There is little information on the behavior of Coppery Metaltail. Often perches on the top of shrubs (Fjeldså and Krabbe 1990). Presumably catches arthropods with short flycatching sallies, as does the closely related Neblina Metaltail (Metallura odomae) (Parker et al. 1985).
Little information. Coppery Metaltails frequently are observed in intraspecific chases, which may be acts of territorial defense.
Little information. Coppery Metaltail presumably is polygynous, as are most if not all species of hummingbirds (Schuchmann 1999: 509).
Fjeldså and Krabbe (1990) describe an apparent courtship display, in which the male "repeatedly bounces 1 m up and down, or alternates rapidly between 2 perches in front of female".
Social and interspecific behavior
Coppery Metaltail usually is solitary, as is typical of hummingbirds.
No documented reports of predation on Coppery Metaltail?
