The bald eagle has appeared on the Great Seal of the United States, which is used in official documents, since 1782, when the design was finalized. The seal is made up of the eagle, an olive branch, arrows, a flag-like shield, the motto "E Pluribus Unum" and a constellation of stars.
Congress that same year designated the bald eagle as the the national emblem, and its image appears in a host of places, ranging from documents and the presidential flag to military insignia and U.S. currency, according to USA.gov.
But it had never been officially designated to be what many had just assumed it was — the national bird.
The bald eagle is indigenous to North America.
