Pringle's Puffback

Chunky, long-legged, colorful bird. White shoulder marks are conspicuous in flight. Less shy and more approachable than the other ground-rollers. Found in eastern and northern rainforest and in adjacent scrub. Feeds in the understory, avoiding disturbance by fleeing on the ground or making short flights. Song is a quick “bwuup” note that is repeated slowly, delivered from a perch in the mid-story. Lacks the intricate scaly marks of Scaly Ground-Roller and the rufous head and body of Rufous-headed Ground-Roller. 

A nest parasite that lays its eggs in the nests of Black-cheeked and Black-faced Waxbills. As with other whydahs, breeding males are distinctive, whereas non-breeding males and females are drab and inconspicuous. Breeding males are glossy blue-black with elongated central tail feathers. Non-breeding males and females have a brownish back, a heavily striped face, and a whitish bill and legs. Generally uncommon in rather dry savanna and woodland. Non-breeding male and female can be cautiously separated from other whydahs and indigobirds by their pale bill and legs. Not very vocal, but does imitate the waxbills that it parasitizes. 

A tiny, nearly tailless quail-like bird with a heavy bill, an orange-rufous chest patch, a pale whitish undertail, and dark, heavily streaked, cryptically patterned upperparts. Small groups inhabit native grasslands and scrub in lowlands and on low ridges. Confined to Sumba. Differs from Red-backed Buttonquail in lacking red facial areas, lacking bold spotting along its flanks, showing a whitish undertail, and possessing a stouter gray bill without yellow coloration. In flight, it also shows heavier streaking above than Red-backed Buttonquail. Calls of Sumba Buttonquail are currently unknown.
