Samaipata, Santa Cruz, Bolivia.
Taxonomic status controversial; sometimes considered a race of S. subcristata, but the two differ in plumage, also slightly in voice, and in Argentina are narrowly parapatric with limited hybridization; further study needed. Described taxon S. griseiceps, from Bolivia (Cochabamba), with reduced white in crown and more buffish wingbars, widely believed to be based on juvenile specimens of present species, and thus treated as synonym of it, but now considered by some to represent a separate species on grounds of voice, plumage and distribution; further research required. Monotypic.
Breeds in Andes of W Bolivia (S from La Paz) and W Argentina (S to Neuquén and W Rio Negro); migrates E, as far as coast in SE Brazil and Uruguay, and as far N as NC Bolivia (S Beni).
