Bald eagles can get up to three feer tall and can have a wing span of eight feet.  Adult eagles have a white head and tail with a dark boday, yellow eyes, bill and feet.  Young eagles are light brown and do not do not develope white feathers until they mature at about five years of age.  As with most predatory birds, females are larger and heavier than males.  Their feet have four talons but one is facing the opposite way as the other three.  This makes it easier for and eagle to grasp prey and perch on branches.  The bottom of their toes are covered with small, rough bumps that help gasp and hold prey.  The bill is curved at then end, which allows it to tear its prey into smaller pieces.  Southern birds are smaller than birds in the north.
