French: Conophage à oreilles blanches German: Rostbrust-Mückenfresser Spanish: Jejenero Orejudo

Taxonomy: Turdus auritus J. F. Gmelin, 1789, Cayenne.
See page 734. Possibly closest to C. melanops. Precise range limits of most races unclear. S of Amazon, marked variation in plumage and also in voice: abrupt change of pace and note structure (and, thus, sound quality) across R Madeira/Tapajós interfluvium. Race snethlageae distinctive: possibly best treated as a separate species, with pallida as a race or a synonym thereof, representing only one extreme of a clinal range of variation. Some confusing variation within range of australis, as some specimens from R Purús (W Brazil) have appearance approaching that of.. View all taxonomy...
