The mountain bronze male ( Lonchura kelaarti ) is a species from the finch family . There are three subspecies. The IUCN classifies this species as not endangered (“least concern”).
description
Mountain bronze males reach a body length of 12 to 13 centimeters and weigh on average 14.1 grams. There is no sexual dimorphism .
Both sexes are predominantly chocolate brown on the upper side of the body. The forehead is a little darker, the rump is brown or black, depending on the subspecies. The upper tail-coverts are yellowish red-brown and the tail is black-brown. The reins, the sides of the head, and the throat and front chest are black. The sides of the neck are pale yellowish brown. The eyes are brown, the beak blackish gray. The feet and legs are dark slate gray.
Fledglings are brown on the top of their bodies with darker wings and a dark tail. On the underside of the body they are yellowish brown with whitish streaks.
Distribution and way of life
Mountain bronze males are at home in Southeast Asia. Their distribution area extends from Sri Lanka to eastern India . They live there at altitudes of up to 2,100 meters. In the mountainous regions of Sri Lanka, they can be found predominantly between 600 and 2,100 meters altitude, but during the rainy season they also come down to an altitude of 200 meters. Their habitat are light forests, where they prefer to stay in clearings and at the edges of the forest, as well as grassy areas. But they also occur on tea plantations and breed in the bushes on the edges of fields. Occasionally they even use climbing plants on house walls.
Outside the breeding season, this species lives in small groups.
The clutch usually consists of four to six eggs. These are incubated for 14 days. The nestling period is 23 days. After leaving the nest, the young are looked after by the parent birds for another two weeks.
attitude
Mountain bronze males are only introduced very rarely and are still among the seldom kept splendid finch species, even though they are now regularly brought up by some breeders. Most of the mountain bronze males kept in Europe are descended from only a few parent pairs, so that inbreeding depression is increasing . In addition, there are numerous hybrids of mountain bronze males with other bronze males as well as the Japanese gull , a domesticated form of the pointed-tail bronze male .
