A hummingbird is a small brightly coloured bird found in America, especially Central and South America. It has a long thin beak and powerful narrow wings that can move very fast. COBUILD Advanced English Dictionary.
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.
