The Antillean crested hummingbird (Orthorhyncus cristatus) is a species of hummingbird in the family Trochilidae. You will most likely see these tiny birds fluttering around a variety of native flowers, eating nectar, although they also eat insects. They use absurd amounts of energy by moving their wings so fast, that is the reason they need to eat all day. Otherwise they would starve due to the loss of too many calories.
Their common family name is derived from the distinct humming sound that their fast beating wings make (their wings can beat as fast as 80 beats per seconds). The cup nest is placed on a branch in vegetation.
