Dulit Frogmouth Batrachostomus harterti

Large frogmouth of Borneo’s central mountains. Inhabits foothill forest (typically 600–1230 m). Heavyset, with a whiskered face and bright white spots on the wings. Similar Large Frogmouth is generally found at lower elevations; Dulit has broader (as opposed to Large’s sharply triangular) white wing spots, strong pale barring on the throat, and overall darker coloration. Song is a low, resonant, melancholy-sounding “hooooo’m”; call consists of barks, typically given in pairs: “woo’WUP!”.
