The Halsbandastrild ( Nesocharis Ansorgei ), also Ansorge green avadavat called, is an African species of the family of finches . No subspecies are distinguished for this species.
description
Collared trilde reach a body length of ten centimeters. The male has a black head and a black throat. A narrow white band separates the black head from the blue-gray of the back of the neck and the sides of the neck. This band is much wider on the front breast and separates the black throat from the dark orange-yellow breast. The back, the rump and the wing covers are olive green, with the wings being a bit greener. The underside of the body is blue-gray. The beak is black with a bluish base. Females are largely similar to males, but have, similar to the titmouse , a blue-gray instead of a dark orange-yellow breast.
Distribution area and habitat
The distribution area of the Halsbandastrildes stretches from the west bank of Lake Albert in the north of the Democratic Republic of the Congo to Lake Kivu , western Uganda and northern Burundi to the far northwest of Tanzania . The habitat consists of open wetlands with only a few bushes and trees, and banks of watercourses with forests and bushes. It also occurs on overgrown cultivated land. The altitude distribution ranges from 1,000 to 2,100 meters.
Way of life
Collared trildes live in pairs or in small family groups. Their diet consists of small seeds. Collared trildes usually breed in the nests of other bird species. Usually it is around nests of Meisen- and glasses Weber , who build their nests hanging freely, so the nests probably before the visit of predators such as snakes and bush shrikes are better protected. The clutch consists of two to three white-shelled eggs that are incubated by both parent birds.
