White-winged Tanager
Piranga leucoptera
Fairly small tanager of humid evergreen and pine-oak forest in foothills and highlands. Found mainly in the canopy, usually in pairs or small groups that sometimes join mixed-species feeding flocks. Distinctive male is brilliant red with black mask and black wings with neat white wingbars. Female has same plumage pattern as male but is greenish and yellow overall. Calls are high lisping whistles.
识别特征
The white-winged tanager is approximately 13 cm (5.1 in) long and weighs 13 to 20 g (0.46 to 0.71 oz). The nominate male is mostly red, with a black "mask" and black wings with white wing bars. The female is dull olive-yellow, but retains the black wings and white wing bars. The juvenile is similar to the female, but duller. The male P. l. latifasciata is darker red and the female a more intense yellow; both sexes have broader white wing bars. The male P. l. venezuelae differs from the nominate only in having a smaller "mask". P. l. ardens is similar to venezuelae but the lower wing bar is narrower.
分类信息
The white-winged tanager and the other species of genus Piranga were originally placed in the family Thraupidae, the "true" tanagers. Since approximately 2008 they have been placed in their current family. It and the red-headed tanager (Piranga erythrocephala) have sometimes been placed in genus Spermagra.<p>The white-winged tanager has four recognized subspecies, the nominate Piranga leucoptera leucoptera, P. l. latifasciata, P. l. venezuelae, and P. l. ardens.

分布与栖息地
The range of white-winged tanager consists of several discontinuous areas. The four subspecies are found thus:<p>In Mexico and northern Central America the white-winged tanager inhabits pine-oak forest and shady coffee plantations. In the rest of its range it is found in humid montane forest, cloud forest, and mature secondary forest. It also can be found in coffee plantations and drier forest. In Mexico it ranges between 100 and 1,800 m (330 and 5,910 ft) of elevation, though it is mostly found above 600 m (2,000 ft) on the Atlantic side. In Costa Rica it is found between 1,100 and 1,850 m (3,610 and 6,070 ft). In Venezuela north of the Orinoco River it ranges from 650 to 2,100 m (2,130 to 6,890 ft) and south of the river from 1,000 to 1,800 m (3,300 to 5,900 ft). It is found between 600 and 2,000 m (2,000 and 6,600 ft) in Colombia, Ecuador, and Peru.

行为
The white-winged tanager's diet includes fruit, berries, seeds, and probably insects. Pairs and small groups forage in the forest canopy or edge and may join mixed-species foraging flocks.<p>A female white-winged tanager was documented building a small cup nest high up on a mossy branch. No other information about the species' breeding phenology has been published.<p>The white-winged tanager's song is "a thin, wiry 'e-seé-se-whéét'" [1]. It has a variety of calls [2] [3] [4].

Taiwan Cupwing
Pnoepyga formosana
Minuscule endemic songbird. Short wings, very short tail, and rather long legs give it the appearance of a brown ping-pong ball set on tiny chopsticks. Dark brown above, black-and-white scaly pattern below. Constantly shakes its wings as if cold. Moves about on the ground and in low vegetation in montane forests, where very difficult to see. Song a loud, strident, high-pitched series of three whistled phrases, with a pause after the first.
Slaty Egret
Egretta vinaceigula
A small, dark egret with a rusty-buff throat and yellow-green legs and feet. It occurs solitarily or in small groups, preferring marshes and floodplains; it avoids open areas, seeking cover in small channels or near long grass. Slaty Egrets walk slowly, shuffling their feet to surprise fish and frogs. Although it is mostly resident, it can disperse widely outside of its core range. The similar Black Egret differs by having a dark throat, dark legs with yellow feet, and occasionally foraging in a distinctive “umbrella” position, whereby it covers its head with its wings.
Manx Shearwater
Puffinus puffinus
Small black-and-white shearwater that flies with snappy wingbeats. Pay attention to its face pattern: typically quite dark and smudgy, with white curling up behind the cheek. Underwing is mostly white, sometimes with dark markings. Flies low to the water with quick wingbeats, almost recalling an alcid; occasionally arcs up high in strong wind. Prefers cooler ocean waters in the North and South Atlantic; rarely seen from land. Rare but seemingly increasing in the Pacific. Found singly or in small flocks, sometimes with other shearwaters. In Caribbean and western Atlantic, most similar to Sargasso Shearwater but shorter-tailed and darker-faced, with white under the tail.
