mountain owlet-nightjar Aegotheles albertisi

A small owlet-nightjar of montane forests. Dark head, pale collar, barred back and tail. A rufous morph also occurs. Day-roosting birds are sometimes found in dense thickets. May overlap with Wallace’s Owlet-nightjar, which lacks the pale collar, and Vogelkop Owlet-nightjar, which has a barred chest. Call, a sharp falling “wek!” or “wek-wek!” sounding like a squeaky toy or given as a raspy note.
