to the Cornell Lab’s eBird program alongside multiple environmental variables derived from high-resolution satellite imagery for 495 bird species across North America from 2007 to 2021.
