Marsh Sandpiper
Tringa stagnatilis
Slender pale sandpiper with a fine, needle-like bill. Note the overall slim and elegant shape, with very long and slender greenish legs: suggests a much smaller Greenshank that’s been to ballet school. In flight appears dark above with broad white stripe up middle of back; long legs project well past tail tip. Usually found singly or mixed in with other waders in varied fresh to brackish wetland habitats, usually with open water. Feeds by wading in water, picking with its bill. Repetitive mellow calls somewhat similar to Greenshank, but rather monotone and with a sharper quality.
识别特征
The marsh sandpiper resembles a small elegant greenshank, with a long fine bill and very long yellowish legs. Like the greenshank, it is greyish brown in breeding plumage, paler in winter, and has a white wedge up its back that is visible in flight. However, it is more closely related to the common redshank and the wood sandpiper. Together, they form a group of smallish shanks which tend to have red or reddish legs, and in breeding plumage are generally a subdued, light brown above with some darker mottling, with a pattern of somewhat diffuse small brownish spots on the breast and neck. The length is 22–26 cm (8.7–10.2 in), wingspan is 55–59 cm (22–23 in) and weight is 45–120 g (1.6–4.2 oz).

分布与栖息地
The marsh sandpiper breeds in the Palearctic. It is a migratory species, with a majority of birds wintering in Africa and India, and some migrating to Southeast Asia and Australia. They prefer to winter on fresh water wetlands such as swamps and lakes and are usually seen singly or in small groups.<p>Marsh sandpipers are rare vagrants to North America, with most records in Alaska and California. The first marsh sandpiper recorded in Canada was found on 30 April 2022 in Thedford, Lambton County, Ontario by James Holdsworth, and attracted over a thousand birders from Ontario and Michigan, as well as birders from as far away as Texas and Washington State.<p>The marsh sandpiper is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.

Brown-capped Pygmy Woodpecker
Yungipicus nanus
Small woodpecker of open forest and forest edge. Note size, pale eyes, and broad-striped head pattern. Darkness of the crown varies; palest in northern and peninsular India and darkest in Sri Lanka. Where it overlaps with Gray-capped Woodpecker, note the more “blocky” head pattern, pale eyes, and white-spotted tail of Brown-capped. Gives a short chittering trill that rises and falls quickly.
Cabanis's Wren
Cantorchilus modestus
Small, skulking wren of foothills and lowlands in southern Mexico and Central America. Found in forest edges, second-growth thickets, and brushy fields with cane grass. Heard more often than seen: song relatively short with bright phrases usually repeated a few times in quick succession. Note the bold white eyebrow, whitish breast, rich buffy flanks, and bright rusty tail barred black. Formerly known as Plain Wren.
Small Ground-Finch
Geospiza fuliginosa
A small, widespread Galápagos finch. Bill is longer than it is deep, appears somewhat pointed, and has only a slight curve to the upper edge. Lower edge of bill is mostly straight. Bill size varies among individuals, and not all birds can be accurately identified. Bill is black on breeding male and dull orange on female and nonbreeding male. Male’s plumage is sooty-black; female is brown with paler underparts that are streaked with gray. Medium Ground-Finch has thicker, less pointed bill. Sharp-beaked Ground-Finch has bill that is slightly more pointed and is less rounded on the upper edge. Found in a wide variety of habitats on most islands, but absent from Genovesa, Darwin, and Wolf.
