The Crested Pigeon is a stocky pigeon with a conspicuous thin black crest. Most of the plumage is grey-brown, becoming more pink on the underparts. The wings are barred with black, and are decorated with glossy green and purple patches. The head is grey, with an pinkish-red ring around the eye. If startled, this pigeon takes to the air with a characteristic whistling flight, and glides with down turned wings. The whistling sound is produced by the air passing over a modified primary feather on the wing. Upon landing, the pigeon swings its tail high in the air.
