The aim of this study was to determine the type of lesions in birds referred to the clinic with
the complaint of beak deformity, the potential presence of the lesions among the bird species,
and the possible causes of the lesions and to report what treatment should be applied. Twentysix individuals from several bird species with broken beaks and abnormal beak deformities
were presented to our clinics. Different forms of beak deformities were observed, and the
causes of some of the lesions were determined as unknown. Beak lesions in wild birds were
mostly traumatic fractures, whereas cage birds had parasitic infections and abnormal beak
elongation due to nutritional disorders. Treatment protocols appropriate for each case,
severities of the lesions, underlying causes, and species of the birds were determined.
