The small size and bee-like flight pattern of Bumblebee Hummingbird permits it to discretely forage in the floral territories of other species. Both sexes of this very small hummingbird have a rounded tail, and males have a stunning pink throat. Bumblebee Hummingbirds inhabit humid and semi-humid forests, pine-oak woodlands, and neighboring shrubby areas. They spend most of their time in the lower and middle levels of the forest. During courtship displays, males hover in a horizontal position with their tails held vertically. In flight and during displays, the wings of Bumblebee Hummingbird emit an audible insect-like sound.
