The Dulit frogmouth (Batrachostomus harterti) is a little-known species of bird in the Podargidae, or frogmouth, family, with a patchily recorded distribution in the mountain forests of northern and central Borneo to which it is endemic. The species is monotypic.
The type specimen was collected by Charles Hose in 1891 on Mount Dulit in northern Sarawak, at an altitude of about 600 m, with the bird being taken “in a small jungle hut into which it had flown in the dusk evidently attracted by the light”. The common name reflects the type locality, while the specific epithet honours German ornithologist Ernst Hartert.
It is a large, dark, chestnut-brown frogmouth, ranging in length from 32 to 37 cm. The wing length is 220 to 250 mm. It has buffish barring on the crown and a narrow buffish collar on the hindneck. The wing-coverts have large white spots. The underparts are paler brown with buff bars and spots. The sexes are similar.
The only other frogmouth of comparable size in Borneo is the large frogmouth (B. auritus), with which the Dulit frogmouth forms a superspecies. The large frogmouth is slightly larger (with a length of 39 – 42 cm) and paler; the crown is spotted and vermiculated rather than barred, the wing-coverts more heavily spotted, and the underparts plainer. No other frogmouth found in Borneo is more than 30 cm in length.
The call is not known for certain, though Tom Harrisson recorded a call in the Kelabit Highlands, which he attributed to this species, as "tuab tuab". The Kelabit name for the frogmouth is Tu’ub or Suit tu’ub.
The frogmouth is endemic to Borneo. Only eight museum specimens are known, taken from Mount Dulit, the Usun Apau Plateau and the Kelabit Highlands in Sarawak, and from Mount Liang Kubung in West Kalimantan. It has also been seen near Poring in the Kinabalu National Park in Sabah.
