The Tajazu Cuckoo ( Neomorphus geoffroyi ) is a cuckoo species of the Neotropics . There are up to seven subspecies .
features
The Tajazu Cuckoo is about 45 to 51 centimeters tall. There is no such thing as sexual dimorphism . The strikingly large hood is colored glossy black and blue. The forehead and neck area is cinnamon-colored with dark feather tips, making the feathers appear like scales. The upper side and the wings are brown to olive brown in color and shimmer bluish to purple. The control feathers are black and have a purple to greenish sheen. The colors vary between the subspecies. The breast plumage and the underside are brownish to gray, with the feather tips above the black chest band being black and like the forehead area appearing like scales. In some subspecies, the black chest band is not continuous, instead the chest and flanks have black feather tips and a scale-like appearance. The curved beak is greenish yellow. The color of the iris varies between yellow, red and brown, the eye is surrounded by a featherless gray-blue ring.
Systematics, distribution and habitat
The exact system of the tajazu cuckoo is controversial. Six to seven subspecies are distinguished depending on the author. The shed ground cuckoo ( Neomorphus squamiger ) is sometimes listed as a subspecies of the Tajazu cuckoo ( Neomorphus geoffroyi squamiger ).
The Tajazu Cuckoo inhabits large parts of South America . The individual subspecies have the following distribution areas:
- N.g. geoffroyi ( Temminck , 1820): Central Brazil on the Amazon
- N.g. salvini ( PL Sclater , 1866): Central America from Nicaragua to Panama
- N.g. aequatorialis ( Chapman , 1923): Colombia , as well as eastern areas of Ecuador and Peru
- N.g. australis ( Carriker , 1935): Southern areas of Peru and northern Bolivia
- N.g. maximiliani ( Pinto , 1962): Brazil in the state of Bahia along the coast
- N.g. dulcis ( Snethlage , 1927): Brazil in the state of Rio de Janeiro along the coast
The Tajazuikuckuck inhabits tropical rainforests such as B. Terra Firme forests or Atlantic rainforests . Despite the ongoing destruction of the habitat and the low population density , the IUCN does not consider the species to be endangered due to its large distribution area .
Way of life
Like other members of the subfamily of earth cuckoos , the tajazu huckuck usually moves on the ground, trees are visited to sleep or to care for feathers. Most of the food is collected from the ground. The Tagus huckuck follows the wandering ants of the genus Eciton or umbilical pigs to catch startled prey. For the same reason, it is also often found near squirrel monkeys ( Saimiri ) and capuchin monkeys ( Cebus ). The diet consists mainly of insects , scorpions , small frogs, lizards and birds, and fruits are also eaten occasionally. The species is often found together with other birds, such as B. the crow's forehead bird ( Psarocolius decumanus ) or various ant birds sighted. Like the other species of the genus Neomorphus , the Tajazu Chuckuck is not a breeding parasite ; the young are raised by both parents, with the clutch consisting of a single egg. The nest is built in the thicket at a height of 2 to 5 meters and lined with fresh leaves, which are constantly renewed during incubation.
