Order Caprimulgiformes / Nightjars, Frogmouths, & Oilbirds

All of the birds in the order share several features:

• As the name suggests, nightjars and their relatives are usually active at twilight or night.
• Caprimugiformes have large heads with large eyes.
• The bills of these birds can open very wide-this feature is called wide gape.
• As the birds in the order are mainly nocturnal, they have a simple coloring rather. The feathers are usually black, brown, grey, and sometimes brownish yellow or red.
• Some species may also have patterns on their bodies.
• Most of the birds in the order are relatively small, from 6 to 16 inches, and are also of low weight.
• The wings and tails of Caprimulgiformes birds are long.
• Another prominent feature of this order is the presence of a serrated claw on the middle toe. The serration often resembles teeth of a comb.
• These birds mainly feed on insects; some catch them in the air, while other species find them in the ground.
• The nesting habits vary from species to species. While some birds do not make any nest whatsoever, others build a nest on trees on a nest in caves.
• Both parents feed the chicks that develop for approximately 20 days.
• These birds are known for well-developed voices; the sounds they make can often be heard at night and are sometimes subject to legend.
• The birds of this order can be found around the world, except some islands and Antartica.
