Cinereous Ground-Tyrant

Large, long-tailed sparrow with unique color pattern: gray body, fairly bright greenish wings and tail, rufous crown, and white throat. Favors disturbed areas in montane forest and open slopes for breeding. In winter, usually found in dense thickets or mesquite in desert washes. Forages on the ground or in dense shrubs primarily for seeds and insects. Rarely visits feeders. Listen for unique nasal call note.

An unusual small sparrow of dry country. Males have a yellow head and underparts and a chestnut back. Females are much plainer, sandy brown on the back and pale below with a yellow wash. Found in dry thorn savanna, thorn scrub, and semi-desert. Nests colonially, and usually found in flocks, sometimes large, and sometimes mixed with other bird species. Similar to Arabian Golden Sparrow, but almost does not overlap in range. Male is separated by his chestnut back, and females by being duller and less yellow. The common calls include chirps and chatters. 

Distinctive and striking tinamou, nearly endemic to Argentina, from northern Patagonia through the Monte desert region. Prefers open, rocky habitat. In the northern chaco replaced by similar Quebracho Crested-Tinamou. Often found by its three-part whistled song: a “twee-tyoo-too” similar to but less emphatic and more consistently pitched than Red-winged Tinamou.
