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 say avian keratin disorder is the cause of the elongated, fishhook-shaped beaks seen in Alaska's chickadee population. The condition causes abnormal keratin growth, leaving affected birds with overgrown bills that can make feeding difficult. Researchers studying the disorder are trying to determine what triggers it and how widespread it has become among the state's resident bird populations.
Why now: New research findings on the mysterious beak deformities affecting Alaska's chickadees have drawn public attention.
