gressnattravn Caprimulgus affinis

Well-camouflaged nightbird, usually encountered roosting on gravel riverbeds, open areas in grasslands, rooftops, or roadsides. Sometimes found in small loose flocks when roosting. Fairly well adapted to urban life in some parts of its range and often found in towns and city edges. Intricately patterned gray-brown with less white than other nightjars; only males have a fairly small white patch on the wing near the tip. Most often detected by its distinctive, high-pitched, burry “chree-ik” song, repeated over and over.
