Abyssinian Ground-Thrush
Geokichla piaggiae
Large, brown-backed, orange-breasted thrush with bold white wingbars. Found in the understory of montane forest. Generally shy and scarce. The song is a musical and typically thrush-like, a chatty and cheerful series of whistles and chuckles. The call is a very thin, rising trill. Very similar to Orange Ground-Thrush, but has a different pattern on the head: an orange crown, a plain face, and a complete white eye-ring.
识别特征
The Abyssinian ground thrush is an attractive but rather secretive species. The adults are a deep rufous orange on the head and face with a distinct white eye ring, the orange colour becomes les rufous on the breast and flanks and the upperparts are olive brown except for the orange-brown rump and tail. On the folded wing it shows two prominent white wingbars from the tips to the coverts. Immature birds tend to be paler and duller than the adults. They measure 19–20 cm (7.5–7.9 in) in length and weigh 43–65 g (1.5–2.3 oz).<p>The contact call of the Abyssinian ground thrush is a high pitched "tseep", the song is a typical thrush like melodious series of whistled phrases rendered in Sinclair & Ryan as "chee-cheeleeroo-chruup".
分类信息
This thrush has been placed in the genera Turdus, then Zoothera but is now placed in the Geokichla. In addition the subspecies G.p. tanganjicae and G.p kilimensis have sometimes been regarded as separate species but they do not differ very much from the other subspecies in voice or morphology and most authorities lump them with Abyssinian ground thrush.

分布与栖息地
The Abyssinian ground thrush occurs in the undergrowth of evergreen montane forest in high rainfall regions between 1,800 and 3,300 m (5,900 and 10,800 ft), mostly above 2,500 m (8,200 ft), although occasionally found lower. It may also occur in bamboo forest, e.g. on Mount Kenya, or in exotic pine plantations in Ethiopia.

Bat Hawk
Macheiramphus alcinus
An acrobatic, swift-like raptor with angular wings and a massive gape; capable of snatching prey from the air and devouring it in a flash while still on the wing. Dark with varying amounts of white on the underside; African birds have patchy white throughout the underparts, while white is restricted to the throat and lower belly on New Guinean birds and solely to the throat in Southeast Asian birds. Inactive during the day; hunts at dawn and dusk, and occasionally into the night if light is sufficient. Generally uncommon and localized, most reliably encountered near large bat roosts in forested areas, but can also be seen over open forest, fields, and fringes of habitation.
Gold-ringed Tanager
Bangsia aureocincta
Beautiful tanager restricted to Colombia’s western Andes. It is one of the country’s most sought-after endemic birds due to its unique plumage and scarcity. Yellow head crescent, mustache, and breast patch stand out conspicuously against its otherwise black, olive, and blue color pattern. Females and young birds are duller than adult males. Inhabits wet cloud forest, and sometimes joins mixed species flocks. Often perches on an exposed branch, repeatedly giving a burst of sharp notes that rises and then falls.
Orange Oriole
Icterus auratus
Attractive orange-and-black oriole of the Yucatan Peninsula, found in brushy woodland, forest edge, and semi-open areas with hedges and scattered trees. Rather similar to local population of Hooded Oriole, which often occurs in the same areas, even in the same flocks at flowering trees. Male Orange Oriole has an orange back, and both sexes have a straight bill (not slightly decurved, as on Hooded), and a less extensive black face and throat mask than Hooded.
