Endemic to the mossy cloud forests of Papua, a Mountain Owlet-nightjar (Aegotheles albertisi) rests by the day in a thicket of vegetation. Biologists once believed that these strange cryptic birds (family Aegothelidae) were close relatives of the frogmouths due to their similar appearance and habits. Studies of their skulls has revealed that they are in fact more closely related to hummingbirds and swifts. Almost the entire family (7 of 10 species) is restricted to New Guinea.
