A 4-week-old female Northern goshawk (Accipiter gentilis) presented with a valgus deformity of both wings resulting in dorsolateral rotation of the primary flight feathers. The condition resolved in 2 weeks after the wings were bandaged and physical therapy was performed. This type of valgus deformity is also known as angel wing. It has been frequently described in waterfowl and has been reported in bustard chicks as well as psittacine birds (budgerigars, macaws, and conures). To the best of the authors' knowledge, this is the first report in a peer-reviewed publication describing angel wing and its treatment in a raptor.
