Canaries in the Mine: Three Billion Birds Lost

April 29, 2020
7:00 p.m. to 9:00 p.m.

Last year, the headlines that 3 billion birds have disappeared from North America since 1970 shocked the world and captured our attention. The source of the news was “Decline of the North American Avifauna,” published in the journal Science by author Ken Rosenberg of the Cornell Lab of Ornithology and his team of coauthors, including local avian conservation scientist, Arvind Panjabi, from Bird Conservancy of the Rockies. This groundbreaking research combined population sizes and trends for 520 species of birds, with much of the data coming from Bird Conservancy’s Avian Conservation Assessment Database. Arvind will share how the study was conducted, where the greatest certainties and uncertainties lie, and what it means for birds in Colorado and across North America. He’ll also share ways we can all can help reverse bird population declines including simple steps we can take in our daily lives and backyards. This program is presented in partnership with Bird Conservancy of the Rockies with promotional support from Audubon Denver and Audubon Rockies.
