Visitors to the Oregon Zoo in Portland have noticed a new addition to the zoo perched among the tall Douglas firs in the park.

For the last week and a half, a pair of wild bald eagles have taken up residency in the zoo's Great Northwest area.

“They’ve been very visible and are making a lot of noise,” zoo curator Tanya Paul said in a news release. “They’re acting as though they nested here or somewhere nearby, which is exciting because we haven’t seen eagles nest this close to the zoo before.”

The two birds have white heads and tails of adult bald eagles, meaning they’re at least 4 or 5 years old, according to the zoo.

Paul said the pair may be caring for a recently fledged juvenile eagle that also has been seen nearby.

If that is the case, the birds may stick around through the summer, until their offspring is fully fledged and ready to make its own way in the world.

“These birds are talking a lot,” Paul said. “And they have definitely perched in places where they can see Jack and Reetah, the two bald eagles in our Eagle Canyon habitat.”

Jack and Reetah are rescue birds with injuries that left them unable to survive in the wild that are distinguished from each other by their eyes: Reetah is missing her left eye, while Jack is missing his right.
