Finsch's Imperial-Pigeon
Ducula finschii
A relatively plump and squat imperial-pigeon with a deep chestnut underside, a bright green back and wings, a pale pinkish chest, a gray neck, and a white eye-ring. White tail band sandwiched between two black tail bands is diagnostic. An unobtrusive pigeon that often sits motionless in the canopy of old-growth forest. Rarely seen flying above the canopy. Juvenile Red-knobbed Imperial Pigeon could cause confusion, but lacks the bold tail pattern. Voice of Finsch’s little known, but the species has been heard giving a long gruff coo reportedly similar to a steam engine’s whistle.

White-backed Duck
Thalassornis leuconotus
A smallish, tawny, bulbous-headed duck that sits low in the water, its tail often flush with the surface, giving it a distinctive appearance. When seen well, the white patch at the base of the bill is diagnostic. The namesake white back is usually visible only in flight. Partially nomadic; small groups are found on pans and pools that have emergent aquatic vegetation, especially waterlilies. Mostly quiet; rarely gives a squeaky-toy-like “swit-swit” whistle.
Gray-breasted Spurfowl
Pternistis rufopictus
A large gray-and-brown francolin with bare red skin on the throat and around the eyes. Also note the red bill, the dark gray legs, and the chestnut, buff, and black markings along the sides of the belly. Pale patches in the outer wings are conspicuous in flight. Found in fairly dry thorn savanna, woodland, and thickets, usually in pairs or small groups. Similar to Red-necked Francolin, but there is little overlap in range, and separated by the brown legs and many plumage details. Also similar to Yellow-necked Francolin, but easily separated by the red or sometimes orange (rather than yellow) throat. The call is a fading series of grating “kreaaak” notes.
White-rumped Tanager
Cypsnagra hirundinacea
An unmistakable medium-sized tanager with a black back, a white rump, and two white wingbars. Note the rusty throat and sides. Inhabits grasslands with scattered trees. The noisy song, which is usually delivered in a duet consists of melodic whistles; “whew chid-di-di-wee-wee-tyóó chid-d-o-wóó chi-d-dee-tyóó.”
