Yellow-headed Brushfinch
Atlapetes flaviceps
Oddly colored brushfinch with a limited range in the central and western Andes of Colombia. Plumage is unlike that of any other brushfinch, with mostly yellow head and underparts contrasting with its grayish-olive back, wings, and tail. Some birds have dark patches on the ear and crown. Inhabits cloud forest, and while it usually stays fairly low, it will sometimes ascend to surprisingly high levels. Vocalizations include a short series of sweet chips and a longer, descending cascade of trills and rattles.
识别特征
The yellow-headed brushfinch (Atlapetes flaviceps) is a Near Threatened species of bird in the American sparrow family, Passerellidae. It is endemic to Colombia. The common name is a semi-literal translation of the scientific name, with Atlapetes referring to the brushfinch genus, and flaviceps meaning "yellow-headed". This species has a yellow to dark olive head. The throat, chin, malar streak, lores, eye-ring, and ear patch are bright yellow in any case. The rest of the plumage is yellow with dark olive upperparts, wing and tail. The variation in the head color is not well explained, but it is likely that the olive-headed individuals are females and/or immature birds.

分布与栖息地
This bird was encountered in the La Plata Vieja Valley in Huila Department in 1967, but the only recent records are from the upper Coello River basin in Tolima Department (the Toché River is one of the main tributaries of the Coello River). Namely, it is found between 1,000 and 2,500 meters ASL in Cajamarca, Ibagué and Roncesvalles and perhaps Rovira municipalities, in the upper reaches of the Anaime, Cocora, Combeima and Toché river valleys.<p>It remains locally common in thick secondary vegetation and degraded forest, bordering gallery forest and arracacha (Arracacia xanthorriza) and granadilla (Passiflora species) plantations. The yellow-headed brush finch has been observed to take part in mixed-species feeding flocks together with the common bush-tanager (Chlorospingus ophthalmicus), white-throated tyrannulet (Mecocerculus leucophrys), golden-fronted whitestart (Myioborus ornatus), blue-and-black tanager (Tangara vassorii), blue-capped tanager (Thraupis cyanocephala) and fawn-breasted tanager (Pipraeidea melanonota). It is threatened by habitat loss; most areas in the inter-Andean valleys of Colombia have already been converted to agricultural land. The total population is believed to be at least 250 but not more than 1,000 adult birds.

Tibetan Bunting
Emberiza koslowi
Handsome thickset bunting restricted to a small part of the eastern Qinghai-Tibetan plateau where it inhabits scrubby slopes above the timberline. Unmistakable in its range; no other bunting in the area combines its size, brick-orange back, and gray belly. Male has a striking black-and-white head pattern while female is gray-headed with weak streaking. Song is an unmusical and unremarkable series of high, sharp “pi-pi-pipipew” notes.
Brown Parisoma
Curruca lugens
Remarkably plain brown warbler whose most outstanding features are a finely speckled throat and a white outer tail. Found in the canopy of acacia trees at middle and high elevations. Slow-moving and inconspicuous. Usually seen singly or in pairs. Not very vocal, but does give a simple whistled song and ratcheting calls. Somewhat similar to Garden Warbler, but darker below, with white edges to the tail. Could also be mistaken for female Eurasian Blackcap, but lacks its rufous cap.
Slaty-capped Flycatcher
Leptopogon superciliaris
Small flycatcher with gray cap, black ear patch, and buffy wingbars. Head pattern looks messy. Olive back and pale yellow belly. Most similar to Sepia-capped Flycatcher, but that species has a brown cap (not gray). Also very similar to bristle-tyrants of South America but note buffy wingbars and voice—a commonly heard, explosive “pseek!” sometimes with a sputtering trill at the end. Look for singles or pairs in forests and edges, usually not too high in the trees. Often follows mixed-species flocks.
