Bar-winged Cinclodes (Cinclodes fuscus) - HBW 8, p. 253

Taxonomy: Anthus fuscus Vieillot, 1818, “Less rare in the fields of Montevideo and Buenos Aires than in Paraguay..
“Less rare in the fields of Montevideo and Buenos Aires than in Paraguay.”Has been thought by some to form a superspecies with C. comechingonus and C. pabsti; often treated as conspecific with former, their breeding ranges evidently not overlapping. Sometimes considered also to include C. olrogi as a race, that taxon being very similar to races riojanus and yzurietae of present species. Proposed race paramo (from Nariño, in SW Colombia) described as differing from oreobates in having shorter wings and tail, but overlap in measurements is extensive. Further, within area assigned to race albiventris, plumage varies clinally from darker in N to paler in S; also, birds from drier areas are whiter than those from humid slope of Andes, and are potentially the “true” representatives of that race, leaving presumably the name longipennis (proposed for N populations) available for humid-slope birds; described race rivularis, of Junín region of Peru, supposedly differs from latter in less rufescent back, paler flanks and less heavily margined breast feathers, which matches some specimens from Junín region, but its type locality (Maraynioc) is at or near humid E slope; whether these two described forms are valid entities requires further study. Nine subspecies recognized.
