With spring approaching, eyes at one office near DuBois are turning toward a pair of bald eagles once again.

We went looking for the birds and the bird watchers.

Some wildlife teachers and nearby employees say they’ve been watching the nest closely for a few years now.

“I’ve never thought about bald eagles at all until the nest was here,” says Kristy Smith, who works nearby.

But now, the Unilec employees are hooked. Without eagle eyes of their own, they use a scope to spot the flying couple.

“She’s obviously laid an egg or more than one egg. We can’t see from here,” says Smith.

“She’s been sitting on the nest now for a few weeks and he brings her food,” says Len Hawkins, who works nearby.

For four seasons, Penn State DuBois wildlife instructor Emily Thomas says she’s brought her animal identification class to see the nest.

Thomas says it used to be smaller, when it was home to great blue herons.

“There were scattered nests all throughout the trees and the bald eagles actually built on to one of those nests and that displaced the herons,” says Thomas.

“We got out and we looked for about five minutes to look and there was a female eagle on her legs in the nest,” says freshman Tyler Ferguson.

“She just sits down in it and you can kind of see the top of her head sometimes and the male is flying around,” says freshman Corinne Blossfeld.

Thomas says eagles used to be rare because the pesticide DDT thinned their egg shells, but their numbers have soared since being re-introduced in Pennsylvania in the ’80s.

She believes this pair must be at least four or five years old since they’re having young, and that they fledged three young in 2014 and two last year.

“They just look like a ball of gray fuzz for a while,” says Smith.

“When one of them brings food back, you’ll see their heads bop up and down and as they get bigger you get to see them, they turn black,” says Hawkins.

“I think it’s actually pretty cool because I’ve never gotten to see eagles out in the wild,” says Ferguson.

Thomas says even though the baby eagles are small, they grow to full size before leaving the nest.  We did not spot the eagles on Thursday, but we did get some pictures from bird watchers.
