Also known as the Golden bishop or yellow crowned bishop, the striking yellow colour only occurs in the male.
They use their brightly coloured feathers in two ways. Firstly, as a warning to other male bishops to stay away and secondly, to attract a female. They do this by fluffing their feathers up and calling out.
The Napoleon bishop weaver is found in Africa, towards the bottom end, below the Sahara desert. They move around a bit too, depending on the time of year. If it’s the breeding season then they like to move to marshy and flooded areas and at all other times will make their way back to drier areas.
