Black-crested Finch Lophospingus pusillus

Striking and distinctive small finch-like tanager of the Chaco desert from central Argentina to W Paraguay and S Bolivia. Prefers open cactus and thorn woodland, often near roads and settlements. Generally in pairs or small groups. Range overlaps with Gray-crested finch in southern Bolivia. Juveniles of these two species are similar but note Black-ctrested’s broad supercilium.
