|Hummingbirds are found only in
the western hemisphere and probably have the most intensely iridescent
feathers known in birds, with colors ranging over the whole visible light
spectrum. They are the only bird that can fly backwards and even upside
down. Depending on the species and the size, they flap their wings between
18 to 200 times per second and often all you see is a blur of wings.
