Bird Calamity

K. Ouchley

An article recently published in the journal Science rattled the American conservation community like no other. The paper summed up the results of multi-faceted research by the premier avian science groups in the country. It included analyses of years of breeding population data on 529 species of birds. Additionally, it considered decades of radar data that track bird migrations. It's the best science that exists, and it says there are almost 3 billion fewer birds in North America than 48 years ago; more than I in 4 have disappeared.
