It's not the first time Biden's been followed by a bald eagle. As vice president in 2015, one of the birds soared overhead during a Washington, D.C., appearance. He called it "a really good omen,” according to The Washingtonian.

Last September, also in Iowa, an alleged bald eagle flew over a Biden event that prompted the candidate to talk about his late son, Beau. He said he hadn't seen a bald eagle since Beau died in 2015, according to New York Magazine. He reportedly said of the bird, "Maybe that's my Beau."
