Ahanta Spurfowl

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!”.

A large, chunky sparrow with a bright rufous rump and different-looking males and females. The male has a grayish crown with a rufous crescent around the ears and a white patch between the top of the eye and the base of the bill. The female has a paler washed-out head. Pairs and small groups are loyal to arid thorn scrub, avoiding human-altered habitats. The smaller House Sparrow is most easily told from the Great Rufous Sparrow by having a gray (not rufous) rump.

Large, lumbering shearwater. Diagnostic yellow bill is often visible from quite a long distance. Look for warm pale brown upperparts and clean white belly and underwings. Also note little contrast between the brown head and white throat (compare with distinct capped appearance of Great Shearwater). Lazier wingbeats than other large shearwaters, especially in calm conditions; wings look crooked with wrists pushed forward in flight. Forms mixed flocks with other shearwaters, especially when feeding. Fairly common in warm water in the Atlantic Ocean; increasingly frequent in cooler water, ranging further northward in recent years. Very similar to closely related and recently split Scopoli’s Shearwater. Can be identified with caution, and often by analysis of photographs, by the solidly dark outer part of the underwing.
