The yellow-crowned bishop (Euplectes afer) is a weaver that gets its name from the male's breeding plumage: bright yellow crown/head contrasting with black body, resembling a bishop's vestments with a yellow mitre, while "Bishop" comes from male's black body and bright head, resembling the robes and mitre of a Christian bishop. Males have vibrant yellow and black breeding plumage to attract mates, while females are plain brown. The Yellow-crowned Bishop lives across sub-Saharan Africa, preferring open grasslands, wetlands, and cultivated fields, moving nomadically to wet, flooded areas for breeding and drier spots otherwise. It's found from Senegal to South Africa, often near pans and river systems, but has also been introduced to places like Portugal, Jamaica, and the US (Florida).
