Version: 1.0 — Published February 10, 2012


Distinguishing Characteristics

Earthcreepers (Ochetorhynchus, Geocerthia, Upucerthia, and Tarphonomus) are large terrestrial ovenbirds (Furnariidae), with long bills and tails. The Striated Earthcreeper is a dark-colored, relatively straight billed earthcreeper. This species also has heavily streaked underparts and the wings are extensively rufous.

Similar Species

The Striated Earthcreeper overlaps geographically with Plain-breasted Earthcreeper (Upucerthia jelskii), although Plain-breasted typically occurs in more open habitats, and often at higher elevations. Striated Earthcreeper easily is distinguished from Plain-breasted by the heavily streaked underparts and the rufous wings, and by the straighter bill.  distinguish this from Plain-breasted Earthcreeper. These features also serve to distinguish Striated from White-throated Earthcreeper (Upucerthia albigula) in the restricted area where both species occur.
