Hummingbirds are birds that comprise the family Trochilidae. They are among the smallest of birds, most species measuring in the 7.5–13 cm range. Indeed, the smallest extant bird species is a hummingbird, the 5-cm to about 20-mm Bee Hummingbird. They can hover in mid-air by rapidly flapping their wings 12–80 times per second . They are also the only group of birds able to fly backwards.[1] Their English name derives from the characteristic hum made by their rapid wing beats. They can fly at speeds exceeding 15 m/s . это про колибри )
