Oriental Pratincole
Glareola maldivarum
Twisting and turning on long, angular wings, this relative of the sandpipers and plovers gives a swallowlike impression in flight. Adults are brown overall with an elegant black necklace and pale yellow throat. When in flight, note dark flight feathers, chestnut underwing coverts, bright white trailing edge to the wings, and a flashing white rump. Juveniles are a mottled gray-brown above and lack the adult's necklace. Flight call a harsh “tarrack.”
识别特征
These birds have short legs, long pointed wings and long forked tails. They have short bills, which is an adaptation to aerial feeding. The back and head are brown, and the wings are brown with black flight feathers. The belly is white. The underwings are chestnut. Very good views are needed to distinguish this species from other pratincoles, such as the very similar collared pratincole, which also has a chestnut underwing, and black-winged pratincole which shares the black upperwing flight feathers and lack of a white trailing edge to the wing. These features are not always readily seen in the field, especially as the chestnut underwing appears black unless excellent views are obtained.

Hodgson's Redstart
Phoenicurus hodgsoni
Male very similar in appearance to Daurian Redstart; note more restricted silver on the forehead and less distinct wing panel. Female’s lack of a white wing patch distinguishes her from female Daurian, and she averages paler than female Black Redstart, with a brighter eye-ring. Blue-fronted Redstart female can be similar; Hodgson’s female is colder-toned with a single dark stripe down the tail instead of Blue-fronted’s inverted “T.” Hodgson’s breeds in hilly and montane open forests and forest edge; descends in the winter, favoring scrubby edge.
Vanikoro Monarch
Mayrornis schistaceus
A rather chunky flycatcher, mostly dark slate-gray with a pale eye-ring and obvious white undertail. Sometimes cocks and slightly fans tail, especially if aggravated. Dependent on primary forest. Apparently tolerant of old logged areas, but easily disturbed. Voice is a typical scolding “tchatchatcha.”
Imperial Cormorant
Leucocarbo atriceps
Very striking cormorant readily identified by white neck. Locally common black-and-white cormorant of colder coastal waters. Often seen perched on inshore rocks and jetties, sometimes with Magellanic Cormorant. Nests colonially on low islands (rarely in lakes inland from coast) and jetties. Plumage varies regionally, with some birds black-faced and others white-faced; the two types breed together locally in the Strait of Magellan. Immature resembles adult but plumage duller overall, brownish above.
