Hummingbirds

Hummingbirds are birds of the family Trochilidae, and are native only to the Americas. They are known for their ability to hover in mid-air by rapidly flapping their wings 15–80 times per second (depending on the species). Capable of sustained hovering, the hummingbird also has the ability to fly backwards, being the only group of birds able to do so.Hummingbirds may also fly vertically or horizontally, and are capable of maintaining a position while drinking nectar or eating tiny arthropods from flower blossoms. Their English name derives from the characteristic hum made by their wings
