Magellanic Oystercatcher
Haematopus leucopodus
A boldly patterned large and chunky shorebird of southern South America and Falklands. Favors rocky coastlines and adjacent river mouths, but also frequent on nearby grasslands and lakeshores. Associates readily with other oystercatchers. Told from American Oystercatcher by its glossy black head and upperparts that lack the white shoulder spur. In flight the distinctive upperwing pattern with big white panel on trailing edge separates it from American. At close range, also note the yellow eyering (red on American). Voice is also very distinct from other oystercatchers.
识别特征
The Magellanic oystercatcher has a length between 42 and 46 cm (17 and 18 in). The male weighs around 600 g (21 oz) and the female is a little heavier. This bird has a long, orange beak, yellow eye and eye ring, and yellow legs. The head, breast, back, wings and tail are black and the underparts are white, as are the feathers on the inner part of the wing which can be seen in flight. It is very similar in appearance to the American oystercatcher (Haematopus palliatus), but can be distinguished by the yellow ring of bare skin that surrounds its yellow eye and the white secondary feathers. No other species of oystercatcher has these two features, and it is also the only New World species to have a black rather than a brown back. The call is similar to other oystercatchers, a repeated high-pitched "pee-pee".

分布与栖息地
This species is native to the southern tip of South America. Its range includes southern Argentina, Tierra del Fuego and other nearby islands, and the Falkland Islands. It is present on South Georgia and the South Sandwich Islands but its status there is unclear. It breeds inland on upland grasslands but lives on the coast outside breeding season.

行为
When inland during breeding season, the Magellanic oystercatcher feeds largely on earthworms and insect larvae, probing soft ground and mud with its sharp beak. At other times of year when at the coast it forages for mussels and limpets and feeds on crabs and polychaete worms.<p>When disturbed near the nest it engages in several strategies to divert attention from its eggs and chicks. These include false-brooding, when it moves to sit on an imaginary nest site, and tail-flagging, a ritual aggressive display involving raising tail and wings. It also has a distinctive peeping call to warn off intruders.

Oriental Skylark
Alauda gulgula
Chunky brown songbird with a weak crest, typically found on the ground in open fields and meadows. Darker above than below, with fine black streaking on the chest and light chestnut ear coverts with dark border. Very similar to Eurasian Skylark, with which it shares much of its range, but Oriental has buffy, not white, outer tail edges and trailing edge of wing. Breeding males “skylark,” singing a series of variable notes while hovering high above the territory.
Luzon Striped-Babbler
Zosterornis striatus
A fairly small bird of lowland and foothill forest and overgrown disturbed areas on Luzon. Rufous-brown on the wings, back, and tail, with a gray head, heavily-streaked pale underparts, and a black face and moustache stripe. Often found in mixed-species flocks. Somewhat similar to Stripe-sided and Long-billed Rhabdornises, but smaller, with a white eye-ring rather than a black band through the eye. Voice includes a loud rattling trill and various quiet chips and squeals.
Philippine Swiftlet
Aerodramus mearnsi
Uncommon dark swiftlet. Endemic to a smattering of the Philippines islands, from Luzon to Mindanao to Palawan. Habitat can be helpful in identifying this confusing species; generally favors ridges and slopes in montane and submontane areas above 700-800 meters. Readily confused with significantly larger Ameline Swiftlet, but present species has a more squared-off-looking tail (fork is shallow and often unnoticeable), tends to fly lower and more erratically, and more often forms flocks. Combination of dark rump, unglossed dark back, and medium size separates this species from Gray-rumped Swiftlet, Pygmy Swiftlet, and Ridgetop Swiftlet. Frequently calls while in flight, giving a squeaky chattering twitter.
