Beak Deformities

The Alaska Science Center began research on an epidemic of beak deformities in landbirds in Alaska in 1999 and has since identified more than 2,000 Black-capped Chickadees affected by this disorder in Alaska—the highest concentration of such abnormalities ever recorded in a wild bird population anywhere!  More recently, rapidly increasing numbers of other species, including Northwestern Crows, Downy Woodpeckers, Steller’s Jays, and Black-billed Magpies have also been reported with bill deformities by biologists and local residents.
