The sandy gallito is a year round resident of the eastern slope of the Andes of Argentina from southwestern Salta Province in the north to Río Negro Province in the south. For most of that range it is found up to 3,500 m (11,500 ft) and in Salta up to 4,000 m (13,000 ft). Its habitat is subtropical or tropical dry shrubland characterized by sparse vegetation on sand and gravel, dry washes, and ravines.

Yellow-fronted Canary
Crithagra mozambica
A small, short-tailed yellowish finch. It is bright yellow below with a yellow eyebrow and cheek patch. The upperparts are grayish green with streaks. Females are duller colored than males. Found in dry grassy areas and brushy areas, often in flocks with other species. The pleasant song is a rapid series of high-pitched musical chips. Native to Africa, introduced to the Hawaiian Islands, Mauritius, and Puerto Rico.
Stripe-backed Bittern
Botaurus involucris
Very small, striped buffy heron of wetlands and lake edges with dense reeds and rushes. Boldly striped back pattern is distinctive. In flight shows contrasting broad rusty trailing edge to wings. Usually seen as single birds hidden in reeds or making short flights low over reeds or across patches of open water. Clambers easily and stealthily; hunts from perches over water, where sits patiently before stabbing at fish. Mostly silent.
Cape Grassbird
Sphenoeacus afer
A chunky, streak-backed warbler with a rusty head and wings, a ragged rufous tail, and black moustache stripes. It avoids woodland and trees, preferring rank areas with long grass, scrubby edge, and wet heathland (fynbos). It hops and clambers through dense brush and thickets, then flies low on rapidly-beating wings in labored flight to the next bush, immediately diving into cover. But it will also perch on prominent tall shrubs, like proteas, and sing its melodious tinkling jumbled song that starts softly and gets progressively louder. It also has a distinctive flat mewing “meeeeep” call. The Moustached Grass-Warbler is similar to the Cape Grassbird, but it has a plain unstreaked back, a broad black tail, and a pale eye.
