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.

It feeds on the buds and leaves of herbs and succulent plants.<p>The grey-breasted seedsnipe breeds between October and February. It places its nest in a clump of grass or other vegetation, usually near water. The clutch size is four eggs.<p>The grey-breasted seedsnipe's song is "a repetitive, dove-like “coocoop...coocoop...coocoop...". It is given from the ground and also during dusk and dawn display flights. It also makes a "snipe-like 'chrp'" when flushed.

Serra Antwren
Formicivora serrana
Small, strikingly-plumaged antbird with a long tail and a very restricted range. Inhabits the understory of low stature or regenerating forests, forest edges, scrub, and abandoned plantations where it is very active and occasionally joins mixed-species flocks. Much plumage variation, with coastal males near Rio de Janeiro (formerly split as Restinga Antwren) being almost uniformly sooty-black with only slightly grayer back and spotted white wingbars. Two more northerly subspecies vary between rufous-brown and dark gray above, but both are black below with a bold white eyebrow and white wing spots. In all subspecies, females are pale whitish below and brown above with a bold white eyebrow. Male song is a monotonous series of harsh chip notes; female gives nasal squeaks.
Scarlet-rumped Trogon
Harpactes duvaucelii
Striking trogon with an extensive blue gape and a similarly-colored patch above the eye. Male has a brilliantly scarlet rump and underparts. Female has an orangish rump, a yellow breast, and a pinkish-red belly. Both sexes have a dark head (paler in females) and densely barred wings. Inhabits broadleaved evergreen forests from lowlands up into the foothills. Forages from a perch, but typically sits quite still and acts sluggish. Gives a rapidly accelerating series of squeaks.
Pied Honeyeater
Certhionyx variegatus
Medium-sized honeyeater with long decurved bill, nomadic across arid and semi-arid inland Australia. Male black with white belly, wing patches, and tail panels; distinctive patch of blue skin beneath eye. Female and juvenile plain brown, with subtly patterned wings and faint speckles on chest. This species wanders in search of flowering shrubs and can be absent one year, common in large flocks the next. Much larger than Black Honeyeater (which has completely black upperparts). Calls include a slowly whistled phrase of several notes.
