Piping Hornbill

A huge ground-dwelling hornbill. Males have a mix of blue and red bare facial skin, while females have entirely blue facial skin. In flight, a large white patch is revealed in the wings. Found in savanna, grassland, and agricultural habitats, usually in pairs or small groups, walking on the ground. Breeds and roosts in trees. Similar to Southern Ground-Hornbill, but there is little overlap in range, and Abyssinian is easily separated by the blue facial skin. The call is a series of deep “boop” notes. 

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!”.

Mid-sized, generic-looking warbler-like bird. Males have a glossy blue-black back, a white wing patch, and pale yellowish underparts. Females are similar, but more gray-brown on the back. Found in savanna with broadleaf trees, including miombo and Guinea savanna. Usually in pairs or small groups, which will join mixed-species feeding flocks. The quiet vocalizations include chatty calls and trills. Very similar to Southern Hyliota. In most of the range, Yellow-bellied males distinguished by the longer white patch on the wing, and females by their grayer upperparts. In Uganda and Kenya, males are extremely similar, but Yellow-bellied can still be recognized by its more glossy blue-black back.
