Orange Ground-Thrush
Geokichla gurneyi
Large, brown-backed, orange-breasted thrush with bold white wingbars. Found in the understory of middle- and high-elevation forest. Generally shy and scarce. The song is musical and typically thrush-like: a chatty and cheerful series of whistles. The call is a very thin, rising trill. Very similar to Abyssinian Ground-Thrush, but has a different pattern on the head: an olive crown, black bar below the eye, and a broken white eye ring.
Identification
Its length is 21–23 cm (8.3–9.1 in). The male weighs 44.5–64.5 g (1.57–2.28 oz), and the female weighs 48.5–76 g (1.71–2.68 oz). The upperparts are olive-brown; some parts have a grey tinge. The flight feathers are blackish-brown. There are two bars on the wing. The throat, breast and flanks are orange. The vent is white. There is an incomplete white eye-ring. The beak is dark. The legs are pink. The female is similar to the male but is less bright. The immature has mottled underparts.
Taxonomy
The orange ground thrush was described as Turdus gurneyi by Hartlaub in 1864. It is named after John Henry Gurney Sr., an English banker, politician and ornithologist. There are five subspecies: G. g. chuka found in central Kenya; G. g. raineyi found in southeastern Kenya; G. g. otomitra found in western Angola, southeastern Democratic Republic of the Congo, Tanzania, and northern Malawi; G. g. gurneyi found in eastern South Africa; and G. g. disruptans found in central Malawi to northeastern South Africa.

Range and habitat
Its habitat is montane forests, namely the afromontane of southeastern Africa. The size of its range is estimated at 5,370,000 km2 (2,070,000 sq mi). It is found at elevations of 500–2,500 m (1,600–8,200 ft).

Behavior
The orange ground thrush is crepuscular. It is sedentary, but makes altitudinal movements in some regions. Its call is tsip and cureek. Its song is a series of several mellow and melodious notes. It feeds on the ground. Its diet is earthworms, insects, molluscs and fruits. The breeding season is January to May in Kenya, August to December in Tanzania, October to January in Malawi, and September to December in Mozambique, South Africa and Zimbabwe. In breeding pairs, the female has been observed to consistently weigh more than the male. The nest is a deep cup built of moss, twigs, leaves, roots and ferns. There are 2 to 3 turquoise-blue eggs. The eggs are incubated for 15 days. The fledging period is 18 to 20 days.

Sooty Ant-Tanager
Driophlox gutturalis
Rather large, chunky tanager endemic to northwestern Colombia. Unlikely to be mistaken. Male isall sooty gray with striking red throat and crest. Female is similar to male but slightly duller. Occurs in the lowlands up to around 1,100 m. Typically seen in pairs or small groups in the understory of forest, often near water. Frequently follows mixed-species flocks.
Taiwan Thrush
Turdus niveiceps
Uncommon endemic thrush breeding in montane forests (1000-2500 m). Male is striking: black with an orange belly and a snow-white head. Female browner, with a brown-and-white-mottled head. Descends into foothills and even lowlands during the winter, when it may mix with other thrush species. Male gives a melodic whistled song from the canopy.
Kadavu Honeyeater
Meliphacator provocator
Upperparts mostly brown with white streaks. Underparts tawny-buff with brown streaks. Has bright yellow bare facial skin and a dark moustache. Found in most habitats, including gardens. Voice is a mix of mellow whistling and ringing calls, often starting with “kee-kow.”
