Pink-backed Pelican
Pelecanus rufescens
Small by pelican standards, though still a very large bird! Adult is mostly pale gray with a pinkish bill and (in breeding plumage) a gray crest. Immature darker gray. Found in many wetland habitats with open water, including lakes, ponds, and coastal lagoons. Usually in small groups. Often confused with Great White Pelican, but Pink-backed is much smaller. In flight, the outer wing is dark gray rather than black, and it contrasts much less with the pale portions of the wing.
识别特征
It is a relatively small pelican, although by no means is it a small bird. Its length is from 125 to 155 cm (49 to 61 in), wingspan is 2.15–2.9 m (7.1–9.5 ft) and body mass is from 4 to 7 kg (8.8 to 15.4 lb). The bill is 30 to 38 cm (12 to 15 in) in length. The plumage is grey and white, with a pinkish hue on the back occasionally apparent (never in the deep pink of a flamingo). The top of the bill is yellow and the pouch is usually greyish. Breeding adults have long feather plumes on the head.<p>It shares its habitat with the great white pelican, which is generally larger and has white instead of greyish plumage.
分类信息
The pink-backed pelican was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the other pelicans in the genus Pelecanus and coined the binomial name Pelecanus rufescens. Gmelin based his description on the "red-backed pelican" that had been described in 1785 by the English ornithologist John Latham in his multi-volume work A General Synopsis of Birds . Latham had been sent a specimen from West Africa. The specific epithet rufescens is Latin for "reddish". The species is monotypic: no subspecies are recognised.

Nutting's Flycatcher
Myiarchus nuttingi
Medium-sized Myiarchus flycatcher very similar to Ash-throated Flycatcher of western North America but slightly brighter overall, with bushier crest and browner face. Best identified by voice. Ash-throated is a winter migrant throughout much of Nutting’s range. One form of Nutting’s occurs in arid scrub and oak woods of lowlands and foothills; its commonest calls are a loud “wheek” and bickering “kwidik-kwidik.” A second form of Nutting’s (“Ridgway’s Flycatcher”) occurs in hedges and semiopen country in lowlands from Chiapas south to Central America; its commonest calls are “wh’beer” and “dee-dee-dee-dee.”

Rufous-browed Flycatcher
Anthipes solitaris
Unique-looking flycatcher with a gleamingly clean white throat and a strong rusty orange tinge to the brow and forehead. Overlaps with closely related White-gorgeted Flycatcher but lacks that species’s gray face and black border to the white throat patch. Inhabits foothill and montane forests, where it forages close to the ground in lower vegetation. Both flycatches and gleans for prey more actively. Song is a high, thin series of whistles; a simple version is “tee-tee-tew’, to which additional phrases may be added. Vocal for a flycatcher, and calls often, giving harsh rattles, chips and chiks, and high thin notes.

Rufous-chested Flycatcher
Ficedula dumetoria
This handsome little flycatcher has the endearing habit of fanning its tail and flicking its wings when agitated. The male’s long slender white eyebrows and orange breast make him unmistakable; wintering male Mugimaki Flycatchers may cause some confusion, but that species has a smaller, block-like eyebrow patch and a broader, shorter white wing patch. Females are brown above and whitish below with an orange chest and rufous tail; her combination of plain brown wings, warm-toned tail, and a fairly uniform head pattern separate her from female Snowy-browed and Mugimaki Flycatchers. Female “blue flycatchers” can be similar, but they are more slender and have proportionally longer bills. Found in foothill and montane forests, where it forages in dense low thickets, typically singly or in pairs. Song is a brief 3–4-note phrase of very high, thin notes: “tsee-a-tsee-tsee”, or “tsee-ah-tsee”.
