Whiskered Flycatcher
Myiobius barbatus
Small flycatcher with big eyes, prominent facial bristles, and a yellow spot on the crown, which is usually concealed. Note the yellow rump contrasting with a gray-brown back. The throat is whitish and the belly yellowish. Several different subspecies occur that vary in the strength of the tawny coloration on the breast. Occupies the lower and middle levels of humid forests where it usually accompanies mixed-species flocks. Not a very vocal species, but it has a “tsip” call, which can be mistaken for an insect.
识别特征
The whiskered myiobius is very similar in appearance to several closely related species. It has olive upper parts, an obvious yellow rump and a usually well-concealed yellow patch on the crown. The rictal bristles round the beak are long and form a basket-like structure. The underparts are greyish-olive and the belly pale yellow. The tail is black and somewhat rounded. It is usually a silent bird, but sometimes utters a staccato "psik".
分类信息
The whiskered myiobius was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the flycatcher in the genus Muscicapa and coined the binomial name Muscicapa barbata. The specific epithet is from the Latin barbatus meaning "bearded". Gmelin based his description on "Le barbichon de Cayenne" that had been described in 1778 by the French polymath the Comte de Buffon and illustrated with a hand-coloured engraving by François-Nicolas Martinet. The whiskered myiobius is now one of four species placed in the genus Myiobius that was erected in 1839 by George Gray.<p>Five subspecies are recognised:

分布与栖息地
The species is widely distributed in tropical South America. It is found in the Amazon basin in the northern half of Brazil, northeastern Peru, eastern Ecuador, eastern Colombia, southern Venezuela, Guyana, Suriname and French Guiana. Its typical habitat is the lower parts of the canopy of humid rainforest at altitudes of less than 900 m (3,000 ft). It is more often found in the middle of forests than is the black-tailed myiobius (M. atricaudus), and in Amazonia occurs at lower elevations than the tawny-breasted myiobius (M. villosus).

行为
Like other myiobius, the diet consists largely of insects, many of which are caught aerobatically on the wing. It often forages in small mixed flocks. When perched, this bird often droops its wings and fans the feathers of the tail in a manner reminiscent of Old World fantails (Rhipidura).

Village Indigobird
Vidua chalybeata
Nest parasite that lays its eggs in the nests of Red-billed and Brown firefinches. Breeding males are glossy black, while females and non-breeding males are streaky and brown on the back and pale below, with a bold facial pattern. The color of the bill is red in southeast Africa and whitish in western, northern, and central Africa. Found in savanna, scrub, farmland, and towns. Mimics the vocalizations of its host firefinches: low rattling series and high-pitched whistled notes. In southeast Africa, can be separated from other indigobirds by its red bill. Very similar to other indigobirds elsewhere on the continent. Breeding males can be separated by their all-black wings that lack a pale brownish panel. The mimicked vocalizations of its host species can also help confirm identification. In non-breeding plumage, similar to non-breeding Pin-tailed Whydah but separated by red legs.
Ashy-bellied White-eye
Zosterops citrinella
Small songbird with bright yellowish upperparts and white “goggles.” Most subspecies have gray underparts; subspecies “unicus” of Sumbawa and Flores has a yellow belly. Compare with other white-eyes in various parts of their range; note present species combination of dark iris and yellow back. Inhabits a wide range of different wooded habitats across its range, including coastal scrub, mangroves, inland forests, and forest edge. Forages actively in small to medium-sized flocks, sometimes mixing with other species. Can be quite common on small islands. Twittering song is bright but unremarkable. Most frequently given call is a somewhat variable high-pitched, descending “djee.”
Richard's Pipit
Anthus richardi
Large, robust, almost thrushlike pipit given the big bill, long and pale eyebrow, and long tail. If perched off the ground the very large hind claws and long legs are obvious. Flight is strong, heavy, and bounding. Utters "pshee" call when flushed. Found in open grasslands, stubble fields, farmland, dunes, and salt marshes. Separation from other large pipits can be difficult; pay attention to call and wing pattern.
