Rameron Pigeon
Columba arquatrix
Big, dark pigeon with a gray head, and bright yellow feet, bill, and eye ring. Plain in flight. Found in forest, plantations, and woodland. In most of its range, it is a montane species that is restricted to high and middle elevations. Often in small flocks, especially near fruiting trees. Common vocalization is a raspy “brrruuur” call, usually followed by several series of quick hoots. Separated from all other pigeons in its range by its bright yellow bare parts.
Identification
The adult male African olive pigeon is a large pigeon at 37 to 42 cm (15 to 17 in) in length and a weight of 300 to 450 g (11 to 16 oz). Its back and wings are maroon, with the shoulders heavily speckled with white spots. The underparts are maroon with heavy white spotting, and the head is grey with yellow patches around the eye, and a yellow bill. The neck plumage, used in display, is streaked maroon and white, the underwing and undertail are dark grey, and the feet are yellow.<p>Females are very similar but somewhat duller. Juvenile birds have the maroon and grey replaced with dark brown, the bare parts are a dull greenish-yellow, and the wing feathers have pale fringes. In flight, this pigeon looks very dark. Its flight is quick, with the regular beats and an occasional sharp flick of the wings which are characteristic of pigeons in general. The call is a loud coo coo.

Range and habitat
This is a species of cool, moist forest canopies above 1,400 m (4,600 ft) altitude, although it occurs locally as low as 700 m (2,300 ft). It will use mountain fynbos, second growth, and clearings, and feed on agricultural land when not persecuted.

Behavior
The African olive pigeon builds a large stick nest up to 15 m (49 ft) high in a tree and lays one (rarely two) white eggs. The eggs are incubated for 17–20 days to hatching, and the chicks fledge in another 20 days.<p>The male has a display consisting of deep bows, and a display flight which consists of a climb, wing clapping, and slow glide down.<p>The African olive pigeon feeds on fruit and berries, mainly picked in the canopy, but it will also descend for fallen fruit and prey on insects and caterpillars. In the south of its range, it favours the fruit of a highly invasive plant, the bugweed, Solanum mauritianum. Birds fly considerable distances from their roosts to feeding areas, and young or nonbreeding birds form flocks.<p>Geophagy, which is the act of Earth eating, has been observed in this species. The African olive pigeon has been found to eat clay soil of basic pH and high sodium content. Based on current studies, this is for the purpose of supplementing their diet with minerals and as a pH buffer due to their acidic diet.

Natal Spurfowl
Pternistis natalensis
A medium-size brownish francolin with distinctive yellow nostrils and a bright orange-red bill and legs. The back is mottled brown, and the underpart feathers are edged brown and white, giving it a marbled scaled appearance. Juveniles are similar to adults, with duller legs and bill. It is common in savanna, preferring thicker understory. The call is a loud raucous “kak-kreek” that variably accelerates and decelerates. Red-billed Francolin differs from Natal Francolin by having barred (not scaled) underparts and a yellow eye-ring. Swainson’s Francolin differs from Natal Francolin by having red facial skin and dark blackish legs.
Verditer Flycatcher
Eumyias thalassinus
Beautifully vivid turquoise-blue flycatcher. Adult male has dark lores. Juvenile is duller, with noticeably grayer underparts. Sits upright on exposed perches. Found in lowland and hill forests and forest edges. Song is high and undulating phrase of burry or trilled notes. Most common call is a strident “wheet!”
Gray-crowned Flatbill
Tolmomyias poliocephalus
Small, stocky flycatcher with broad, flat bill. Occupies canopy and midstory of forest edges, gardens, and tall second growth in humid lowlands. Has gray crown, pale yellow underparts, and yellow edgings to wing feathers (but not wingbars). Very similar to a few other species of flycatchers, particularly Yellow-margined and Yellow-olive Flycatchers; best distinguishing features include its pale eye, lack of a yellow patch at the base of the primaries, and voice. Call is a loud, quickly rising whistle: “tuee?”, higher and cleaner than similar calls from species like Brownish Twistwing and Blue-backed Manakin, but not as high as the “twee-twee” of Purple-throated Euphonia.
