Description wikipedia

The coral-billed ground cuckoo (Carpococcyx renauldi), also known as Renauld's ground cuckoo, is a large terrestrial species of cuckoo in the family Cuculidae. Its feathers have a glossy violet-black color. This bird can grow up to 65–70 centimeters in size. It is found in Cambodia, Laos, Thailand, and Vietnam. Its natural habitat is tropical moist lowland forest. These birds feed on small invertebrates or insects. Animals like Shrews, Squirrels, Snakes, and Macaques are great threats to these birds and their nests. Its English name refers to its coral-red bill, which separates it from the two other members of the genus Carpococcyx. This species of cuckoo is known in Thailand as nok korokoso (Thai: นกโกโรโกโส, pronounced [nók koː˧.roː˧.koː˧.soː˩˩˦]), which literally means "shabby bird". It is said that it got this name because when Boonsong Lekagul was compiling a list of various types of birds found in Thailand. Specimen of this bird was kicking around the floor in a ragged state. Hence came the name.
