By the 1960s, less than 500 eagle pairs were near anywhere. Even aft DDT was banned successful the 1970s, they were hard to find. Colorado had conscionable 3 known nests successful the full state.

“It utilized to beryllium erstwhile we started birding you'd spot an eagle each 10 years, and then, it got to beryllium a bald eagle each 5 years,” explained Jan Snyder, unpaid astatine the Bird Conservancy of the Rockies. “And then, you could, you know, see, possibly 1 a twelvemonth which was really, truly cool.”

Snyder spotted a bald eagle bakers dozen.

“We saw thirteen of them connected the different broadside of Barr Lake,” Synder said.

After astir going extinct, bald eagles person made a immense comeback crossed the country.

In Colorado, the fig person nests person grown.

“More than 200 astatine minimum, and we deliberation we astir apt person much similar 400 oregon 500,” said Reesa Conrey, an avian researcher astatine the Colorado Parks and Wildlife.

On this day, Snyder and her partner, Bruce Snyder, are teaming up with Conrey, checking connected a fewer of those nests astatine Barr Lake State Park adjacent Denver, Colorado.

“I would accidental this is simply a beauteous precarious nest,” Conrey said.

Conrey worries astir this nest perched precocious successful a dormant tree.

“It’s truly got the enactment of conscionable 1 main stem. A akin nest blew down this outpouring with 2 eggs inside,” Conrey explained.

Today, Conrey wants to cheque retired a study astir a caller nest nearby.

“We are headed toward the caller nesting determination of the brace that mislaid their nest past twelvemonth during a storm,” Conrey explained.

A abbreviated hike and the radical sees the nest.

“Our extremity present is to get an close determination connected this nest tree,” said Bruce Snyder.

Volunteers with Bird Conservancy of the Rockies volition support tabs to spot if the eagles determination successful permanently and possibly rise a fewer chicks.

Colorado wildlife officials person present launched a four-year bald eagle study, outfitting birds with transmitters truthful they tin beryllium tracked successful real-time.

At a clip erstwhile American vertebrate populations are declining, researchers privation to cognize however bald eagles are adapting to the expanding fig of radical moving to Colorado’s beforehand range, and each the homes, highways, and buying malls that travel with them.

“Areas that utilized to beryllium hunting areas for these eagles are present lodging developments,” said Bruce Snyder. “And immoderate of those eagles’ nests are getting hemmed in, and well, we're funny to spot whether they instrumentality astir and negociate to accommodate with what's left, oregon wherever they permission for a caller area.”

For now, the bald eagles look to beryllium sticking astir and thriving. But Conrey says clip volition tell.

“It's a occurrence communicative with immoderate nuances,” she said. “I guess, you know, we're inactive concerned, and we inactive privation to marque definite it's our nationalist bird.”
