The yellow-mantled widowbird (Euplectes macroura), also known as the yellow-backed widow, was originally named after the city of Ouidah in Benin. Males are larger than females and acquire longer tails and striking black and golden yellow plumages in the breeding season. The mantle colour is either golden yellow, or black in the northeastern race, Euplectes macroura macrocercus. The yellow shoulders are in all male plumages, breeding or non-breeding. It is widely found in Africa.
