The binding base devil ( neomorphus radiolosus ) is a cuckoo the Neotropics .

features

The cuckoo cuckoo is a large cuckoo that is about 46–51 cm tall. There is no such thing as gender dimorphism . The belly and neck area is black with white feather tips, the rear back and the cover feathers of the wings are chestnut brown. The wings are black, the wings are reddish to purple. The long control feathers appear shimmering black to dark purple. The blue-black shimmering large hood is striking . The eyes are dark brown, around them there is a featherless blue area that can be contracted and possibly serves as a signal or courtship sign towards the partner. The feet are colored blue-gray.

distribution and habitat

The banded cuckoo lives in tropical rainforests . It occurs only in the western foreland of the Andes along the Pacific Ocean in Ecuador and Colombia and is therefore endemic to the species-rich Tumbes-Chocó-Magdalena region . Observations of the bird are now rare, in the 1990s it was still frequently observed in the province of Nariño . It is assumed that only small, isolated populations remain. Due to the ongoing destruction of the habitat by clearing the forests and converting them to arable land, as well as the low population density and the small-scale distribution area, the IUCN assesses the cuckoo as endangered.

Way of life

Cuckoo cuckoos are often on the move in pairs, but are also spotted in swarms with various ant birds and tree climbers eating wandering ants . Little is known about the dietary composition of adult birds; it is believed to consist primarily of arachnids and insects and is collected from the ground or vegetation near the ground. White cuckoo cuckoos have been seen following collar peccaries, probably to catch prey startled by the peccaries.

The nest is built in forks at a height of about 4–5 m and consists of twigs and ferns (mainly Diplazium species), which are constantly being renewed. This could be due to the fact that chemical components of the vegetation keep parasites away or the heat generated by the decomposition of the vegetation improves the thermal insulation of the nest. The cuckoo cuckoo is not a breeding parasite , both parents breed and take care of the rearing of the young. Young animals are mainly fed with insects and small frogs , which could reflect the diet of the adult birds. You are probably monogamous. The way of life of the cuckoo cuckoo needs further research.
