White-throated Earthcreeper Upucerthia albigula

The White-throated Earthcreeper resembles other Upucerthia earthcreepers, but has a stouter bill and more rufescent remiges and wing coverts. It occurs in a small area on the western slope of the Andes between central Peru and extreme northern Chile. Here it is found in arid montane scrub, where it probes and gleans the ground for arthropods. The White-throated Earthcreeper overlaps geographically with the similar Plain-breasted Earthcreeper Upucerthia jelskii, but the Plain-breasted is paler and more uniform below, has browner wings and a less distinct superciliary, and generally occurs at higher elevations.
