Ovenbirds (Furnariidae)
Chaco Earthcreeper (Upucerthia certhioides) - HBW 8, p. 249
French: Upucerthie du chaco
German: Roststirn-Erdhacker
Spanish: Bandurrita Chaqueña
Taxonomy: Anabates certhioides d’Orbigny and Lafresnaye, 1838, Corrientes, Argentina.
Sometimes placed in a separate genus Ochetorhynchus along with U. ruficaudus and U. harterti; closest to latter, with which may form a superspecies, or the two may be conspecific. Differs from other congeners for which relevant data available in having pale blue eggs (not white) and more flexible nest-site placement. Racial variation may be partly or entirely clinal, and one or more of the races possibly not tenable; quantitative study of plumage coloration required. Three subspecies recognized.
