K. Armstrong, Public Affairs Specialist, Nat'l Forest Service: as of 6/8/21: BC areas reopen after unsuccessful nesting.

K. Armstrong, NF Ranger 7/29/20:

Following a 5 mo. closure to protect nesting eagles, the Roosevelt NF has reopened Eagle Rock.

“The BC eagles successfully raised 1 strong & healthy eaglet this year,” wildlife biologist Aurelia DeNasha, USDA FS. “2 chicks hatched initially, only 1 survived to fledge, which isn’t uncommon in birds of prey.”

Visits to the nest did not reveal the exact cause of death of the 2nd chick, but climber cooperation with closures are crucial to the eagles.

“Golden eagle pairs are most susceptible to disturbance when choosing a nest. These closures allow the birds to pick the best site for survival without impact of other factors, such as human presence. Once chosen, nest sites stays closed until the eagles fledge in late July,” said DeNasha.

After the eagles’ site selection was made, unused areas opened in Apr.

The annual nesting closures include popular rock climbing spots at Eagle, Blob, Bitty Buttress, & Security.

Effective through 7/31/20, the closures protect a long-established golden eagle nesting territory. Happy Hour, Bihedral & Riviera remain open as long as visitors stay out of the closed areas.

The Boulder Ranger District partners with BCC & AF to monitor nesting progress and to inform climbers about the importance of giving the eagles space to raise their young.

It is against federal & state law to disturb any nesting bird of prey. Only employees, volunteers, & wildlife professionals under an agreement with the FS enter nesting areas for monitoring purposes. This is for the integrity of nest & the safety of the eagles, those conducting surveys, & the public. Visitors help protect wildlife by respecting all closures & leaving immediately if you should accidentally enter one.

Perennial notice:
Eagle, Blob, Bitty Buttress, & Security will close 2/1 - 7/31 for nesting. Depending on updated information, the closure time can be shortened/lengthened.

Each year, BC raptor nesting area closures are in effect starting 2/1 through 7/31 at Eagle, Security, Blob, & Bitty Buttress. The area is monitored & closures are periodically lifted early (due to no active nest, nest site failure, or early fledging). This monitoring program is a partnership with the FS Boulder Ranger District, BCC, & Audubon Society. Check back periodically during times of closure for updates.
