Palm Warbler
Setophaga palmarum
Subtly patterned brown-and-yellow warbler, known for constantly bobbing its tail. Often forages on the ground, unlike most other warblers. Breeding plumage shows a rufous cap. In fall and winter, look for pale eyebrow and dark line through the eye, diffuse streaks on underparts, and bright yellow undertail coverts. Two populations: “Western” is browner overall, brightest on the undertail coverts; “Yellow” is more suffused with yellow overall; they overlap extensively in range, especially during fall migration. Breeds in bogs and clearings in the boreal forest. In migration, found in a variety of open, shrubby habitats. One of the more common warblers wintering in the southern U.S.; also winters in the Caribbean and Yucatan Peninsula.

分类信息
The species comprises two distinct subspecies that may merit specific status.<p>"Yellow palm warbler" or "eastern palm warbler" (S. p. hypochrysea) of the eastern third of the breeding range has brownish-olive upper parts and thoroughly yellow underparts with bold rufous breast and flank streaking. It migrates later in the fall than its western counterpart.<p>"Brown palm warbler" or "western palm warbler" (S. p. palmarum) inhabits the remaining western two-thirds of the breeding range. It has much less yellow below, with less colorful streaking, and cold grayish-brown upper parts.

分布与栖息地
Palm warblers breed in open coniferous bogs and edge east of the Continental Divide, across Canada and the northeastern United States.<p>These birds migrate to the southeastern United States, the Yucatán Peninsula, islands of the Caribbean, and eastern Nicaragua south to Panama to winter. They are one of the earlier migrants to return to their breeding grounds in the spring, often completing their migration almost two months before most other warblers. Unlike most Setophaga species, the palm warbler's winter range includes much of the Atlantic coast of North America, extending as far north as southern Nova Scotia. Every year since 1900 the palm warbler has been observed during Christmas Bird Count activities in Massachusetts, and consistently since 1958 in Nova Scotia. For the interval 1966–2015 the palm warbler population increased throughout much of its northernmost breeding range.<p>The palm warbler has been recorded as a vagrant to Iceland.

行为
Palm warbler nests take the form of an open cup, usually situated on or near the ground in an open area.<p>Palm warblers forage on the ground much more than other warblers, sometimes flying to catch insects. These birds mainly eat insects and berries. Their constant tail bobbing is an identifying characteristic. Kirtland's, prairie, and palm warblers are the only Setophaga species that incessantly bob their tails.<p>The song of this bird is a monotonous buzzy trill. The call is a sharp chek.[1]

Buff-tailed Coronet
Boissonneaua flavescens
Medium-sized hummingbird, mostly dark green with obvious buffy underwing and mostly buffy tail. Fairly short, straight bill. Sexes similar. Found in cloud forest from Venezuela to Ecuador, mostly from 1,500–2,400 m. Usually forages in middle to upper levels of trees. Visits feeders, where it aggressively defends its territory against other hummingbirds.
Dapple-throat
Arcanator orostruthus
Supreme understory skulker in montane forest, resembling a hybrid between a thrush and babbler. A dull and dowdy understory specialist with brown-olive upperparts and boldly-streaked cream-yellow underparts. Immature is more uniformly olive. Singles or pairs are highly localized residents working the leaf-litter in rich wet undergrowth of Eastern Arc montane forest, between 900–1800m, especially close to streams; shy and hops or runs quickly across forest-floor, seldom permitting absorbing looks. Vocalizations are variable, but most frequently utters a rich and fluty song “we-lu-we-lu-wel’li-lu” and sweet bulbul-like chattering calls. The Dapple-throat resembles immature robin-chats or thrushes, but lacks spotting and scaling on the upperparts.
Amazonian Streaked-Antwren
Myrmotherula multostriata
Small streaked antwren of riparian habitats. Males are white with black streaking; females are similar but with an extensive reddish wash. Tail very short in both sexes. Usually found in waterside vegetation around still or slow-moving water bodies like streams and lakes, where it forages low in vegetation overhanging the water. Gives two main songs: an even-pitched, accelerating trill of musical notes, and a slow ascending-descending series of whistled notes. The latter is one of the most characteristic bird sounds around oxbow lakes in Amazonia.
