What are hummingbird's relatives?

Their name comes from the fact that they flap their wings so fast (about 80 times per second) that they make a humming noise. Hummingbirds can fly right, left, up, down, backwards, and even upside down. They are also able to hover by flapping their wings in a figure-8 pattern. They have a specialized long and tapered bill that is used to obtain nectar from the center of long, tubular flowers. The hummingbird's feet are used for perching only, and are not used for hopping or walking. Their heart is able to beat up to 100 times per second.
