Owl frogs (lat. Aegothelidae) are a family of goat-like, contains one genus with nine species. The range is limited to New Guinea, one species lives in Australia and Tasmania, another in the Moluccas and another in New Caledonia. They live in open and dense forests.
With their appearance, above all their round head and fit, they are similar to owls. However, they are smaller and reach lengths from 19 to 32 cm. Their eyes are located on the sides. The beak is small, stiff and surrounded by long bristles. Their legs are short in comparison with the body and graceful. Short, wide beaks are surrounded by bristly feathers at the base of the beak. The plumage pattern consists of thin dark waves on the main light color or of large white specks.
Birds, active at night and at dusk, rest during the day in tree hollows or on branches. They are loners. At night and at dawn, they look for insects, spiders and other invertebrates on the ground, or catch their prey in the air. Owl frogs nest in hollows of trees, sometimes also in caves on steep banks, and spend the day there. They do not build a real nest, but only spread the soil with leaves. In clutch there are 3 to 5 white eggs. The rest of their behavior is unknown. Birds make cooing sounds, soft whistles, loud hiss and harsh cries.
