Released on Independence Day, this stamp continued those symbolizing the nation's war effort and its goal of victory.
The bald eagle, Haliaeetus leucocephalus, is the national emblem of the United States. It is protected by law. Nevertheless, some large eagles are killed by farmers and gamekeepers or captured for use in falconry. As with other birds, the bald eagle has been affected by widespread use of pesticides that, when ingested, can weaken eggs. Eagles are predatory birds that have been the symbol of courage, immortality, and power since ancient times.
All eagles have large, heavy, hooked bills and strong, sharp claws called talons. The bald eagle is not really bald, but is so-named because of its white head. Eagles prey on small creatures: birds, fish, rabbits, other rodents, and snakes. They have very keen eyesight and hunt while soaring high in the air or watching from a high perch. An eagle's aerie, or nest, typically is high in a tree or on a rocky ledge, where it cannot be reached easily by other species, including humans. This precaution is important because young eaglets remain helpless for a long period.
