Eurostopodus diabolicus is endemic to Sulawesi, Indonesia, where it is known from mountain ranges in the north and centre of the island. Large (30-32cm), Entirely dark with a pale rusty-buff throat-band and inconspicuous small white mark on 4th primary (numbering commencing at outer wing); no white in tail. wing 207. It appears to be very small distributed and genuinely rare, although its nocturnal habits and associated difficulties in identification have probably led to it being overlooked.The sight records were of single, silent birds observed at dusk and dawn: (i)perched on a small branch c.0.5m above the ground at the edge of a road (King 1994); and (ii)sitting on a road in a partially open area on a ridge, (iii) hawking along the forest edge at a height of 1-35m, mainly 5-15m, and(iv)briefly passing at midstorey over a small partially open area (KDB & J.M.Diamond). Flight consisted of sailing on rather flat, rounded wings interspersed with occasional fluttering as the bird presumably attempted to catch flying insects; the tail looked shortish and square; and the eyes reflected yellow in the spotlight.
Although it must have suffered from loss of habitat at lower altitudes, its recent discovery in montane forest suggests that it may be locally secure. It has been recorded in one protected area, Lore Lindu National Park,until now you can find easier in there if you are lucky. August 31’ 2008 we found a pair Satanic Nightjar sleeping on the nest edge street in Heliped Anaso Lore Lindu National Park.
