The Order Caprimulgiformes consists of nocturnal or crepuscular birds commonly known as nightjars, nighthawks, and frogmouths. These birds are characterized by their camouflaged plumage, wide mouths for catching insects in flight, and small legs adapted for perching rather than walking. Most are insectivorous, feeding primarily on flying insects at dusk or night, and they have large eyes and sensitive hearing to navigate in low light. Caprimulgiformes are found worldwide, especially in tropical and temperate regions, and play an important ecological role in controlling insect populations.
