It also occurs on brushy slopes, overgrown pastures, and páramo and occasionally in denser subtropical forest. In elevation it ranges between 2,300 and 4,200 m (7,500 and 13,800 ft) but mostly occurs between 2,800 and 3,500 m (9,200 and 11,500 ft).

Steinbach's Canastero
Pseudasthenes steinbachi
A plain, chunky canastero of the Monte desert region in Argentina. Often in low, dense vegetation. From other canasteros by its relatively plain gray head. From similar Patagonian Canastero by Steinbach’s rufous wing and tail feathers. Prefers thorn forest and open woodland. Song a fast series of notes, lower and more gravelly than the similar Patagonian Canastero, slightly accelerating over the ~2 seconds in which it is given.
Cinereous Becard
Pachyramphus rufus
This small becard is fairly widespread in lowlands and foothills in northern South America. Males are gray, slightly paler below, with contrasting black cap and relatively plain wings. Females mostly rich rufous with paler lores and a whitish belly. Not a forest bird; found in more open woodland, edges, and second-growth. Usually seen in pairs.
Silvery-cheeked Hornbill
Bycanistes brevis
Big, spectacular, black-and-white hornbill. Both sexes show a pale bill, with a large casque that is larger in males and smaller in females. In flight, the wings are mostly black with a small white patch below, and there are white corners to the tail. Found from low to high elevations in forest, and adjacent areas of lush woodland and cultivation. Usually in pairs or small groups. The loud calls are honking and yapping notes that are often given in a quick series. Similar to Black-and-white-casqued Hornbill, but has a paler bill, and much less white in the wings. Also reminiscent of Trumpeter Hornbill, but larger, with a bigger bill, and less white in the wings and on the belly.
