The only predominantly brown hummingbird in the violetear genus, brown violetears have brownish-bronze upper parts and a diagnostic violet-blue ear patch. Found across a broad range of humid forest and forest edge from Guatemala south through Venezuela, Colombia, and Brazil to Bolivia. Inhabiting elevations from lowland to 2,000 meters, they are found in forest interior, forest edge, and gardens. Despite relatively drab plumage for a hummingbird, the violet ear patch glitters vividly in direct sunlight.
