They range in size from the smallest birds on earth to several quite large species—in length from 2 to inches and in weight from to ounce. Hummingbirds flap their wings from 12 to 90 times per second (depending on the species) and are the only birds able to fly backwards. Normal flight speed for hummingbirds is 25 to 30 mph, but they can dive at speeds of around 60 mph.
