"We’re gonna win Iowa," tweeted Christina Freundlich, Biden's Iowa deputy state director for communications.

"great advance work," added CNN political analyst and former Clinton White House press secretary Joe Lockhart.

Washington Post reporter Matt Viser noted that at least one vulture has been spotted at a previous Biden event.

"The Biden campaign no doubt likes this omen a bit better," he tweeted.

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."
