Diademweber Euplectes diadematus

Breeding males are beautiful and unmistakable, with black-and-yellow plumage and a distinctive red forehead patch. Females and non-breeding males are brown and streaky. Found in grassland, cultivation, and arid savanna. A nomadic species that appears in large numbers after rains. Often mixes with other species when not breeding. The song is a high-pitched twittering. Non-breeding males and females are very similar to other bishops, but are smaller than most, with more prominent yellow edges to the wing feathers.
