Orange-winged Pytilia
Pytilia afra
Unusual and pretty member of the waxbill family. Shows fine olive-green barring below, yellow edges to the wing feathers, and red on the tail. Generally scarce and inconspicuous. Found in the understory of moist habitats, including miombo and other lush woodland, and in forest edge. Usually seen singly or in pairs. Calls include inconspicuous “tew”, “tip”, and rasping notes. Similar to Green-winged Pytilia but found in moister habitats and separated by finer barring below, yellow wing edges, and different pattern of red on the face of the males.
识别特征
The orange-winged pytilia is 11 cm (4.3 in) long and weighs 14–15 g (0.49–0.53 oz). The male's forehead, face and chin are red, and its crown and nape are grey. Its back is green, with an olive tinge. Its greater coverts are orange, and its primary coverts and flight feathers are blackish-brown, with orange edges. Its rump is crimson. The outer webs of its tail are red, and the inner webs are brown. Its throat and upper breast are pale grey, and its breast is olive. There are off-white bars on its breast and belly. Its legs are pale pink or pinkish-brown. Its eyes are orange or red, and its beak is red. The female has a greyish head, with no red. Its back and wings are duller than the male, and the bars on its underparts are broader. The immature bird is like the female, but is drabber.
分类信息
The orange-winged pytilia 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 finches in the genus Fringilla and coined the binomial name Fringilla afra. Gmelin gave the locality as Angola. The specific epithet is from Latin afer meaning "Africa". Gmelin based his account on the "red-faced finch" that had been described and illustrated in 1776 by the English naturalist Peter Brown. The orange-winged pytilia is now one of five pytilias placed in the genus Pytilia that was introduced in 1837 by the English naturalist William John Swainson. The species is monotypic: no subspecies are recognised.

It has an estimated global extent of occurrence of 8,160,000 km2 (3,150,000 sq mi). Its habitat is edges of forests, miombo woodland and wooded grasslands, usually in moist areas. It is found at elevations up to 1,800 m (5,900 ft) above sea level.

行为
The orange-winged pytilia is found in small flocks, and can form larger, looser flocks when it is not breeding. It feeds on the ground, eating seeds and probably also insects. In the non-breeding season, it can move great distances to find food. Its call is seee, and its song is quickly repeated whistles. The orange-winged pytilia is parasitised by the broad-tailed paradise whydah, which mimics its call. The orange-winged pytilia's breeding season is April to May in the southeastern Congo Basin, January to May in Zambia and Zimbabwe, March to June in Malawi, and April to June in Tanzania. The eggs weigh approximately 1.42 g (0.050 oz), and those of the brood parasite weigh about 15% more, at 1.64 g (0.058 oz). The pytilia's incubation period is 12 to 13 days, and the nestling period is 21 days.

Caspian Tern
Hydroprogne caspia
Largest tern in the world; widespread but typically uncommon. Thick, bright-red bill is distinctive; most have small dark marking near the tip. Note solid black cap in summer which turns to black streaks in winter. Juveniles have V-shaped markings on the upperparts. Feeds by cruising over lakes, rivers, estuaries, and reservoirs looking for fish, then plunging to catch them. Smooth wingbeats, more gull-like than choppy flight of small-bodied terns. Very vocal, giving loud raucous screams. Compare especially with Royal Tern, which is slightly smaller and more slender, and has a thinner, more orangey bill.
Pygmy Nuthatch
Sitta pygmaea
Small nuthatch of coniferous forests in western North America. Note dark grayish-brown cap and buffy underparts with grayish sides. Very similar plumage to Brown-headed Nuthatch, but no range overlap. Usually occurs in small flocks high in the crowns of pine trees, often mixed with other songbirds. Listen for cute pips and squeaks.
Giant Hummingbird
Patagona gigas
Largest hummingbird in the world, with its size compensating for rather drab plumage; no similar species. Plumage is drab greenish above with a big whitish rump patch and dingy below with variable rusty tones and dusky spotting. Favors rather open and dry habitats from matorral and gardens to Andean scrub; often perches conspicuously atop bushes or on roadside wires. Flight is “slow” with powerful wingbeats, often hovering in jerky manner and chasing insects. Loud sharp calls can draw attention.
