Rufous Sabrewing
Pampa rufa
Very large and spectacular hummingbird of humid forest and brushy woodland in highlands of Chiapas and northern Central America; uncommon and local. Feeds mainly at low to middle levels, often inside shady understory. Male and female look similar, with thick, slightly arched black bill, pale rusty underparts, and large, broad tail with rusty base and buffy corners. No similar species in its localized range.
识别特征
The rufous sabrewing is 12.1 to 14 cm (4.8 to 5.5 in) long and weighs an average of 7.5 g (0.26 oz). Its black bill is straight, stout, and broad. The sexes have essentially the same plumage. Their upperparts are bright metallic bronze green to greenish bronze; the crown is slightly darker and duller and the uppertail coverts are more bronzy. Their face is cinnamon with a white spot behind the eye and their underparts are cinnamon that is slightly paler down the center. Their central pair of tail feathers is metallic bronze to greenish bronze. The next pair is similar with a wide diffuse blackish band near the end and cinnamon tips. The next two pairs have cinnamon bases with a sharper blackish band and cinnamon tips. The outermost pair's outer web is cinnamon.
分类信息
The rufous sabrewing was originally described as Pampa rufus, later moved to genus Campylopterus, and later still restored to Pampa with the specific epithet revised to match its gender to the genus. The North American Classification Committee of the American Ornithological Society, the International Ornithological Committee (IOC), and the Clements taxonomy have adopted the binomial P. rufa. However, BirdLife International's Handbook of the Birds of the World (HBW) retained it as Campylopterus rufus.<p>The taxonomic systems agree that the rufous sabrewing is monotypic.

分布与栖息地
The rufous sabrewing is found on the western slope of highlands from Sierra Madre de Chiapas in the Mexican state of Oaxaca southeast through Guatemala into El Salvador as far as Volcán de San Salvador in El Boquerón National Park. It inhabits the interior and edges of humid evergreen montane forest, pine-oak forest, and coffee and other plantations. In elevation it ranges between 900 and 2,000 m (3,000 and 6,600 ft) but is most abundant above 1,300 m (4,300 ft).

行为
The rufous sabrewing is thought to be mostly sedentary, though it may make elevational changes or move about seeking nectar sources.<p>The rufous sabrewing forages for nectar at a variety of flowering plants, shrubs, and trees, though its diet has not been greatly studied. In mostly stays low, often in the understory, but will forage as high as the canopy at the forest edge. Males defend nectar-rich feeding territories. In addition to nectar, the species feeds on small insects captured by hawking from a perch.<p>Males sing to court females at leks in dense understory. Females make a small cup nest of moss lined with thistle down and covered with lichen; some of the moss hangs down as a "beard". It is placed on a thin branch, usually an exposed one within about 2 m (7 ft) of the ground. The female incubates the clutch of two eggs for 15 to 16 days and fledging occurs 23 to 26 days after hatch.<p>The rufous sabrewing's song is "varied, strong, squeaky chipping and chattering, also short, rich, warbled phrases." It also makes "a shart, nasal squihk, a slightly more metallic pli'ik, and a hard, chipping chi'ilrr chik-chik-chik-chik" calls.

Nelicourvi Weaver
Ploceus nelicourvi
Dark olive-green forest-dwelling weaver. Male has a black cap and yellow collar; female plainer. Both sexes have a chestnut undertail. Madagascar endemic that is found in eastern and northern rainforest, and sometimes in scrub and gardens. Usually seen solo or in pairs, sometimes joining mixed feeding flocks. Elaborate woven nest has a long entrance tunnel, and hangs conspicuously in an open area. Song is a high-pitched sizzling; call is a husky, repeated “chey.”
Chestnut-bellied Partridge
Arborophila javanica
Brilliantly colored small partridge of montane and foothill forests. Often difficult to see in the gloom and tangle of shaded vegetation, but note slate-gray back and chest, rusty belly, and bright orange-and-black face pattern. Like other Arborophila partridges, typically forages on the forest floor in small groups. Song is a fast and gradually rising series of “whew” notes; when duetting, one bird gives the aforementioned song while its partner gives a slower, lower-pitched “boo-goo, boo-goo, boo-goo.”
Common Greenshank
Tringa nebularia
Gentle-eyed large wader with a slightly upturned bill. Note overall grayish plumage with white belly and greenish legs. In flight, appears dark above with a broad white stripe up the middle of the back. Slightly larger and lankier than Common Redshank. Usually seen as singles or small groups. Listen for mellow “tewtewtew.” Feeds mainly by striding in water, picking and sweeping with its bill. Breeds across northern Europe and Asia; migrants and wintering birds in Africa, southern Asia and Australia occur in varied wetland habitats.
