The Marvelous World Of Hummingbirds (PHOTOS)

In honor of Earth Day, we've teamed up with National Geographic to bring you photos that celebrate the beauty of nature, as we did early this week with a look at national parks. This time, we're focusing on hummingbirds, the marvelous bird that hovers in flight. There are about 330 species of hummingbirds, and here you'll find a diverse, colorful range. Take a look, and vote for your favorite hummingbird!
