There is little information on the behavior of Emerald-chinned Hummingbirds. It usually forages fairly low near the ground, although males sing from the understory to the midstory (Howell and Webb 1995). This hummingbird rarely venture into the open, and has a rapid flight (Howell and Webb 1995).
Little information, but these hummingbirds defend feeding territories at rich plant resources (Schuchmann 1999).
Little information. Emerald-chinned Hummingbird presumably is polygynous, as are most if not all species of hummingbirds (Schuchmann 1999: 509). Males sing in small leks.
Social and interspecific behavior
Emerald-chinned Hummingbird primarily is solitary, as is typical of hummingbirds.
