Fastest wing-beats: Ruby-throated hummingbird
Hummingbirds are known for having incredibly fast wing beats, but there is one species that tops them all. The ruby-throated hummingbird has an average 55 wing beats per second during most of the year. However, during mating season, males perform courtship maneuvers for the females, including a dive display and, if the female perches, he will fly back and forth in front of her with a wingbeat rate of 200 per second! The bird even has Guinness record for its speed, which is probably quite a feather in its cap.
