The white-eared hummingbird is 9 to 10 cm (3.5 to 3.9 in) long. Males weigh an average of 3.6 g (0.13 oz) and females 3.2 g (0.11 oz). Adults of the three subspecies are very similar. Their bills are straight; males' are red with a black tip and females' are mostly blackish with some red to orange at the base. Males of the nominate subspecies in breeding plumage have a metallic violet or bluish violet forehead, a mostly black face with a wide white stripe behind the eye, and a dull black crown. Voice: The white-eared hummingbird's song is "a tedious, metallic chipping chi'tink chi'tink chi'tink ..., or chi'dit chi'dit chi'dit ..., or simply tink tink." Its calls have been described as "fairly hard, dry chips, at times repeated steadily, may break into short, quiet gurgles" and "a sharp metallic tchik or tink".
