Large, upstanding plume of hair-like feathers on the forehead, lores and ear coverts black with 3-4 long, dirty white plumes from the rear of the eye. Median and greater wing coverts spotted whitish with a thin black margin at the tip, primaries speckled buff ( only on the outer webs ? ). Uppertail somewhat paler than the rest of the upperparts with c. 7 tawny bars thinly margined blackish.

Endemic to the mountains of north and central Borneo.
Only known from Gunung Dulit and the Usun Apau plateau in Sarawak, Kelabit Highlands on the borders of Sarawak, Sabah and Kalimantan and Gunung Liang Kubung in Kalimantan Burat.
This is a monotypic species.
Submontane moist forest between 300 and 1700 m.
Probably the same as other Batrachostomus Frogmouths, as are it's food preferences, but little, if anything. is known of its habits.
Voice unknown, but recordings made within the areas where Dulit Frogmouth is known to be found sound similar to Large Frogmouth, a species that is found at much lower altitudes.
