The Pallid Cuckoo is identified by its grey plumage, which is darker on the wings and back, and its broadly barred black and white undertail. The bill is brown, the legs and feet are grey-brown, and there is a bright yellow ring around the eye. It is a large, slender cuckoo and is somewhat hawk-like in appearance during flight. Young Pallid Cuckoos are mottled with brown and buff above, with a white spot on the nape, and are streaked with grey-brown and white below. As with other species of cuckoo, its call often betrays its presence long before it is seen.
