reproduction

As the European cuckoo and other birds of his family, does not own nests. It lays its eggs in the nests of other species, leaving the foster parents hatch and raise their young. Search birds that make great nests and closed with a small entrance, like the Spix's Spinetail and Yellow-chinned Spinetail (Certhiaxis cinnamomeus) as pictured below. Although much larger than the parasitized species or their eggs have similar dimensions to forced host. The position is made when the adoptive parents are beginning to lay eggs and hatch faster than the nest brothers. At birth, the cub has a powerful beak, with a shaped tip pliers, used to kill the other children as they are born. Thus, ensures food supply compatible with its larger size and growth rate. The adoptive parents unfold to get the food sacizinho, which follows asking for food, even after leaving the nest, with 18 days of life. At this stage already has two or three times the size of the host.
habits

While it is easy to listen to, it is difficult to observe. He lives alone, occupying open areas near clumps of forest, mountain ranges or with sparse trees. Do not use areas with low vegetation, being hidden in the long grass or arbustos.Canta landed in the lower branches of a tree or shrubs, at which can be seen better, if detected in time. At any sign of danger, flies into the woods or hides in the bushes.
