The national bird of the United States is the bald eagle. Chosen as a symbol of freedom and strength, the bald eagle was designated as the national emblem in 1782 because of its majestic appearance and unique characteristics. It is a large bird of prey known for its striking white head and tail feathers, contrasting against a dark brown body. Found primarily in North America, the bald eagle primarily inhabits areas near large bodies of open water, where it can hunt for fish, its main food source. The bald eagle's significance is reflected in its presence on the Great Seal of the United States, representing patriotism and resilience.
