Choco Poorwill

The Choco Poorwill (Nyctiphrynus rosenbergi) is a nocturnal bird in the nightjar family Caprimulgidae, endemic to the humid lowland and foothill forests of the Chocó biogeographic region on the Pacific coast of Colombia and northwestern Ecuador. Members of the genus Nyctiphrynus are small nightjars characterised by their cryptic bark-like plumage of mottled greys, browns, and blacks, wide gape for catching flying insects in flight, and the white or pale spots on the outer tail feathers visible in flight. The Choco Poorwill rests on the ground or on low horizontal branches during the day, relying almost entirely on its camouflage for protection, and becomes active after dark when it forages for moths, beetles, and other flying insects attracted to forest clearings and edges. Like other poorwills, its haunting call — a series of mellow whistled notes — is more often heard than the bird is seen. The IUCN classifies this species as Near Threatened owing to the rapid and continuing deforestation of the Chocó lowlands for agriculture, logging, and human settlement. The Chocó region harbours extraordinary biodiversity and endemism, and the ongoing loss of its forests puts specialised species like this nightjar at increasing risk.
