Southern Ground Hornbills singing
These pre-historic-looking birds are black with white flight feathers and a red wattle. You can recognize females by the blue patch on their red wattle. Males have bare facial skin and a wattle that can expand. These neck wattles are used to make booming or grunting sounds, often just before dawn.
Southern ground-hornbills are carnivorous—eating lizards, frogs, snakes, snails, and insects. They are able to fly, but spend the majority of their time on the ground. They hunt in groups by walking (instead of hopping), probing, pecking, and digging at the ground.
These birds live in cooperative breeding groups made up of a dominant pair and several subordinate adult males. This dominant pair successfully breeds only once every nine years, with only one surviving chick per nest.
