Vietnamese Greenfinch
Chloris monguilloti
A flashing vision in midnight black and daffodil-yellow with a deeply forked tail. Male averages darker than the female with a solid black back and dark streaking on the breast. Female has a patchier back and thinner streaks than the male. Both sexes have a dark head, a thin yellow collar, and bright wing panels. Inhabits foothills and mountainous pine forests and adjacent edges. Favors the Khasi pine where it can be found foraging in small flocks. Gives dry twitters and a typical finchlike wheezy upswept note. Song is usually a series of dry, “ticking” trills followed by an upswept note.

The Vietnamese greenfinch is 13.5 to 14 cm (5.3 to 5.5 in) in length and weighs between 15 and 16 g (0.53 and 0.56 oz). It has a large conical bill, a black head and a narrow bright yellow collar. The plumage of the female is similar to that of the male but is less brightly coloured.
分类信息
The first formal description of the Vietnamese greenfinch was by the American ornithologist Jean Théodore Delacour in 1926 under the binomial name Hypacanthis monguilloti. In the past the greenfinches were placed in the genus Carduelis but when molecular phylogenetic studies found that they were not closely related to the other species in Carduelis, they were moved to the resurrected genus Chloris. The genus had been first introduced by the French naturalist Georges Cuvier in 1800. The word Chloris is from the Ancient Greek khlōris for the European greenfinch; the specific epithet was chosen to honour Maurice Antoine François Monguillot, the General Secretary of French Indochina. The species is monotypic.

分布与栖息地
The Vietnamese greenfinch is native to the Đà Lạt Plateau in southern Vietnam. It is inhabits open montane pine forest of Pinus kesiya, along with forest edges and secondary growth, from 1,050 to 1,900 meters elevation, although it has been recorded as low as 600 meters elevation. It feeds on the seeds of pine trees, and has been observed flycatching recently-hatched termites.

Flammulated Treehunter
Thripadectes flammulatus
Uncommon medium-sized brownish bird of Andean montane forest from Venezuela through Ecuador and just barely into Peru. Distinctive among treehunters with its bold buffy streaking covering the entire head, back, and body. Rufous wings and tail. Sexes alike. Usually found singly or in pairs moving furtively through the understory of forest, often around bamboo, from around 2,200–3,500 m. Does not typically follow mixed-species flocks.
Katanga Masked-Weaver
Ploceus katangae
This red-eyed masked-weaver has a plain olive-green back and pink-brown legs. The breeding male has a black face mask, with the black band on the forehead above the bill varying from broad in the south to narrow farther north. Female and juvenile are dull and inseparable from other masked-weavers. Pairs and colonies are localized residents of reedbeds, wetlands and adjacent woodland, in a narrow global range between northeastern Zambia and southeastern DRC. The breeding males of Katanga and Southern masked-weavers are very similar, but the former are smaller, have some saffron around the masks, and have darker green backs and rumps; breeding male Tanganyika and Lake Lufira Masked-Weavers have more burnt-orange around the face and underparts, and ranges do not overlap.
Plain-winged Antshrike
Thamnophilus schistaceus
Even-colored antshrike of forest under- and midstory. Often travels with mixed-species flocks. Males are plain gray; females are tawny with olive underparts. Females have a more contrasting reddish cap than other female antshrikes. Heard more often than seen; listen for a series of accelerating “awh” notes terminating in a punctuated down-slurred note.
