Staffelschwanz-Nachtschwalbe Hydropsalis climacocerca

Large nightjar of tropical lowlands, often found near waterways. Sandy brown with indistinct light markings and a fairly long tail; in flight, males show large white wedges on outer tail feathers. Roosts during the day in vegetation along the edges of oxbow lakes and rivers and forages around sandbars and river edges at night. Does not call often, but occasionally gives soft chirping calls in flight.
