Gray-breasted Seedsnipe
Thinocorus orbignyianus
Stocky, rather small, quail-like bird of the Andes. Favors open rocky slopes, stony plains, and adjacent bogs. Found in pairs or small groups. Male has hooting song given from low mounds or fence posts and during display flight. Flight is strong and fast; flushes with loud bleating chatters. Similar Least Seedsnipe is smaller, favors sandier and grassier habitats, and often occurs in lowlands. Note plain gray breast of male Gray-breasted unlike the black Y pattern present on Least Seedsnipe.
识别特征
The grey-breasted seedsnipe is 19 to 24 cm (7.5 to 9.4 in) long and weighs 96 to 140 g (3.4 to 4.9 oz). The male has a gray head, neck, and upper breast, and a white throat with a black border. Its upperparts are cinnamon buff in a vermiculate pattern. The wings show white bars above and below in flight. The lower breast and belly are white; a narrow black band separates them from the upper breast. The female's head and breast are pale buff with heavy dark streaks. The two subspecies are essentially alike though T. o. ingae has shorter wings and legs than the nominate.

分布与栖息地
The grey-breasted seedsnipe is a bird of the Andes. T. o. ingae is found from the Department of Cajamarca in Peru through western Bolivia into northern Chile and northwestern Argentina as far as Catamarca and possibly Mendoza Provinces. The nominate subspecies is found from northern Chile's Antofagasta Region and northwestern Argentina's La Rioja Province south into Tierra del Fuego. It is a year round resident in most of its range though it moves north out of Tierra del Fuego in winter. It also makes seasonal altitudinal movements.<p>The grey-breasted seedsnipe inhabits Puna grassland, mostly in areas with low matted vegetation or short grass near bogs. In Peru it is common between 3,400 and 5,000 m (11,200 and 16,400 ft) elevation. Further south it mostly breeds above 1,000 m (3,300 ft) but can be found in summer below 400 m (1,300 ft) in Chilean Patagonia.

Black-headed Parrot
Pionites melanocephalus
Medium-sized, stocky parrot that is distinctive even under poor lighting conditions; note black cap and contrasting white-and-yellow pattern on face, breast, and belly. Common in a variety of forest types, especially those on sandy soils. Usually seen in groups of 4-5 or more. Groups forage quietly on fruit and flowers in forest canopy, flushing noisily with distinctive whirring wingbeats that are audible at some distance. Flight call is a penetrating screech, somewhat similar to Red-fan Parrot but higher-pitched and less variable.
Spotted Owlet
Athene brama
A small uncrested owl with a round head and a short tail. It is grayish-brown overall with white spots above while its underparts are white with brown bars. Note the distinctive white eyebrows and neck-band. Often active at dawn and dusk when it utters a loud “chirurr-chirurr-chirurr” laugh in addition to a variety of high-pitched squeals and whistles. Inhabits all kinds of open habitats but avoids dense forest and wetter regions.
Rufous Twistwing
Cnipodectes superrufus
Large flycatcher with uniform bright cinnamon plumage. Inhabits the understory of large stands of bamboo within humid forests. The song is a series of descending musical whistles “pew-pur-pur-pur-pur.” The smaller Brownish Twistwing has a whitish belly. Rufous Casiornis is much smaller, with different proportions, and does not usually occur in humid forests.
