Ovenbirds (Furnariidae)

Plain-breasted Earthcreeper (Upucerthia jelskii) - HBW 8, p. 247

French: Upucerthie de Jelski German: Fahlkehl-Erdhacker Spanish: Bandurrita de Jelski

Taxonomy: Coprotretis Jelskii Cabanis, 1874, Junín, Peru.
Closest to U. albigula and U. validirostris. Has been considered to form a superspecies with latter, and may be conspecific; considered together, the two exhibit a stepped cline in plumage coloration (increasingly rufescent to S) and perhaps a smooth cline in measurements, and songs sound very similar (although written descriptions differ somewhat); on the other hand, they appear to overlap in range in S Bolivia (Potosí); further study needed. Vocally distinctive race pallida possibly a separate species. Three subspecies recognized.
