Varied Tit
Sittiparus varius
Active and colorful inhabitant of temperate lowland and foothill forests. Combination of bright orange underparts, blue-gray wings, and white cheeks is unmistakable within its range; similar Chestnut-bellied Tit is is restricted to Taiwan. Tame and boisterous, often frequenting gardens, parks, and backyard feeders, particularly in the winter.

The varied tit is 12–14 cm (4.7–5.5 in) long and weighs 16–18 g (0.56–0.63 oz). The wing length is 6.0–7.8 cm (2.4–3.1 in). In the nominate race S. v. varius the crown, the bill, the throat, the upper breast and the nape are black. Forehead, face, and cheeks are white. Back, wings, and tail are bluish grey. Mantle, lower breast, belly and undertail coverts are chestnut coloured. From the crown to the nape runs a thin white central line. The feet are dark grey.<p>Its habitat consists of open mixed forests, in particular with the Japanese Castanopsis species Castanopsis cuspidata and Japanese larch, coniferous forests with Japanese yews, Cryptomeria (sugi), and pines as well as bamboo forests at mountain slopes and in river valleys.<p>The varied tit eats a mixed diet consisting of seeds and insects, namely caterpillars.<p>Its call consists of tiny tones which sounds like tzu….tzu….tzu…
分类信息
The varied tit was described by the Dutch zoologist Coenraad Jacob Temminck and the German ornithologist Hermann Schlegel in 1845 and given the binomial name Parus varius. Until the end of the twentieth century the varied tit was usually placed along with most of the other member of the tit family in the genus Parus. In 2005 the report of a molecular phylogenetic study that examined mitochondrial DNA sequences from members of the tit family, recommended including the varied tit along with around fifteen other species in the resurrected genus Poecile. The authors of a 2013 study that analysed both mitochondrial and nuclear sequences, suggested splitting Poecile and placing the varied tit and its sister taxon, the white-fronted tit in their own genus Sittiparus. The genus had originally been erected by the Belgium politician and naturalist Edmond de Sélys Longchamps in 1884 with the varied tit as the type species. This proposal was adopted by the International Ornithologists' Union.<p>Owston's tit (Sittiparus owstoni), the Iriomote tit (Sittiparus olivaceus) and the chestnut-bellied tit (Sittiparus castaneoventris) were formerly considered as subspecies of the varied tit, but were promoted to species status following the publication of a phylogenetic study in 2014.<p>A number of subspecies have been described, of which one has become extinct in the 20th century:

Luzon Racquet-tail
Prioniturus montanus
A medium-sized parrot of montane forest on Luzon. The two central tail feathers have extended shafts ending in a racket shape. Overall green in color, darker on the back and paler below. Male has a blue face and a red crown. The similar Green Racquet-tail may overlap geographically, but Luzon is usually found at higher elevations and has a darker back. Voice includes various grating calls and shrill squeals.
Tepui Toucanet
Aulacorhynchus whitelianus
Small green toucan of tepui highlands; unique in range. Appears slender and small-billed with mostly green plumage contrasting with reddish bill and chestnut tail feather tips. Found in mossy highland forest, generally above 800 meters, where groups move through canopy searching for fruit; sometimes moves with other bird species and will congregate around fruiting trees. Not particularly vocal and surprisingly easy to overlook. Call is a wailing grunt, given in a rhythmic series, sometimes for extended periods with short breaks; it is unlike any other bird vocalization in this species’s limited range.
Hume's Treecreeper
Certhia manipurensis
Physically almost identical to Sikkim Treecreeper, but throat pale tan-orange instead gray. Bright contrasting rusty tail distinguishes it from other treecreepers in its range. A species of foothill to montane and submontane regions; averages lower in elevational range than Sikkim Treecreeper, with minimal to no range overlap. Favors broadleaf evergreen and mixed forests. Occasionally found in mixed-species flocks. Song is slower than that of Sikkim Treecreeper, a rather slow ringing trill composed of paired notes; calls include an echoing two-note “tsijew” and a high “tzit.”
