Beautiful Sibia

Striking crested antshrike. Males are black from the crest to the breast, with a spotted white-tipped tail; females have a rusty crown and an all-brown tail. Forages from the middle levels to the understory in deciduous forest, woodland, and shrubby dry forest (caatinga). Sings a series of short nasal notes that decelerates rapidly towards the end. Calls include a clear whistle.

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!”.

Large and black, almost as big as Common Raven. Its namesake brown neck is only visible at close range in specific lighting conditions. Bill is slightly thinner, tail shorter and less wedge-shaped, and the call is less deep and throaty compared to Common Raven. Found exclusively in arid zones where it breeds on cliffs, trees, and pylons. Moves around in pairs or small groups, but may congregate at abundant food sources in larger groups.
