Diabolical Nightjar Eurostopodus diabolicus

A dark, cryptically patterned nightjar with a bold buff collar, and prominent pale gray patches on the upperparts. In flight, note the small white mark on the outer wing. Inhabits forest and edges in the foothills and mountains. Pairs often roost on the ground. Restricted to Sulawesi. Never shows white in the tail, unlike Sulawesi and Savanna Nightjars. Smaller than Great Eared-Nightjar, and never hawks above the canopy. Song is a rapid series, “ke-ke-ke-ke-ke-ke.” Also gives soft “whip” calls.
