Outgoing Biden signed a bill at the end of his presidential career to officially designate the bald eagle as the national bird of the United States.

As the spiritual symbol of a country, the national bird carries national culture, history and values.

As the national bird of the United States, the bald eagle symbolizes the freedom, strength and independent spirit of the United States.

The majestic appearance of the bald eagle, its sharp eyes, strong body, broad wings and sharp talons, all symbolize the tenacity and strength of the United States.

In particular, its flying posture gives people a sense of fearlessness and courage, which is closely related to the history of resistance to British rule during the American Revolutionary War.

Benjamin Franklin, one of the founding fathers of the United States, once opposed the bald eagle as the national bird, believing that the turkey was more in line with the character and spirit of the United States.
