Rufous-bellied Seedsnipe
Attagis gayi
Chunky, generally uncommon, rather grouselike bird of the high Andes. Found in pairs or small groups on bogs, stony slopes, and in bleak moorland of puna and páramo zones. Lacey “chainmail” pattern to upperparts is beautifully cryptic, and birds sometimes freeze when alarmed making them more difficult to see. No similar species in range; note the short stout bill and rusty underparts. Flight strong and fast, and flushes with loud shrieking choruses.
识别特征
The rufous-bellied seedsnipe is 27 to 30 cm (11 to 12 in) long and weighs about 280 to 400 g (9.9 to 14 oz). The sexes are alike. The nominate subspecies' upperparts have an intricate scallop pattern of rufous-brown and blackish; its underparts are unmarked pale pinkish cinnamon. Subspecies A. g. latrelillii has a deeper rufous cinnamon than the nominate in its vent area and a scalloped breast. A. g. simonsi's breast is a darker pinkish cinnamon than the nominate's; it is paler above with finer markings. Juveniles much resemble adults but with somewhat finer markings on their upperparts.
分类信息
The rufous-bellied seedsnipe shares its genus with the white-bellied seedsnipe (A. malouinus). They and the other two seedsnipes are closely related to the sandpipers of family Scolopacidae. It has three subspecies, the nominate A. g. gayi, A. g. latrelillii, and A. g. simonsi. At least one publication has suggested that A. g. latrelillii might deserve to be recognized as a species.<p>The rufous-bellied seedsnipe's specific epithet commemorates the French naturalist Claude Gay.[citation needed]

分布与栖息地
Subspecies A. g. latrelillii of rufous-bellied seedsnipe is found far from the other subspecies, on seven high volcanoes in north-central Ecuador. A. g. simonsi is found from central Peru south through northern Chile and western Bolivia into northwestern Argentina. The nominate A. g. gayi is found from north central Chile and west central Argentina south almost to Tierra del Fuego.<p>The rufous-bellied seedsnipe inhabits alpine terrain in the Andes, often as high as the snow line. It frequents boggy and other moist areas but also occurs in drier and rockier landscapes. Subspecies A. g. latrelillii is typically found in páramo. In the northern half of its range it mostly is found between 4,000 and 5,500 m (13,100 and 18,000 ft). Further south it occurs down to 2,000 m (6,600 ft) and in the extreme south as low as 1,000 m (3,300 ft).

行为
The rufous-bellied seedsnipe is essentially non-migratory, though southern populations are thought to move to lower elevation in the austral winter. It is a strong flier and when flushed flies in a fast zigzag.<p>The rufous-bellied seedsnipe feeds on plant matter, typically in moist areas, but details of its diet are lacking.<p>Little is known about the rufous-bellied seedsnipe's breeding biology. It lays eggs during September and October in Chile; further north the season extends to December. Its nest is a shallow scrape in the ground and the clutch size is typically four eggs.<p>The rufous-bellied seedsnipe frequently calls when flying and also while running; its call is "a melodic-sounding 'gly-gly-gly...' or 'cul-cul-cul...'" which several birds may make simultaneously.

Crocker Jungle Flycatcher
Cyornis ruficrissa
Drab, medium-sized flycatcher with a long slender bill. Endemic to the montane and submontane forests of Borneo. Look for a warm rufous tail, white throat, and pale underparts. Forays from a low perch in the understory or forest edge; otherwise generally unobtrusive and difficult to spot in dark understory. Vocalizations include a disjointed series with buzzy and scratchy notes. Formerly grouped with Sulu Jungle Flycatcher and Philippine Jungle Flycatcher under “Chestnut-tailed Jungle Flycatcher.”
Collared Palm-Thrush
Cichladusa arquata
Odd and distinctive thrush. Note the gray head, pale eye, rufous back, and black mark outlining the throat. Found locally in thickets within palm savanna. Distinctive song consists of an emphatic series of airy, wailing notes. Also gives chattering and rasping calls. Spotted Morning-Thrush is similar, but Collared is separated by its pale eye, bright rufous back, and lack of spotting below. Somewhat similar to nightingales and scrub-robins, but easily separated by its black throat markings.
Rufous-headed Ground-Roller
Atelornis crossleyi
Chunky, long-legged, richly colored bird. White shoulder marks are conspicuous in flight. Elusive and shy; unlikely to be seen by those not searching for it. Found in eastern rainforest, at upper and middle elevations. Feeds in the understory, usually in thick areas, often with bamboo. Avoids disturbance by fleeing on the ground or making short flights. Song is a quick hollow “kwowp” note that is repeated slowly, delivered from a low perch, often a mossy log. Lacks the intricate scaly marks of Scaly Ground-Roller and the pale underparts and complex head pattern of Pitta-like Ground-Roller.
