Green-bellied Hummingbird
Saucerottia viridigaster
Plain and often confusing hummingbird found along lower to middle slopes of the Andes. Note its limited range in the eastern Andes of Colombia and the Andes of Venezuela. Plumage is mostly green with rusty-brown rump and tail. Its name is deceptive as the belly is typically brown or buff, not green. Similar to Rufous-tailed Hummingbird, but bill is darker and less red, and rump and tail are browner and less rufous. Inhabits forest edge, clearings, and plantations. Birds found in the Tepui region are now considered a separate species, Copper-tailed Hummingbird.
识别特征
The green-bellied hummingbird is 8 to 10.5 cm (3.1 to 4.1 in) long and weighs 4.5 to 6.7 g (0.16 to 0.24 oz). Both sexes of both subspecies have a straight, medium length, blackish bill with a pink to reddish base to the mandible. Adult males of the nominate subspecies have a dull golden-green head and back and olive green to brownish rump and uppertail coverts; the last sometimes have a purplish tinge. Their wings are dark purple brown and their tail deep blue to violet blue. Their underparts are a dark shining green becoming grayish brown at the vent. Their undertail coverts are grayish buff with paler edges. Adult females are similar to males with the addition of white fringes on the throat feathers and bronze or brownish edges to the tail feathers. Juveniles resemble females but have grayish brown or brownish gray underparts. Subspecies S. v. iodura has a coppery to purple tail and is otherwise like the nominate.
分类信息
The green-bellied hummingbird was formerly placed in the genus Amazilia. A molecular phylogenetic study published in 2014 found that the genus Amazilia was polyphyletic. In the revised classification to create monophyletic genera, the green-bellied hummingbird was moved by most taxonomic systems to the resurrected genus Saucerottia.<p>The green-bellied hummingbird previously was assigned six subspecies. By early 2023 most taxonomic systems had created the copper-tailed hummingbird (S. cupreicauda) containing four of them. They retain the other two subspecies in the green-bellied, the nominate S. v. viridigaster (Bourcier, 1843) and S. v. iodura (Reichenbach, 1854). However, the South American Classification Committee of the American Ornithological Society does not recognize the copper-tailed hummingbird as a separate species.

分布与栖息地
Subspecies S. v. viridigaster of the green-bellied hummingbird is found in north-central Colombia on the east slope of the Eastern Andes. S. v. iodura is found in the Andes of western Venezuela. The species inhabits a variety of semi-open to open subtropical landscapes including the edges of gallery forest, plantations, scrub- and brushlands, river islands, and low secondary forest. It mostly occurs on the lower to middle slopes of the Andes at elevations between 400 and 1,700 m (1,300 and 5,600 ft).

Slaty-chinned Longbill
Toxorhamphus poliopterus
A small, sunbirdlike bird of montane forest. Long, thin, curved bill and olive body with slaty wings, head and contrasting yellow, lower throat. Similar to several other species, but Slaty-chinned Longbill lacks the gray chest of Spectacled Longbill and female Black Sunbird, lacks the yellow eye-brow of female Olive-backed Sunbird and has a contrasting gray head and yellow throat, unlike the lower elevation Yellow-bellied Longbill. Song, a high-pitch jumble of slurred notes sometimes interspersed with loud downward “chew!” calls.
Dark-breasted Rosefinch
Procarduelis nipalensis
Dark medium-sized rosefinch. Male is is dark pink with a lighter throat and eyebrow. Female is dark brown with light wingbars. Both sexes can be similar to Vinaceous Rosefinch, but note male’s different head pattern and female’s unstreaked underparts and noticeable wingbars. Forages on the ground in montane and hill forest, forest edge, and rocky meadows and slopes. Gives a wheezy sparrow-like “wheer.”
Philippine Cockatoo
Cacatua haematuropygia
A rare large parrot of forest on Palawan and several other scattered islands. Heavily persecuted. Can roost on small islets or in mangroves and forage in more open areas, including agricultural fields. Mostly white with a pale yellowish cheek, undertail, and underwings and a red patch under the base of the tail. Note the pale bill and the bare white skin around the eye. Hidden crest is usually held flat. Unmistakable if seen well, but a distant bird in flight could be confused with an egret. Voice includes various nasal or rasping squawks.
