Quick Answer. Hummingbirds fly backwards, and they are the only birds capable of doing so. When using this unique ability, hummingbirds may reach speeds of 25 to 30 mph as they go. These birds have flexible wings that they can rotate in swift circles to help fly in reverse.
A hummingbird flies very differently from other birds, who tend to use their wings to flap or soar. A hummingbird, however, flies by moving its wings in a figure-8 type shape, allowing it to move up, down, side to side, and even backward! Hummingbirds also flap their wings famously fast â enough that they even sometimes buzz! Hummingbirds flap their wings quickly because it helps them to hover, which lets them move from flower to flower and eat up all the delicious nectar they need !
