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.
Identification
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.
Taxonomy
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').

Range and habitat
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.

Other Birds
Blue-gray Noddy
Anous ceruleus
A very small, pale gray tern with large dark eyes. Smaller and paler gray than Brown and Black Noddies with slightly more of a forked tail. Nests on rocky sea cliffs on tropical islands, typically foraging close to shore, fluttering close to the water and plucking food from the surface in small flocks. Voice is a distinctive nasal “kearr.”
Mossy-nest Swiftlet
Aerodramus salangana
One of a number of essentially identical-looking small swifts. Best identified by its nest, made up of dried moss and other scraps of vegetation; compare with the dark nest of Black-nest Swiftlet and white nest of Edible-nest Swiftlet, with which it often shares its breeding caves. Often flies in large flocks over forests and waterways; mixes with other swiftlets.
Lineated Woodpecker
Dryocopus lineatus
Large ‘woody woodpecker’ of tropical forest in lowlands and foothills. Also ranges into semi-open areas with tall trees, mangroves, and other lightly wooded habitats. The tufted red crest and black face distinguish it from adult Pale-billed Woodpecker, which often occurs in the same areas. Also note that the white ‘braces’ on the back of Lineated are widely spaced, unlike Pale-billed. Laughing call suggests a flicker, and very unlike calls of Pale-billed.
