Finn's Weaver Ploceus megarhynchus

Range-restricted weaver with a powerful dark bill. Male is predominantly yellow with a dark cheek patch. Female is streaky brown above and paler below; lacks the strong streaking and facial patterns of Streaked and Black-breasted Weavers. Female Finn’s is similar to female Baya Weaver, but note the darker coloration, lack of a pale brow stripe, and heavier, sharper-looking bill in female Finn’s. Inhabits open areas with scattered trees; favors wet areas. Colonial nester; males build ball-shaped nests, often in cotton trees.
