The Coral-billed Ground Cuckoo is one of three species of Ground Cuckoo in the genus Carpococcyx that look similar and inhabit forested areas of Southeast Asia. It is the only one with a red bill. It is also spelled Ground-cuckoo. (The Red-billed Ground Cuckoo is an unrelated South American species from a different genus.)
A large, ground-dwelling bird, larger than a Wood Pigeon but smaller than a Pheasant Pigeon, the Coral-billed Ground Cuckoo has iridescent blue on its black head and long tail. Male and female have similar plumage. Although ground-dwelling, they roost and nest in trees. Despite being called cuckoos, they incubate their own eggs (both sexes taking turns).
