Red Collared-Dove
Streptopelia tranquebarica
Medium-sized dove of open spaces with trees and bushes. Male is red with a bluish-gray head and female is brown overall. Both sexes have a dark collar. Female may be confused with other collared-doves, but is smaller with a shorter tail. Often forages in pairs, but may congregate in large flocks, particularly in agricultural fields where seeds have been spilled. Song is a hoarse and muffled-sounding series of three or four hoots.

分类信息
The red collared dove was formally described by the French naturalist Johann Hermann in 1804 and given the binomial name Columba tranquebarica. The specific epithet is from the town Tranquebar, now Tharangambadi, on the Coromandel Coast in southern India. The red turtle dove is now placed in the genus Streptopelia that was introduced in 1855 by the French ornithologist Charles Lucien Bonaparte. The genus name is from the Ancient Greek streptos meaning "collar" and peleia meaning "dove".<p>Two subspecies are recognised:

分布与栖息地
This dove is essentially a plains species, extending to Taiwan and the Philippines but uncommon on the Indonesian archipelago (avoiding rocky foothills), and an Oriental species. There is, however, a summer migration into the broader cultivated valleys of Afghania where it breeds. It is the most common dove throughout Punjab. It is a summer migrant visitor to India, where it is more or less resident. It prefers better-wooded tracts such as canal or roadside tree plantations and avoids extensive desert regions. When they first arrive they are often in small flocks, but they soon split up and start pair formation and breeding.

Eared Grebe
Podiceps nigricollis
Small, compact grebe with thin pointed bill. Breeding adults mostly black with chestnut flanks; look for wispy golden plumes on cheek and peaked head shape. In winter, grayish overall with a dark cap blending into the dark cheek, and a smudgy dark neck. Red eye visible at close range. Breeds on marshy ponds and lakes; during migration and winter, often seen on large lakes, bays, and open ocean. Compare with Horned Grebe, especially in winter. Eared is thinner-necked and smaller-headed, with more peaked crown, darker cheek, and no pale tip on bill.
Drab Swiftlet
Collocalia neglecta
A very small, square-tailed dark swift with a dirty white breast, belly, and base of the undertail. An aerial species, usually seen in flocks in flight over a variety of habitats, including forest. In its limited range within the eastern Lesser Sundas, it only overlaps with one other similar species, White-nest Swiftlet. Drab Swiftlet is smaller, lacking an obvious tail notch, and has white underparts.
Asian Rosy-Finch
Leucosticte arctoa
A dark, thickset brown finch. Males throughout most of the species’ range have black faces and throats, and pink-suffused wings and flanks; the Yakutian subspecies is deeper brown on the wings and has no trace of pink. Females have no pink and are paler on the face and throat than males. Breeds above the treeline in barren rocky areas, but descends into lowlands and foothills during the winter. Often forages in open areas such as beaches and fields.
