Yellow-browed Warbler
Phylloscopus inornatus
Small, active warbler with greenish upperparts, white underparts, distinct pale yellowish eyebrow, and distinct pale wingbars (upper wingbar short and less distinct). Overlaps in range with many other warbler species; compare especially with Hume’s Warbler, Pallas’s Leaf Warbler, and Two-barred Warbler. Breeds in mid- to high-elevation forests and winters in a wide range of wooded and scrubby habitats, where usually rather active; sometimes hovers to pick bugs from leaf tips. Call a distinctive, 2-syllable, upslurred "tsu-weet." Song is a very high, thin series of alternating long and short notes: “tseee-ts’a’wi-tseeeee.”
识别特征
This is one of the smaller Old World warblers, at 9.5–11 cm long and weighing 4–9 g distinctly smaller than a chiffchaff but slightly larger than Pallas's leaf warbler. Like many other leaf warblers, it has overall greenish upperparts and white underparts. It also has prominent double wing bars formed by yellowish-white tips to the wing covert feathers (a long bar on the greater coverts and a short bar on the median coverts), yellow-margined tertial feathers, and long yellow supercilium. Some individuals also have a faint paler green central crown stripe though many do not show this.<p>It is not shy, but its arboreal life style makes it difficult to observe. It is almost constantly in motion. Its song is a high-pitched medley of whistles; the call is piercing, often disyllabic "tseeweest", strikingly loud for the bird's small size. The only real possibility of confusion is with the similar-looking Hume's leaf warbler (P. humei), which in the limited area of overlap has duller colours, a faint second wing bar and dark legs and lower mandible. Their songs and calls are clearly distinct, with Hume's having a more chirping "chwee" call. It can easily be distinguished from Pallas's warbler as it does not have the conspicuous yellow central crown stripe and rump patch shown by that species.
分类信息
The yellow-browed warbler was first described by the English zoologist Edward Blyth in 1842 and given the binomial name Regulus inornatus. The current genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). The specific inornatus is Latin for "plain".

American White Pelican
Pelecanus erythrorhynchos
Extremely large and conspicuous. White with black wingtips. Very long, orange bill with pouch for scooping up fish. Forages in flocks, swimming together to concentrate fish. Often soars in flocks, infrequently flapping, during migration and when traveling between feeding sites.
Chestnut-breasted Whiteface
Aphelocephala pectoralis
Small bird with stubby bill, found in open shrubland in stony country of arid northeastern South Australia. Warm brown above, white below, with broad rusty-brown chest band, reddish-brown marks on the flanks, pale eye, grayish throat, and white mark above bill. Forages on the ground in small flocks. Call is a steady warbling twitter.
Cuban Emerald
Riccordia ricordii
A pugnacious hummingbird that feeds on flowers and insects and is sometimes found flycatching. Inhabits a broad range of habitats. Often tame around humans. The long-tailed male is swathed entirely in iridescent green and has a distinctive red base to the bill, except for a white patch below the belly and a white spot behind the eye. The female is metallic green above, dingy white below, and has a relatively long, forked tail. The female Bee Hummingbird is much smaller, shorter billed, shorter tailed, and is iridescent turquoise above unlike the Cuban Emerald. Female Ruby-throated Hummingbirds have shorter, unforked tails with white on the tail tip. Vocalizations include a prolonged jumbled series of high-pitched squeaks and buzzes and a high-pitched but descending “tsee, tsee, tsee, tse, tse.”
