The yellow-eared toucanet (Selenidera spectabilis ) is a species of bird in the family Ramphastidae found in humid forests of Central America and the Chocó. Cassin's aracari is an alternate name for the yellow-eared toucanet. A somewhat aberrant member of the genus Selenidera, it is relatively large (total length approximately 38 cm ) and the plumage of the sexes only differ in that the male has a yellow auricular streak, while the female has a brown crown. It weighs 175-245 grams (6.2-8.7 oz.)
