Dark-backed Imperial-Pigeon

Small flycatcher that is largely olive above and cinnamon below with a gray head. The bill is two-toned with a pale base. Found in the understory of humid forests, second growth, and forests edges. Males may display in groups giving a low nasal “bayo” song.

A medium-sized wheatear that is variable in plumage, but always has a diagnostic white rump and outer tail feathers in both sexes. The male has both gray and black morphs with white shoulder patches and black wings; gray morphs often have a gray crown. The female is sooty brown. Pairs and small groups perch on promontories in open shrubby hilly areas, stony patches on level ground, and around stone buildings, dropping onto the ground to forage. The similar White-headed Black-Chat resembles male dark-morph Mountain Wheatear, but has a black tail and rump and occupies broadleaf woodland.

A bulky roller that is mostly dull purple-cinnamon in color; it is flecked with many fine white streaks and has a bold white eyebrow. It exposes colorful blue wings and tail while performing an acrobatic rolling flight display. Singles and pairs sit conspicuously in open savanna, preferring thornveld and drier woodlands. It perches on exposed snags and swoops to the ground to hunt large invertebrates and small vertebrates. A partial resident, it also enganges in complicated seasonal movements in parts of its range. The similarly-plumaged Broad-billed Roller is smaller, has a bright yellow (not dark) bill, and prefers moister habitats.
