The hummingbird is the only bird that can fly backwards and sideways. With their unique wing structure, hummingbirds are able to hover in mid-air and rapidly beat their wings up to 80 times per second, allowing them to maneuver in any direction with precision. This unique skill is essential for feeding on nectar from flowers and avoiding predators. Hummingbirds are found primarily in Central and South America, although some species can be found as far north as Alaska.
