Behavior

Behavior

Male Coppery-headed Emeralds frequently ascend to the forest canopy, females (but not males) often are in forest understory, and both sexes occur "at all levels" at forest edges, at gaps in the forest, and in other semiopen sites (Stiles and Skutch 1989).

In addition to foraging for nectar at flowering trees and shrubs, this emerald gleans small arthropods by gleaning from foliage at all forest strata, and by sallying from a perch (Stiles 1999).

Sexual Behavior

Little information. Coppery-headed Emerald presumably is polygynous, as are most if not all species of hummingbirds (Schuchmann 1999: 509).

Male Coppery-headed Emeralds form small leks, at which males "perch at middle heights in trees around a gap or in scattered pasture trees, singing and chasing one another" (Stiles and Skutch 1989).

Social and interspecific behavior

Coppery-headed Emerald usually is solitary, other than in the male singing groups (see Sexual Behavior).

Coppery-headed Emerald is subordinate to other species of hummingbirds (Feinsinger 1976).

Predation

No reports of predation on Coppery-headed Emerald?
