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 the cause of the fishhook-shaped beaks increasingly seen in the state's chickadee population. The condition causes abnormal keratin growth, leaving birds with overgrown, curved beaks that can make feeding difficult. The finding, reported by the Anchorage Daily News, offers an explanation for a deformity that has puzzled researchers observing Alaska's backyard birds for years.
Why now: New scientific findings explain a troubling and visible beak deformity affecting Alaska's chickadees.
