The Anambra Waxbill ( Estrilda poliopareia ), also Anambra-Astrild written is an African bird art from the family of finches . It has a very small range and the total population is estimated to be less than 1,000 individuals. The IUCN therefore classifies the Anambraastrild as endangered ( vulnerable ).
description
The Anambraastrild reaches a body length of twelve centimeters. There is no noticeable sexual dimorphism , the females are just a little paler on the underside of the body.
The Anambraas is grayish-brown from the top of the head to the back of the back. The upper tail-coverts are orange-red, the brownish black tail is slightly tiered and clearly striated across. The underside of the body is dark yellow and white, which turns into a light brownish on the sides of the body. The under tail-coverts are whitish ocher. The main distinguishing features of the swamp fawn are the bright eyes and the powerful beak.
distribution
For a long time, the Anambraas was only observed in three to four places on the lower Niger in southern Nigeria . In the meantime, a population in the south of Benin has also been detected.
Its habitat is high grass and reed thickets along large rivers. He has also been seen on manioc plantations . Anambraastrilde live in pairs and in small groups of up to twenty individuals, occasionally also together with flocks of other species of fine finch. The food consists of grass seeds, which Anambraastrilde peck directly from the ears of grass. No further behavior is known from field observations.
Systematics
The species status of the Anambraastrild has so far been discussed without final clarification. While Sibley & Monroe consider him a good species, Dowsett & Forbes-Watson place him as the sixth subspecies to the closely related swamp fawn Estrilda paludicola , whereby they refer solely to the evaluation of photos. In the specialist literature, the classification as Estrilda poliopareia predominates .
