Raptor Breeding Grounds Prompt Climbing Advisory at Colorado National Monument

GRAND JUNCTION, Colo. — The Colorado National Monument has issued a seasonal raptor advisory effective through July 31, 2025, temporarily restricting access to key climbing routes to safeguard nesting birds of prey.

The primary focus of the advisory is Otto’s Route, a popular climbing path on Independence Monument, which has been closed to all climbing and off-trail activity during the breeding season.

“We’re asking climbers and visitors to respect these closures and help ensure the survival of these remarkable birds,” said a spokesperson for the Colorado National Monument.

March Through July: Breeding Season in Focus

The advisory corresponds with the typical raptor breeding season, which runs from March 1 through July 31. During this period, falcons, hawks, and eagles may establish nests along cliff faces and rocky outcrops, many of which intersect with climbing routes.

Officials warn that disturbances can lead to nest abandonment or failed fledging, which can have long-term effects on raptor populations.

Broader Caution Urged for Climbers

While Otto’s Route is the only area explicitly closed, the Monument warns that raptor nests may exist near other climbing routes. Climbers are urged to remain observant and back away if they notice territorial or agitated bird behavior, which could signal an active nest nearby.

“We don’t mark every nest site for safety reasons, so climbers need to be part of the solution by staying alert and acting responsibly,” officials said.

Conservation in a Climber’s Playground

The Colorado National Monument, known for its iconic red rock canyons and technical climbing routes, walks a careful balance between outdoor recreation and habitat conservation. Raptors such as peregrine falcons and golden eagles are known to nest throughout the Monument, and federal protections under the Migratory Bird Treaty Act reinforce seasonal access limits.

Officials emphasize that the advisory is temporary and will be lifted at the end of July barring any unexpected late-season nesting.
