The family Caprimulgidae, commonly known as nightjars, consists of medium-sized birds found worldwide, primarily in open habitats like forests, grasslands, and deserts. They are known for their cryptic plumage, which helps them blend into their surroundings, making them difficult to spot during the day. Nightjars are nocturnal and are most active at dusk and dawn. They have a distinctive call, often described as a soft, repetitive sound, which they use for communication and attracting mates. Their diet mainly consists of insects, which they catch in flight using their wide mouths.
