American Golden-Plover
Pluvialis dominica
Slender, long-winged plover usually found in relatively dry habitats. Breeding plumage shows black belly and face, white neck sides, and dark back and crown spangled with gold. Note sides and undertail coverts entirely black, but beware females and molting birds can be mottled with some white. Nonbreeding plumage is much drabber; grayish overall with distinct white eyebrow and dark cap. Juveniles are crisp and neatly spangled above, washed with gold on the upperparts. At all seasons, note slender shape and narrow bill to separate from Black-bellied Plover, along with grayish underwing in flight. Extremely similar to Pacific Golden-Plover; American is slightly longer-winged, shorter-legged, and smaller-billed, but these features are difficult to judge. Juvenile American is usually duller than Pacific, especially on the face and neck. Average habitat preferences are important (Pacific Golden and Black-bellied more regular on beaches and mudflats), but much overlap. Range is also important. Breeds on Arctic tundra. Fairly common migrant through central North America, uncommon on East Coast, rare on Pacific Coast. During migration, prefers sod fields, dry mudflats, and pastures; often in small flocks, sometimes mixed with Black-bellied Plover. Winters in South America. Note voice: a plaintive “pleedoo” call.
Identification
Measurements:<p>The breeding adult American Golden-plover has a black face, neck, breast, and belly, with a white crown and nape that extends to the side of the breast. The back is mottled black and white with pale, gold spots. The breeding female is similar, but with less black. When in winter plumage, both sexes have grey-brown upperparts, pale grey-brown underparts, and a whitish eyebrow. The head is small, along with the bill.<p>It is similar to two other Golden-plovers, European and Pacific. The American Golden-plover is smaller, slimmer and relatively longer-legged than European golden plover (Pluvialis apricaria) which also has white axillary (armpit) feathers. It is more similar to Pacific golden plover (Pluvialis fulva) with which it was once considered conspecific under the name "lesser golden plover". The Pacific golden plover is slimmer than the American species, has a shorter primary projection, and longer legs, and is usually yellower on the back.

Range and habitat
The breeding habitat of American golden plover is Arctic tundra from northern Canada and Alaska. They nest on the ground in a dry open area. They are migratory and winter in southern South America. They follow an elliptical migration path; northbound birds pass through Central America about January–April and stage in great numbers in places like Illinois before their final push north. In fall, they take a more easterly route, flying mostly over the western Atlantic and Caribbean Sea to the wintering grounds in Patagonia. The bird has one of the longest known migratory routes of over 40,000 km (25,000 mi). Of this, 3,900 km (2,400 mi) is over open ocean where it cannot stop to feed or drink. It does this from body fat stores that it stocks up on prior to the flight. It is a regular vagrant to western Europe.<p>A comparison of dates and migratory patterns leads to the conclusion that Eskimo curlews and American golden plovers were the most likely shore birds to have attracted the attention of Christopher Columbus to the nearby Americas in early October 1492, after 65 days at sea out of sight of land.

Behavior
This bird uses scrape nests, lining them with lichens, grass, and leaves. At its breeding grounds, it is very territorial, displaying aggressively to neighbors. Some American plovers are also territorial in their wintering grounds.<p>The American golden plover lays a clutch of four white to buff eggs that are heavily blotched with both black and brown spots. The eggs generally measure around 48 by 33 mm (1+7⁄8 by 1+5⁄16 in). These eggs are incubated for a period of 26 to 27 days, with the male incubating during the day and the female during the night. The chicks then hatch precocial, leaving the nest within hours and feeding themselves within a day.<p>These birds forage for food on tundra, fields, beaches and tidal flats, usually by sight. They eat terrestrial earthworms, terrestrial snails, insects, insect larvae, crustaceans, fish, berries and seeds.

Other Birds
Red-headed Bluebill
Spermophaga ruficapilla
Pretty member of the waxbill family that has a massive, conical bill. Males have a black belly and females a spotted one, and both sexes show an all-red head. Found in rainforest, gallery forest, thickets, and secondary habitats. Usually in pairs or small groups, in areas with thick undergrowth, and usually some grass. Sometimes on roads and paths. Vocalizations include a quiet “schpit” call and a rarely-heard whistled song. Similar to Grant’s Bluebill, but separated by all-red head. Male similar to male Black-bellied Seedcracker, but separated by its black tail and its red-and-blue rather than all-blue bill.
Red-billed Tyrannulet
Zimmerius cinereicapilla
Small and rather scarce flycatcher found in disturbed forest on the east slope of the Andes. Yellowish-olive with a gray head and pale throat. Combination of stubby, reddish bill, pale iris, and yellow edges to wing feathers that do not form distinct wingbars help separate it from other small flycatchers. Overlaps with the very similar Mishana Tyrannulet in northern Peru, but Red-billed has a gray (not olive) crown and a different voice. Calls include soft whistles and squeaks, given alone or in a quick series. Typically seen perched high in a tree in a clearing or at forest edge.
Cassin's Vireo
Vireo cassinii
Fairly dull vireo, intermediate between Blue-headed and Plumbeous. Grayish-olive overall, but with yellowish flanks and greenish back. Note white spectacles contrasting with gray head and two whitish wingbars. Breeds in mixed coniferous forests, especially in mountainous areas; winters in Mexico. Often separable from Blue-headed and Plumbeous Vireos by range, but can overlap during migration and winter. Cassin's is less contrasty than Blue-headed, especially between the gray face and whitish throat, and the greenish back blends into the nape and crown. Some birds are best left unidentified.
