The east-slope counterpart of the Glistening-green Tanager (Chlorochrysa phoenicotis) ranges widely from western Venezuela to northern Bolivia, where it is a generally uncommon inhabitant of mossy montane forest and its edges, principally at elevations between 900 and 2000 m. Three subspecies are recognized, all of which are predominantly green-plumaged, with an orange or rufous-colored rump, and orange-red neck-sides (not ‘ears’). They differ in the depth of the blue underparts in males, and two subspecies possess a black throat patch. Orange-eared Tanagers usually travel with mixed-species flocks and feed in the canopy or subcanopy of tall forest. The species name Chlorochrysa calliparaea comes from two Greek words; “khloros” which means green, and “kallipareos” which means beautiful-cheeked (Jobling 2010). The common name in Spanish is the Tangara Orejinaranja (Ridgely and Greenfield 2001, de Juana et al. 2012). Both the Latin binomial and the common name refer to the distinctive orange spots that appear on both sides of its neck near the ears.
