The Tulukuckuck ( Centropus Toulou ) is an on Madagascar and Aldabra occurring bird from the genus of coucal ( Centropus ).
features
Tulukucku reach a body length of 40 to 46 centimeters and a weight of 117 to 139 grams for the males and from 131 to 189 grams for the females, whereby the individuals living in Madagascar are the heaviest. There is no sexual dimorphism between the sexes .

In the plain dress , the head, neck and throat are also hatched in white. The iris is red, the beak black, legs and feet are gray.
Distribution, subspecies and habitat
In addition to the nominate form Centropus toulou toulou , which occurs in Madagascar, another subspecies is known: Centropus toulou insularis Ridway , 1894, which is native to Aldabra. The species prefers to colonize eucalyptus and mangrove forests as well as reed beds on the islands from the plain to altitudes of 1800 meters.
Way of life
The birds feed primarily on various invertebrates , such as grasshoppers , beetles , as well as caterpillars and other larvae. Occasionally, lizards, small rats or young birds are also captured. The tulukuckuos sometimes hunt in pairs, with a partner defending the captured food against being stolen by other birds, for example the fork drongo ( Dicrurus forficatus ). The breeding season falls from July to September. The large, spherical nest is primarily made of dry grass and placed one to four meters above the ground in a dense bush and equipped with two to three eggs.
