Behavior Movement Following breeding the coppery-headed emerald moves to the lower parts of its elevational range. Feeding The coppery-headed emerald forages for nectar at a wide variety of flowering plants, shrubs, and trees; examples include those of genera Besleria, Cavendishia, Clusia, Guarea, Pithecellobium, Quararibea, Satyria, and Inga. In addition to nectar, it gleans small arthropods from foliage and captures them by hawking from a perch. Breeding The coppery-headed emerald's breeding season extends from October to March and may vary within that window from year to year. Males court females at leks in small groups, singing from a perch and chasing other males. Females construct a small cup nest of plant down and tree fern scales bound with spiderweb with some moss and lichen on the outside. It is typically placed between above the ground in the understory or along an edge. The clutch size is two eggs; the incubation period and time to fledging are not known. Vocalization The coppery-headed emerald's song is a "high, thin, twittering and warbling." Its call has been described as "a high, thin, liquid quip or quit or rapid high sputtering in chases." Status The IUCN has assessed the coppery-headed emerald as being of Least Concern. Its population is estimated to be at least 20,000 mature individuals and stable.
