rufous-backed robin Turdus rufopalliatus

Handsome thrush of tropical woodlands, gardens, and forests in lowlands and lower foothills of West Mexico with isolated populations in Mexico City and Oaxaca City. Feeds on ground, in fruiting trees and bushes and at times in small flocks, often with Great Kiskadees and Social Flycatchers. Like most thrushes, can be rather wary. Note rusty back and breast, blue-gray head, and yellow bill. Some birds in coastal Nayarit ("Grayson’s Thrush") notably paler and duller overall; mainly seen around San Blas, where greatly outnumbered by typical bright birds.
