Wire-tailed Swallow

Hirundo smithii

A very distinctive swallow with two long, thin feathers on its outer tail from which it gets its name. It has brilliant glossy blue upperparts and a chestnut forehead and crown that contrasts with clean white underparts. Females and juveniles have shorter tails. Found in grasslands, wetlands, open scrublands, cultivated areas and near water. Typically seen in singles, pairs, or sometimes small flocks.

识别特征

The wire-tailed swallow is a small swallow, measuring 18 cm (7.1 in) in length. It has bright blue upperparts, bright white underparts and a chestnut cap. Immature birds lack tail wires, and have dull brown (rather than chestnut) caps. The species is named for the very long filamentous outermost tail feathers, which trail behind like two wires. The sexes are similar in appearance, but the female has shorter "wires". Juveniles have a brown crown, back and tail. The Asian form, H. s. filifera, is larger and longer-tailed than the abundant African H. s. smithii.

Sumba Hornbill

Sumba Hornbill

Rhyticeros everetti

A small black hornbill with an ivory-colored bill that has a reddish smudge at the base and a knob on top. There is a pale blue pouch of skin below the bill. Males have a rich chestnut neck that becomes a darker burnt red around the face and top of the head. Females have black necks and heads. Juveniles resemble male, with a smaller bill. Confined to Sumba, where it is the only hornbill. Inhabits lowland and foothill forest and forest edge, where it frequents the treetops singly or in groups. Calls include a fast-paced, emphatic “kokokokokokok…”.

Malabar Flameback

Malabar Flameback

Chrysocolaptes socialis

A large, crested woodpecker with a golden-olive back endemic to wet lowland and foothill forests in southwestern India. Separated from Common Flameback and other “small-billed” flamebacks by a much larger bill, a mottled black-and-white nape instead of a black nape, and a divided black horizontal stripe below the cheek. Separated from the similarly large-billed White-naped Woodpecker by the less clean-cut face pattern, a red rump, the lack of a clean white nape, and a preference for wetter habitat. A loose participant in mixed-species foraging flocks, often detected by its loud, high-pitched trill similar to that of Common Flameback.

Brown-cheeked Fulvetta

Brown-cheeked Fulvetta

Alcippe poioicephala

An unapologetically drab and unmarked fulvetta, often seen in association with mixed-species foraging flocks. Brown with a gray wash to the head; Southeast Asian birds have a thin black brow line that Indian birds lack. Lacks the bright white eyering and more prominent brow stripe of Nepal and Yunnan Fulvettas. Inhabits hill and montane forest, where it forages actively in forest and forest edge. Song consists of a brief or mid-length phrase of pleasant-sounding whistles, usually with a short ascending note toward the end. Calls include loud sputtery chattering and rattling.
