The bills of nominate subspecies adults have a yellow line at the base and a mostly black mandible. The maxilla has a black stripe on the culmen, a triangle of black narrowing toward the tip, orange-yellow between them, and black and ivory markings on the edge that look like teeth. Adult males have a black crown and upper nape, a chestnut lower nape, a dark green back, and a red rump. Voice: The chestnut-eared aracari's principal call is a "piercing and high-pitched....'sneeep' to longer 'psheee-eeep'". It also makes a "single 'tekk' call, low 'eeee-eee' call with 4 whistled 'weet' notes and a 'pyeee-tyee-tyee-tyee-tyet'."
