Green Barbet
Cryptolybia olivacea
Chunky olive-green barbet. The head pattern varies geographically, from uniform olive-green, to olive-green with a yellow or buff ear patch, to black with a yellow ear patch. Found in the canopy of lowland and montane forest, often in the vicinity of fruiting trees. Sometimes perches out on dead trees, though otherwise inconspicuous. Call is a repeated, wooden “chak”. Similar overall coloration, but much larger than green tinkerbirds.
识别特征
They have dull ginger-olive plumage, but are yellower on the wings, and paler below. The head and chin are dark brown in the nominate race, and the eyes vary from dull red to orange. The bill is black and the feet blackish. Juveniles are duller, with brown eyes.
分类信息
The number of races (or species) is not generally agreed upon, and the conservation status of the taxa depends critically on their taxonomic evaluation. Race C. o. hylophona is sometimes merged with woodwardi in a taxon with tentative species status, the so-called Woodward's barbet. These birds have the ear coverts and hind brow marked in yellow, as opposed to the dusky-headed populations. The type was obtained from oNgoye Forest in South Africa, and named for its discoverers, the Woodward brothers. C. o. belcheri, which lacks the yellow ear coverts, is endemic to two isolated inselbergs, and may constitute a third species.

Gray-breasted Babbler
Malacopteron albogulare
Smartly-attired babbler of wet lowland and foothills forests. Gray-brown with a sharply contrasting gray-and-white head pattern and off-white belly. Not as social as many other babblers; at most seen in small flocks, and more often seen singly or in pairs. Forages near the forest floor, hopping sideways between branches. Song is a rather hesitant-sounding series of whistles and chirps.
Cinnamon-breasted Tody-Tyrant
Hemitriccus cinnamomeipectus
A small flycatcher found only on several outlying ridges along the eastern Andes in northern Peru and southern Ecuador. It has a cinnamon breast and throat, a yellowish belly, and buffy “spectacles” that can be inconspicuous on some individuals. Inhabits lower to middle levels of stunted cloud forest, where it can sometimes be hard to spot as it flits from one perch to another in the gloom. Calls include a short, downslurred trill and a series of three to seven sharp squeaks.
African Darter
Anhinga rufa
A long and slender cormorant-like waterbird that often swims with its body submerged and only the “S”-shaped neck protruding from the water. Adults are mostly black with white flecks and streaks. Males have a rusty neck and a white stripe running from the eye down the side of the head, which is duller when not breeding. Females and juveniles are muted and brown. African Darter is widespread in freshwater wetlands, preferring placid to fast flowing waters. Cormorants have proportionately larger heads, bulkier necks, and hooked rather than bayonet-shaped bills.
