The hummingbird that's faster than a fighter jet. A scientist has caught a hummingbird hitting a top speed twice that of the fastest fighter jet &ndash; at least relatively. The Annaâs hummingbird, now believed to be the fastest bird in the world relative to its size, can reach speeds of 50mph, or nearly 385 body lengths per second. That may seem slow compared with a Eurofighter's top speed of 1,320mph, but even at that speed the jet manages to cover just 39 body lengths per second.
