Avian keratin disorder blamed for deformed beaks in Alaska chickadees
Original: Scientists believe avian keratin disorder is cause of fishhook beaks in Alaska chickadee population
Scientists in Alaska say avian keratin disorder is behind the fishhook-shaped beaks appearing in the state's chickadee population. The condition causes abnormal growth of the birds' beaks, which can make feeding difficult. Researchers studying the disorder are working to understand its causes, and the findings have drawn attention given the unusual number of affected birds reported in the region.
Why now: New research has identified the likely cause of a striking beak deformity affecting Alaska's chickadees.
