African penguins are also called jackass penguins because they emit loud donkey-like brays, yells, and haws to communicate.

African penguins are also called jackass penguins because they emit a loud, braying, donkey-like call to communicate. There are three types of calls used: bray, yell, and haw.

The yell, or contact call, is used to defend a territory from another colony member. The bray, or display call, is used to attract mates and is used between partners in a colony. Penguins also perform displays that are used to establish nesting areas, help with partner/hatchling recognition and defense against intruders. The haw is used by partners when one is on land and the other is in the water.
