Tibetan Snowcock
Tetraogallus tibetanus
Although its loud, hoarse calls can often be heard echoing in the high mountain slopes it calls home, this large game bird can often prove difficult to see. Extremely well-camouflaged on rocky slopes and in boulder fields. Gray head is marked with a comma-shaped white brow and a bright orange patch of skin behind the eye. Back is brown with thick black-and-white striping and the underparts are snowy-white with thin black stripes.
Identification
Smaller than Himalayan snowcock, this species has a grey head and neck with a white patch behind the eye and above the dark cheek. Chin, throat and breast are white, with two grey bands on the breast. Grey wing coverts and tertials have a white trim. The secondaries have a broad white trailing edge that forms a wing band. Underparts are white with black streaks on flanks and belly. The tail is rufous brown and the undertail coverts are black. Legs and beaks are reddish. Sexes are similar, but female has buff in postocular patch, blackish and buff marks on sides of head, neck and breast-band, and lacks the tarsal spurs of the male.
Taxonomy
The widely distributed populations show variations in plumage and about five subspecies have been designated:<p>Some races such as tschimenensis and yunnanensis are not widely recognized, the former included in the nominate form.The genetic divergence of these populations has been attributed to glacial cycles associated with the uplift of the Tibetan plateau.

Range and habitat
Tibetan snowcock are found on alpine pastures stony ridges above the tree line in the Pamirs of Tajikistan, Himalayas (from Ladakh to Arunachal Pradesh), Tibet, Pakistan and China. They are found in lower altitudes during winter or when there is heavy snowfall. In parts of its range there appears to be a clear separation of the distribution of this and the Himalayan snowcock while in others they appear to overlap.<p>Since the Tibetan snowcock has a large distribution range and no visible declines in population, it has been considered a species of "least concern" by the IUCN.

Cloud Cisticola
Cisticola textrix
Tiny, short-tailed, streaky, brown cisticola. Has a longer tail in non-breeding plumage. Found in fynbos and grassland habitats. Inconspicuous for most of the year. Usually seen when doing a flight display over its breeding habitat. The song consists of an ascending series of high whistles, followed by lower “chek” notes, which sometimes continue as the bird dives to the ground. Very similar to other small, short-tailed cisticolas, especially in non-breeding plumage. Best distinguished by voice.
Rusty-backed Thrush
Geokichla erythronota
A spectacular chestnut-backed thrush with striking white facial patches, black-and-white wings, and bold pied markings below. Juvenile shows buff streaks on crown and back and buff throat. Terrestrial, feeding on the forest floor singly or in pairs within the lowlands and low hills. Unmistakable within its limited range on islands of Sulawesi and Kabaena. Mournful song is a phrase of several high-pitched whistled notes, “deee-der-doo” or “deee-der.” Calls include “chak” notes and a high-pitched “peep” call.
Ringed Warbling Finch
Microspingus torquatus
Striking tanager of open woodland, consisting of two relatively distinctive subspecies. Distinguished from other warbling-finches in range by its black breast band. Nominate torquatus is a resident of the southern Bolivian Andes, especially open scrub and cactus forest of the dry valleys. Migratory pectoralis shows a thicker breast band and darker undertail coverts, and breeds in the Pampas, Monte, and northern Chaco dry forests in north central Argentina, dispersing north to lowlands of W Paraguay and SE Bolivia.
