English to Greek Other Zoology

Hummingbirds are birds in the family Trochilidae, and are native to the Americas. They can hover in mid-air by rapidly flapping their wings 12–90 times per second (depending on the species). They can fly backwards, and are the only group of birds able to do so.[1] Their English name derives from the characteristic hum made by their rapid wing beats. They can fly at speeds exceeding 15 m/s (33 mph).
