Common Redshank
Tringa totanus
Stocky brown wader with bright red legs; compare with slenderer, far more gracile Spotted Redshank in juvenile and non-breeding plumage. Often rather wary, alerting other birds with its loud, fluty, whistled calls. Bobs tail when nervous, and then flies to show flashy white trailing edge to wings, white rump patch. Feeds in muddy shallows, probing and picking with its bill. Inhabits fresh and coastal wetlands; also breeds on moorland, usually near water.
识别特征
Common redshanks in breeding plumage are a marbled brown color, slightly lighter below. In winter plumage they become somewhat lighter-toned and less patterned, being rather plain greyish-brown above and whitish below. They have red legs and a black-tipped red bill, and show white up the back and on the wings in flight.<p>The spotted redshank (T. erythropus), which breeds in the Arctic, has a longer bill and legs; it is almost entirely black in breeding plumage and very pale in winter. It is not a particularly close relative of the common redshank, but rather belongs to a high-latitude lineage of largish shanks. T. totanus on the other hand is closely related to the marsh sandpiper (T. stagnatilis), and closer still to the small wood sandpiper (T. glareola). The ancestors of the latter and the common redshank seem to have diverged around the Miocene-Pliocene boundary, about 5–6 million years ago. These three subarctic- to temperate-region species form a group of smallish shanks with have red or yellowish legs, and in breeding plumage are generally a subdued light brown above with some darker mottling, and have somewhat diffuse small brownish spots on the breast and neck.
分类信息
The common redshank was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Scolopax totanus. It is now placed with twelve other species in the genus Tringa that Linnaeus had introduced in 1758. The genus name Tringa is the Neo-Latin name given to the green sandpiper by the Italian naturalist Ulisse Aldrovandi in 1603 based on Ancient Greek trungas, a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific totanus is from Tótano, the Italian name for this bird.<p>Six subspecies are recognised:

分布与栖息地
The common redshank is a widespread breeding bird across temperate Eurasia. It is a migratory species, wintering on coasts around the Mediterranean, on the Atlantic coast of Europe from Ireland and Great Britain southwards, and in South Asia. They are uncommon vagrants outside these areas; on Palau in Micronesia for example, the species was recorded in the mid-1970s and in 2000.A tagged redshank was spotted at Manakudi Bird Sanctuary, Kanniyakumari District of Tamil Nadu, India in the month of April 2021.

Mindoro Boobook
Ninox mindorensis
A fairly small owl of lowland and foothill forest and woodland. Rather dark brown on the head and back and reddish-brown on the chest, with bright yellow eyes and thin white eyebrows forming a V. Mindoro Scops-Owl is similar in size and color, but Mindoro Boobook is finely barred all over. Much smaller than Chocolate Boobook, without white on the chest. Song is a fairly high-pitched, descending mournful whistle, “wiiiiuuuuu.”
Black-rumped Flameback
Dinopium benghalense
A common, “small-billed” golden-backed woodpecker with four toes. Endemic to the Indian subcontinent and Sri Lanka. Associated with every lowland wooded habitat except dense tropical forest, it often follows degradation into higher elevations. Separated from all other flamebacks except Red-backed by dark throat, lack of a contrasting black horizontal stripe below the cheek, and four toes. Separated from Red-backed by golden back and black shoulder. Often detected by its loud “ki-ki-ki-ki-ki,” which steadily increases in pace and ends in a trill.
Red-capped Robin
Petroica goodenovii
Small Australian robin. Male black above, with a black head and chin, vivid scarlet breast and forecrown. Folded wing black with extensive white panels. Female brown above, pale below, with faint reddish forehead and darker wing showing pale panels. Found across much of inland Australia, typically alone or in pairs in more arid environments that other robins in the genus. Hunts by plucking prey from the ground, in typical Australian robin style.
