People are "flocking" to industrial Cleveland to see a spectacle of nature not visible there in more than a century.

Bald eagles are now roosting along the Cuyahoga River in the Cleveland Metroparks' Ohio and Erie Canal Reservation.

They're a sign of the renewed health of a river once believed to be dead.

In the shadows of train trestles and high tension wires, park spotters have counted as many as 15 eagles along one stretch of the crooked Cuyahoga River.

The sightings are bringing people to the park, including photographer Cerena Cernik, who saw 8 eagles during her visit.

"When we were completing the walk, the people kept on moving and a few more just flew by and I was like, 'This is cool.' It's hard to leave the area because it's so neat," Cerena told us.

There is a nesting pair in the park. But the river is what attracts the eagles, so keep your eyes peeled.

"On any given day you can see them all up and down the corridor of the Cuyahoga. It doesn't have to be right here by the nest," says Karen Lakus from the Cleveland Metroparks.

Cleveland Metroparks is leading guided hikes to see the eagles, so check their website for days and times. Like Cerena, you won't regret it.

"There's a lot of nature here which is kind of neat with all the industrial and the trains going by. It's pretty remarkable for my first time being here," she says.
