The yellow bridge weaver ( Ploceus dichrocephalus , also misspelling dicrocephalus ) belongs within the family of weaver birds (Ploceidae) to the genus of the bunting weaver ( Ploceus ).
The Latin additional species comes from ancient Greek διχρους dichrous , German 'two-colored' and ancient Greek κεφαλος kephalos , German 'head' .
The bird is found in the Horn of Africa in southern Ethiopia , in the extreme northeast of Kenya and in southwest Somalia .
The distribution area includes moist habitats on river banks in Kenya and Somalia, in the savannah in Somalia and Ethiopia, even in semi-deserts , also around cultivated land .
features
The species is 13 cm tall and weighs between 18 and 20 g. The male has a black-brown head in the breeding plumage, which turns into a lighter chestnut brown in the neck. The top is greenish-yellow, the rump light yellow, the tail olive-green. It is similar to the Jackson weaver (Ploceus jacksoni) and black- headed weaver (Ploceus melanocephalus), but the mask is black on the crown with blackish-chestnut blue blending on the neck and cheeks. The iris is reddish-brown, washed-out chestnut brown under the eye. Males in plain dress like females and young birds resemble the black-headed weaver female, but the underside is more yellow and the beak is clearly two-colored.
The species is monotypical .
voice
The male's singing is described as inharmonious, somewhat swallow-like squeaking, snoring and humming sounds.
Way of life
The diet consists mainly of seeds, probably also of insects . The species generally occurs in pairs and small groups.
The breeding season in Ethiopia is in March. The bird is probably polygynous and breeds in small colonies in trees or in reeds. The oval nest has almost no entrance. The clutch consists of two pale greenish-blue or gray-green eggs, spotted brown and purple.
Hazardous situation
The stock is not considered to be at risk ( least concern ).
