The Sharp-billed Canastero is a resident breeding species in central and southern Argentina and the eastern border Andean cordillera of Chile; some birds migrate north as far as the southwest border of Paraguay, the southern border region of Bolivia, and western Uruguay, in the austral winter. Its natural habitats are subtropical or tropical dry shrubland, subtropical or tropical high-altitude shrubland, and temperate grassland.
The Lesser Canastero is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.
Lesser Canastero was seen in this area. Walking further along the road towards el Salto, Golden-billed Saltator and Chalk-browed Mockingbird were seen in roadside scrub. A couple of km further along, the 3rd canyon along (almost wide enough to drive a car down) seemed to have good habitat and some interesting birds had been seen there before. All I saw of interest though was Patagonian Canastero. I saw 32 species including 4 lifers. More
Cinclodes, 6 Grey-flanked Cinclodes, 3 Lesser Canastero (at the HQ), 5 Moustached Turca, and 1 nice Magellanic Tapaculo among the rocks around the edge of the bog at Yeso. Lots of Ground-Tyrants (10 White-browed, 1 Ochre-naped, 1 Black-fronted), 10 Greater Yellowfinch at the HQ, and lots of Sierra Finches, including the lifer Grey-hooded (20 seen). The next day we headed to some small lakes at Leyda near the coast. More
