Xingu Scale-backed Antbird
Willisornis vidua
Small antbird with a short, white-tipped tail. Males are gray on the head and body, including the throat; black back is lined with rows of bold white scales. Females have an unmarked brown back, gray sides to the head and underparts, and a white throat. Inhabits the understory of humid forests. Usually found in pairs; sometimes joins mixed-species flocks and often attends army-ant swarms. Sings an ascending series of about ten quavering “tweet” notes, each note increasing in pitch.

Dunn's Lark
Eremalauda dunni
A chunky, large-billed lark of desolate sandy deserts and open arid plains in northern Africa. Plain sandy-brown above and paler below, with faint and indistinct white markings on the face. Also note the pinkish bill and the inky black outer tail feathers, most apparent in flight. Runs about on the ground, stopping abruptly. Found singly or in pairs when breeding, gathering in larger groups only during the non-breeding season. The song is a sequence of whistles and dry notes, given both from the ground and in song flight. Generally similar to other dry-country larks such as Desert Lark, Bar-tailed Lark, and Kordofan Lark, but combination of unmarked upperparts, black outer tail feathers, and the uniformly pink and bulbous bill is diagnostic.

Böhm's Flycatcher
Myopornis boehmi
Distinctive, chunky flycatcher of miombo woodland. The upperparts are rich brown and the underparts are white with bold triangular spots. Generally uncommon and local in the mid-story of miombo broadleaf woodland. Often joins mixed-species feeding flocks. The quiet song consists of a series of scratchy notes.

Sooty Swift
Cypseloides fumigatus
Medium-sized, uniformly dark-brown swift with sickle-shaped wings and a square-tipped tail. Similar to Great Dusky Swift with which it is sometimes seen, but it is smaller and darker. Breeds and roosts at waterfalls and forages over nearby forests and savannas.
