White-winged Cinclodes
Cinclodes atacamensis
Uncommon to fairly common in the high Andes, where usually outnumbered by similar but smaller Cream-winged Cinclodes. Favors streams and bogs with running water and also lakeshores. Generally less confiding than Cream-winged Cinclodes. Told from Cream-winged by brighter, rustier back and more contrasting white markings with broader wing stripe and big white tail corners as opposed to smaller buff tail corners on Cream-winged. Voice also quite different.
Identification
The white-winged cinclodes is 19 to 20 cm (7.5 to 7.9 in) long and weighs 45 to 56 g (1.6 to 2.0 oz). It is a fairly large cinclodes with a decurved bill. The sexes have the same plumage. Adults of the nominate subspecies have a whitish supercilium, brownish gray lores, grayish brown ear coverts with reddish tones, and a whitish malar area with some faint darker flecks. Their crown is grayish brown and their upperparts rich reddish brown. Their wing coverts are reddish brown. Their wings have white at the bend and blackish flight feathers with white across their base forming a conspicuous band. Their tail's central feathers are dark fuscous brown with paler shafts and the rest are blackish brown with increasingly large white spots from the inner to the outer feathers. Their throat is whitish with faint darked specks, their breast and sides buffy grayish, their belly brownish gray, their flanks rich brown, and their undertail coverts mottled brown and grayish white. Their upper breast has faint pale streaks and flecks that almost disappear on the lower breast. Their iris is dark brown, their bill blackish to dark horn, and their legs and feet dusky brown. Juveniles are like adults with pale edges on the feathers of their lower back and less distinct breast markings. Subspecies C. a. schocolatinus has darker brown upperparts and grayer underparts than the nominate, with dark brown sides and flanks.
Taxonomy
The white-winged cinclodes has two subspecies, the nominate C. a. atacamensis (Philippi, 1857) and C. a. schocolatinus (Reichenow, 1920). Some authors have suggested that it and the white-bellied cinclodes (C. palliatus) are sister species, but genetic tests were inconclusive.

Range and habitat
The nominate subspecies of the white-winged cinclodes is found from central Peru's Department of Ancash south through western Bolivia to Chile's Santiago Metropolitan Region and northwest Argentina's Mendoza Province. Subspecies C. a. schocolatinus is found in west-central Argentina's Córdoba and San Luis provinces. The species inhabits puna grasslands and slopes with rocks or shrubs. It almost always is along flowing streams and rivers. In elevation it mostly ranges between 2,800 and 4,500 m (9,200 and 14,800 ft) but locally occurs as low as 2,200 m (7,200 ft).

Behavior
The white-winged cinclodes is mostly a year-round resident, though some members of subspecies C. a. schocolatinus and the southernmost population of the nominate move to lower elevations after breeding.<p>The white-winged cinclodes' diet has not been fully documented but is known to include larval and adult insects, spiders, and snails. It usually forages singly or in pairs, gleaning its prey from the ground and mud along the edges of watercourses.<p>The white-winged cinclodes is thought to breed during the austral spring and summer; its season includes at least October to December. It is thought to be monogamous. It nests in a chamber at the end of tunnel it excavates in an earthen bank, in a rock crevice, or in the wall of a human structure. It pads the chamber bottom with dry grass and hair. The clutch size is two eggs. The incubation period, time to fledging, and details of parental care are not known.<p>The white-winged cinclodes' song is a trill and its call "a loud, whistled 'wheet' ".

Snowcap
Microchera albocoronata
Tiny hummingbird; male is unique and beautiful: his body is the color of red wine, and he has a bright white cap. Unmistakable in limited range. Female is less striking, but note small size, snowy white underparts, and short straight bill. Most often seen feeding at small purple flowers in gardens and forest edges
Eastern Meadowlark
Sturnella magna
Streaked brown above and yellow below with distinctive black "V" on breast. In flight, short wings and spiky tail with white outer feathers are apparent. Breeds in fields and grasslands throughout eastern North America. Also occurs throughout eastern and southern Mexico and Central America, into northern South America, and in Cuba. Winters in dense grassy habitats, often in small loose groups. Extremely similar to Western Meadowlark and best distinguished by voice: listen for high-pitched, clear whistles and short buzzy calls. In winter, plumage looks slightly darker and more contrasty than Western Meadowlark, with a more contrasting head pattern. Eastern is somewhat more tied to more pristine grassland habitats, but with some overlap.
Long-tailed Potoo
Nyctibius aethereus
Large potoo with a long graduated tail. Mostly rusty brown with streaked underparts, a conspicuous pale shoulder patch, and a whitish moustache. Occurs from the lower to the upper levels of humid forests. The song is an undulating “waa-OO-uh,” usually sung on moonlit nights.
