Deformed, crossed bill, probably from Avian Keratin Disorder. Avian Keratin Disorder is characterized by dramatic beak deformities such as elongation, crossing, or curvature, and disables infected birds by severely impairing basic behaviors—including feeding and preening—that are crucial to their survival. First documented among a population of black-capped chickadees in south-central Alaska during the 1990s, AKD has seemingly spread into Canada and the Pacific Northwest, and similar deformities have also been reported in several species throughout the lower forty-eight states. The disease's hallmark traits have recently been observed in regions as far-flung as Europe and Asia. Aside from chickadees, the other species most commonly affected are nuthatches, woodpeckers, crows, jays, and other members of the crow family.
