The dusky nightjar (Antrostomus saturatus) is a species of nightjar in the family Caprimulgidae. It is found in Costa Rica and western Panama. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.
Also sometimes called the Dusky Whip-poor-will, on account of it being perhaps more closely related to the other whip-poor-wills than to other New World Antrostomus, this nightjar is restricted to a relatively small range in southern Central America. It occurs from central Costa Rica to westernmost Panama, where it is found in montane forests and woodland between 1500 and 3100 m. This is a mid-sized brownish nightjar characterized by its buff throat band and lack of white wing markings; males have white tips to the outermost rectrices, but these tips are buffish in females. Although Dusky Nighthjar is locally common, very little appears to have been published concerning its ecology or behavior.
