A malignant melanoma was reported in the left patagium of a budgerigar (Melopsittacus undulatus).
Abstract: An adult male prairie falcon (Falco mexicanus) was presented for evaluation and treatment of self-inflicted wounds along the right proximal patagium.
However, the bird was observed chewing on the patagium of the right wing on day 42 after the bandages were removed and the previous wounds had appeared to be completely healed.
Over the next 5 days, occasional chewing at the right patagium was observed, but the wounds continued to heal, and the skin closed completely by day 52.
