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 is the only bird able to fly backwards (under its control). It is not aerodynamically possible for most birds to fly backwards. However, some are able to turn somersaults or cartwheels in mid-air, as a means of better pursuing or catching their prey. One example of this is the Roller Pigeon, which uses the technique to catch insects in flight.
