Hummingbirds are some of the smallest members of the class Aves. They can flap their wings at the incredible rate of 60 to 80 beats per second and have the ability to hover and actually fly backwards. Hummingbirds primarily dine on nectar, but also eat small insects. Due to their hyperactive metabolism, an adult hummingbird must eat its weight in nectar everyday.
