The Aegothelidae family is made up of the owlet-nightjars. There are 10 species in this family.

They are found in New Guinea and Australia. Like their name suggests, they look like a cross between owls and nightjars.

Unlike some of the other members of the Caprimulgiformes order, they have tiny bills. Their bills are surrounded by bristles. While their bill is small, they can open it really wide.

They have soft plumage that is a mixture of black, brown, gray, and white. Their plumage looks like the bark of a tree and helps camouflage them during the day. Owlet-nightjars have large, round eyes and small feet.

Owlet-nightjars are nocturnal and eat insects. Owlet-nightjars usually hunt in the air, but sometimes they will hunt on the ground.
