Emerald-chinned Hummingbirds are small, short billed hummingbirds that are endemic to the highlands of Central America. They are most common between 1000 and 2200 meters and occur in humid montane forests. Emerald-chinned Hummingbirds forage quite low to the ground and males tend to be territorial when gathering nectar from flowers. In addition to their very short, straight bills, both sexes also have a conspicuous white spot behind the eye.
