White-eared Hummingbird typically forages at low to mid levels (Howell and Webb 1995).


White-eared Hummingbird is territorial (Lyon 1976). At one site in Mexico, the mean territory size for males as 431.6 ± 88.5 m2 (n = 41) (Lyon 1976). White-eared Hummingbird defends its territory not only against other members of the species, but also against smaller bodied species such as Bumblebee Hummingbird (Atthis heloisa), and against at least some species that are slightly larger, such as Broad-tailed Hummingbird (Selasphorus platycercus) (Moore 1939, Lyon 1976). White-eared Hummingbird is subordinate, however, to much larger species of hummingbirds, such as Magnificent Hummingbird (Eugenes fulgens) and Blue-throated Hummingbird (Lampornis clemenciae) (Moore 1939, Lyon 1976). Nonetheless, White-eared Hummingbirds employ "secretive low approaches" to forage at stands of Penstemon within territories defended by these two larger bodied species (Lyon 1976).

Sexual Behavior

White-eared Hummingbird sings in small leks, of up to seven individuals (Dickey and van Rossem 1938, Skutch 1940). At one such site, seven singing males were around the edges of an open pasture, with the most distant two individuals ca 180 m apart; another lek contained five males, each of which was within 27-30 m of its neighbors (Skuth 1940). Other males apparently sing solitarily (Skutch 1940).

White-eared Hummingbird presumably is polygynous, as are most if not all species of hummingbirds (Schuchmann 1999: 509).

Social and interspecific behavior

Away from leks, White-eared Hummingbirds are solitary, as is typical of hummingbirds..
