Tibetan Serin
Spinus thibetanus
Bright yellow finch of foothill and montane coniferous and mixed forests. Male is greenish-yellow above and bright yellow below. Female is less yellow overall and extensively streaked all over her body; can be similar to female or juvenile greenfinches, which are less extensively streaked and have a single large bright yellow panel on the wing. Often perches at the tops of coniferous trees. Forms large flocks in the winter. Gives a variety of calls, including wheezy notes, twitters, and trills. Song is usually a combination of wheezy and trill notes.
识别特征
Length (including the tail) of this species is around 12 cm (4.7 in). The Tibetan siskin lacks yellow panels on its wings in all plumages. Adult males have olive-greenish upper parts, yellow underparts, yellowish-green rumps, yellow supercilium and border behind ear-coverts. Wing and tail feathers of this bird species are broadly differentiated by a yellowish-green color. Adult females of this species have black streaking on darker greyish-green upper parts, more clearly defined wing-bars than their male counterparts, paler yellowish throats and black-flanked breasts with streaking. Juveniles are duller green, tinged brownish-buff on upper parts, with duller rumps, buff fringes to greater coverts and paler or heavily streaked underparts.
分类信息
The Tibetan serin was formerly placed in the genus Serinus but was assigned to the genus Spinus based on a phylogenetic analysis of mitochondrial and nuclear DNA sequences.<p>The first description of the species was by the British ornithologist Allan Octavian Hume in 1872 under the binomial name Chrysomitris thibetanus. In the 19th century, it was also referred to as the Sikkim siskin.At that time, the Lepcha of Sikkim referred to it as tŭk nyil nyón ('fierce wormwood').

This species is found in Bhutan, China, India, Myanmar, and Nepal. Its natural habitat is temperate forests. It spends the winter in the central and eastern Himalayas. A group of birders from West Bengal discovered its presence in Hee Village near Varsey Rhododendron Sanctuary, Sikkim, India in the month of March 2013. Tibetan serins generally breed in mixed forest and spend their winter in alder.

Slaty-backed Thrush
Geokichla schistacea
An unmistakable black, white, and gray thrush. Gray upperparts and black head marked with bold white cheek patch and long white eyebrow. Throat and chest black and belly clean white, peppered with black spots on the upper part. Occurs in forest, where it forages on the ground but often perches in trees just below the canopy, particularly when singing. Confined to the Tanimbar Islands. Complex song is a sequence of melodious whistled stanzas, mostly upslurred at the start, and interspersed with quick “chew-chew-chew” phrases.
Three-streaked Tchagra
Tchagra jamesi
A mostly gray tchagra of dry country. Of the three fine namesake streaks, two run through the eyes and one along the top of the head. The mostly rufous wings and white tail tips are conspicuous in flight. Found in areas of dry savanna and thornscrub with dense undergrowth. Generally uncommon and inconspicuous. Reminiscent of Brown-crowned and Black-crowned Tchagras, but separated by the gray head, which lacks buff eyebrows. The song is a descending series of whistles, often given in a parachuting display flight, similar to the song of Brown-crowned Tchagra, but slightly higher-pitched.
Black-thighed Falconet
Microhierax fringillarius
Dwarfed by shrikes and thrushes, this tiny raptor looks almost parakeet-like as it perches on exposed branches. Coloration distinctive: birds are black above with a white chest and rusty orange belly. Black forehead “earmuffs” are unique among the region’s raptors. Inhabits lowland and foothill forests, where it is generally fairly uncommon. Rather social for a raptor, often seen preening and feeding together in small flocks.
