Pied Stilt
Himantopus leucocephalus
Large black-and-white shorebird with long straight, needle-like bill, and very long pink legs. Note black hind-neck. Juveniles lacks the black hind-neck and has a dark gray crown. Occurs in small groups or in immense flocks, usually close to water. Makes dog-like yapping calls (think Chihuahua).

The pied stilt grows to a length of about 14 in (36 cm) with a wingspan of about 26.5 in (67 cm). The back of the head and neck, the back and the upper surfaces of the wings are glossy greenish-black. The undersides of the wings are plain black and the remainder of the plumage is white, apart from the tail feathers which are tinged with grey. The long, thin legs are pink and the toes have black claws. The long slender beak is black and the irises and the eyelids are red.

The pied stilt is resident in southern Sumatra, Java, Sulawesi and most of Australia, New Zealand and Papua New Guinea. There are non-breeding populations in Sri Lanka, the Philippines, Brunei, Palau, South Kalimantan, West Nusa Tenggara, East Nusa Tenggara, East Timor and New Guinea. This bird is a vagrant to Japan and Christmas Island.

行为
The pied stilt is a waterbird and feeds in shallow water, probing into the sediment with its beak. It is gregarious, and in New Zealand sometimes forms mixed flocks with the black stilt (Himantopus novaezelandiae). It feeds largely on aquatic insects and on small molluscs. It emits a repeated yelping cry as it flies, and the legs trail behind it, tending to sway from side-to-side.<p>The pied stilt breeds in spring, choosing as a nesting site an area of sand or shingle by an estuary, beside a dried up riverbed, on a flat bit of coast or in a grassy field near the sea. It seems particularly attracted to locations near where the red duck-weed (Azolla rubra) flourishes. It prepares a nest in a shallow depression or in a scrape in the ground where it usually lays four, ovoido-conical eggs. These are yellowish-brown dappled irregularly with dark blotches and spots. The nest is difficult to find as the eggs are well-camouflaged. But the parent birds give away the presence of the nest by mounting into the air and flying in circles, uttering distress cries. The chicks are able to leave the nest almost as soon as they have hatched. They are difficult to detect because their downy plumage is well-camouflaged and they "freeze" when alarmed. A parent bird sometimes feigns a leg injury to draw intruders away from its chicks.

其他鸟类
Painted Bush-Quail
Perdicula erythrorhyncha
Attractive and strikingly marked quail with a red bill and legs. Endemic to peninsular India. Males have a white eyebrow and throat that contrast with overall dark plumage. Mostly found in high altitude grasslands of the Western Ghats in south India; populations elsewhere in the peninsula are poorly known. Rather elusive, but can be seen foraging in small groups by roadsides early morning and late evening. Most often detected by its repeated, high pitched “kri-kri” calls during the breeding season.
Black Jacobin
Florisuga fusca
Large and aggressive hummingbird. Mostly black with white flanks. Boldly patterned tail is white with a black center and a thin black terminal band. Both sexes are similar, but juveniles have cinnamon sides to the throat. Found in a variety of habitats including woodlands, forest edges, and plantations, foraging from the understory to the canopy. Also visits feeders and gardens.
Southern Chestnut-breasted Wren
Cyphorhinus thoracicus
Found at higher elevations than other members of its genus. Shy and uncommon denizen of forest undergrowth from 1,100–2,000 m. Chunky and short-tailed, dark brown above with rich rufous neck and breast. Blue eyering. Sexes alike. Could recall an antbird, but especially note pointier bill with a thicker base. Typically found in pairs or small family groups foraging on or near the ground. More easily heard than seen: song consists of repeated phrases that can have eerie clear notes, infected whistles, or harsher phrases, but is slower and lower-pitched than the songs of other wrens in range. Usually gives the same phrase many times before switching to a new phrase.
