Hill Swallow

Hirundo domicola

A small dark blue-black swallow with rufous-chestnut on its face and a short tail. Except for a black triangular eye-stripe extending to the bill, the entire forehead, chin, throat, and upper breast are rufous-chestnut, without any dark necklace like that of Barn Swallow, the main confusion species. Hill Swallow’s dark upperparts have a blue-green sheen that is only visible when seen up close, while the underparts are dingy white with ashy-gray on the flanks. Juveniles have duller chestnut on the face. Mainly inhabits open areas such as grasslands, reservoirs, and tea estates in the high hills above 500 meters of elevation; very rare at lower elevations. Often seen wheeling and looping in the air after insects, with a swift flight action reminiscent of a Barn Swallow with a shorter tail.

识别特征

This species is a small swallow at 13 cm (5.1 in). It has a blue back with browner wings and tail, a red face and throat, and dusky underparts. It differs from the barn swallow and the closely related welcome swallow in its shorter and less forked tail.

行为

The hill swallow builds a neat cup-shaped nest, constructed with mud pellets collected in the beak, under a cliff ledge or on man-made structures such as a building, bridge or tunnel. The nest is lined with softer material, and the clutch is up to four eggs. Detailed studies on the breeding ecology of the species were conducted in Silent Valley National Park and Muthikkulam reserve forests of Kerala.<p>It is similar in behaviour to other aerial insectivores, such as other swallows and the unrelated swifts. It is a fast flyer and feeds on insects, especially flies, while airborne.

Fiji Streaked Fantail

Fiji Streaked Fantail

Rhipidura layardi

Small, with a long, often fanned tail. Warm brown overall with a short white eyebrow and variably streaked white underparts; birds on Taveuni have minimal streaking compared to birds elsewhere in Fiji. Found in forest and forest edge, avoiding open areas. Similar to Gray Fantail, but note brown back and heavily marked chest. Song is a short, high-pitched squeaking up-and-down series. Calls include strident “chek!” and nasal scolding calls.

Brown Trembler

Brown Trembler

Cinclocerthia ruficauda

A bright-eyed, hefty billed bird of forests and scrublands. Tends to hold its tail cocked up and wings drooped, especially when feeding. Typically appears almost entirely warm brown; dark above and paler below with some gray on head. Gray Trembler lacks the brown hues of Brown Trembler and has some degree of white below. White-breasted Thrasher has largely bright white underparts and a dark red eye (not yellow as in Brown Trembler). Song is a slow jumble of rich whistles and high-pitched sibilant notes. Calls include scattered whistles and harsh scolding notes.

Dark-backed Imperial-Pigeon

Dark-backed Imperial-Pigeon

Ducula lacernulata

Large gray-brown pigeon with dark brown wings and back. Head color varies across range: a silver-gray head in western Java, a pinkish-buff head in eastern Java, and an intermediate pinkish face and gray crown elsewhere. Widespread, but generally only locally common, roaming extensively through foothill and montane forests. Generally perches quietly in the canopy, often in small flocks. Visits fruiting trees. Gives deep hooting coos: “whuup, whuup.”
