He's been showing up, trading squawks with the captive bird, Olivia.
Zoo workers believe the bald eagle that shows up to visit 6-year-old Olivia is a male.
A zoo employee noticed the rare bird checking out Olivia from a nearby tree.
"The wild bald eagle has been coming in about a week and a half now, coming in the mornings, the afternoons, landing next to this eagle exhibit and vocalizing back and forth with our female bird," said Donald Zeigler, the zoo manager.
But even if the other bird is a male, there won't be any love connection any time soon.
Zoo officials said there is no way into this exhibit and sadly, Olivia isn't healthy enough to be released.
"Olivia is an injured bird," Ziegler said. "We would all like to see out in the wild. She is not going to be able to survive out on her own."
But even though there won't be any eagle eggs hatching, interest in the bird is soaring.
When the zoo posted video of the visiting bald eagle on the internet, bird fans with cameras soon began popping up near Olivia's exhibit, hoping for a shot of her rare friend.
"It's kind of a romance story, isn't it?" said Bob Smith of Costa Mesa. "We all love that kind of thing."
