The black bridle tiger ( Estrilda nigriloris ) is a hardly researched bird species from the family of the finches . No subspecies are distinguished for this species. Due to its similarity to the wave astrild ( Estrilda astrild ) it is considered by some researchers as its subspecies.
features
The black bridle tiger reaches a length of 11 centimeters. There is no pronounced sexual dimorphism . The wing length is 46 millimeters, the tail length 45 millimeters, the beak length 8–9 millimeters and the barrel length 16 millimeters. It differs from the wavy reindeer in the black instead of red rein and eye area as well as in the shorter and more compact beak. A diamond-shaped spot runs through the eyes and a fine reddish-white line above it. The fawn to gray plumage is banded on the flanks and belly with a fine wave pattern. The rump is black.
distribution
The black rein tiger occurs in the Democratic Republic of the Congo . Evidence is available from the Lualaba valley south of Kiabo , Katanga , Kaleka , Zombe , Mabwe and Lake Upemba .
Way of life and habitat
Almost nothing is known about the way of life of the black grouse. He lives in the swampy areas between the Lualaba River and Lake Upemba . Foraging, voice and breeding biology are believed to be similar to the behavior of the wavelike deer.
status
The black reins have not been sighted since 1950. The IUCN lists it in the “ data deficient ” category , as further studies are necessary to clarify its status as a valid species, its population status and its distribution.
