The bald eagle, a symbol of the United States' power and strength for more than 240 years, is now officially the national bird of the country.
The bald eagle has been a national emblem in the US for years, appearing on the Great Seal of the US - used on US documents - since 1782.
The bald eagle is indigenous to North America.
The Great Seal of the United States is a national symbol used in the official documents such as treaties and commissions.
The final design was approved in 1782 and includes a bald eagle, an olive branch, arrows, a flag-like shield, the motto E Pluribus Unum (which translates to "out of many, one") and a constellation of stars.
The bald eagle is also protected under the National Emblem Act of 1940, which makes it illegal to sell or hunt the creature.
