Dusky Nightjar (Caprimulgus saturatus) Science Article 1
Crepuscular and nocturnal caprimulgids (nighthawks and nightjars) form a particular group of insectivorous birds (Junge 1964). During daylight hours, they roost on the ground or low in vegetation, often in open situations exposed to full sunshine. During twilight and nighttime hours they become active, feeding entirely on night-flying insects. Their eggsare laid on the ground. Clutches consist of I or 2 eggs incubated by male and female, and both care for the young.
