Caprimulginae or typical nightjars, is a subfamily of nightjars in the Caprimulgidae] family. They are medium-size with long wings, short legs, and very short bills. They usually nest on the ground. They feed on flying insects. They have small feet, of little use for walking, and long pointed wings. Their soft plumage is cryptically coloured to resemble bark or leaves. Some species perch facing along a branch, rather than across it as birds usually do. This helps to conceal them during the day. The female lays two patterned eggs directly onto bare ground.
