Chestnut Breasted Mannikin

Males and females are identical in appearance. The only way to sex them is by behavior. The males will sing a song typical of many mannikins. With an upstretched neck and fluffed feathers, he will sing his warbling song and bounce back and forth on the perch while approaching the hen. They will sing often. In fact, most of the males in a cage will begin singing anytime a new member is added to the cage.
