The Chestnut-eared Aracari is a medium-sized toucan of the Amazon Basin of South America. Very common in its range, it has the widest distribution of any of the aracaris. Although it prefers forest edges and young forest, the chestnut-eared aracari can be found in a wide variety of landscapes, many of which are characterized by standing or flowing water, and is often found around gardens and human dwellings. It is frequently encountered in pairs or small groups, especially in fruiting trees. Chestnut-ears are highly social, active, and mischievous birds known for their inquisitive, goofy personalities, and constant investigation of their surroundings.
