About These Birds
Bertram's Weaver
Bertram's Weaver is a weaver bird found in montane forests and woodland edges of the Eastern Arc Mountains of Tanzania and adjacent Malawi. It has yellow and black breeding plumage typical of many weavers and builds woven nests. It feeds on seeds and insects in forest edges and clearings.
Black-necked Weaver
The Black-necked Weaver is a medium-sized weaver; males have a black head and neck, golden-yellow body, and brown wings, while females are more streaked. It inhabits dense forest edges, secondary growth, and tall vegetation near water in west-central Africa. Males build woven hanging nests in colonies, and the species feeds on seeds, insects, and berries.
