Super Hummingbirds

Hummingbirds: they may be little, but they are some of Mother Nature's most amazing fliers. Their unique ability to fly up, down, left, right, backward, and even upside down is a trait seen in no other species of bird on Earth. Super Hummingbirds, a new Nature documentary airing tonight at 8 p.m. on PBS, gives us a never before seen look into the lives of these amazing little birds.
