The coral-billed ground cuckoo ( Carpococcyx renauldi ) is home to a Southeast Asian cuckoo, the tropical forests in the undergrowth and is staying there mostly on the ground. In contrast to numerous species in the cuckoo family, the Renauld cuckoo is not a brood parasite , but rather raises its young birds itself. No subspecies are distinguished for this cuckoo.
The German name and the specific epithet honor the French missionary JN Renauld (* 1838; † 1898), who collected numerous specimens of the Vietnamese flora and fauna during his missionary work in Vietnam and whose collection founded the Vietnamese Natural History Museum in 1898.
features
The Renauld cuckoo, which reaches a body length between 65 and 70 centimeters, is a long-tailed cuckoo with a compact body, which is reminiscent of a pheasant because of its posture . The tail feathers in the male reach a length between 29 and just under 35 centimeters, in the females it is an average of 33 centimeters long.
There is no pronounced gender dimorphism . The body plumage is predominantly colored light gray. The head, neck, chest, tail, front chest, and hand wings are shiny black. The featherless facial fields are colored blue, with wide purple circles under the eyes and yellow eyes. The strong beak and the long, equally strong legs and feet are colored coral-red.
Young birds still have a dark brown head with a reddish-brown forehead, the bare facial skin around the eyes is gray. The upper side of the body is also still brownish and the torso is reddish-brown speckled. Their beak is still dark brown.
Occurrence
The Renauld cuckoo is a ground dweller in damp forests with dense vegetation. It can be found in Thailand , Laos , Cambodia and Vietnam and is a resident bird. In Thailand it occurs at altitudes of up to 900 meters, in Indochina it is very rarely found at 1500 meters above sea level.
behavior
The Renauld cuckoo is mostly on the ground and moves around like a pheasant. If it trees, it prefers the lower branches of trees. It rarely flies open, although it can fly quickly. The Renauld cuckoo is very difficult to observe in the wild because of this secret way of life. Most of the knowledge about his way of life was gained in the zoo.
The bird feeds on various small animals. The birds keep in contact with each other by calling. The couples sing in a duet with hard, deep whistling tones.
Reproduction
This type of cuckoo is not a brood parasite. Renauld cuckoos kept in captivity build a shell nest of twigs and leaves on the ground or in trees at a height of three to four meters. The only nest documented in the wild was just five meters above the ground. The clutch consists of two to four eggs with a white shell color. The eggs are laid with an interval of two to three days. Both parent birds breed and row the nestlings.
The nestlings hatch after an incubation period of 18 to 19 days. You are initially naked and have dark brown skin. The eyes open on the fifth day. They leave the nest when they are between 17 and 19 days old and start searching for food independently on their 28th day of life. With 50 to 60 days of life they are independent of the parent birds.
Danger
There are no population size estimates, the species is not considered to be endangered. Renauld cuckoos are hunted in Thailand, but also caught for the bird trade.
