Long-tailed Nightjar Caprimulgus climacurus

A slim nightjar with a very elongated tail. Varies geographically; plumage usually rufous-brown or gray-brown, but locally dark brown. Both sexes have a large pale mark in the outer wing and along the sides of the tail, white in males and buff in females. Molting and non-breeding birds can have a shorter, though still elongated tail. Found in a wide variety of savanna and other open habitats. Similar to Slender-tailed Nightjar, but usually longer-tailed, and plumage is more rufous in the area where their ranges overlap. Call is a very fast, mechanical trill, higher-pitched than similar calls of other nightjars. Also gives a “chiow” call, often in flight.
