Rock climbers are not the only acrobats that frequent cliffs. Raptors such as peregrine falcons nest and roost on lofty rocks and can be scared away from their chicks by careless climbers. Nationwide, nearly 60 crags have temporary climbing restrictions to protect these birds, but in many cases, raptors and climbers can coexist peacefully, says Kathryn Pyke with the Boulder Colo.-based Access Fund. Pyke is the author of a new report, Raptors and Climbers: Guidance for Managing Technical Climbing to Protect Raptor Nest Sites, which offers suggestions on protecting the birds without banning climbing altogether. Raptors & Climbers is available for free to resource managers, climbing representatives and educators; others may purchase the 27-page, illustrated booklet for $10 from the Access Fund, P.O. Box 17010, Boulder, CO 80308, by telephone 303/545-6772, or on their Web site at www.accessfund.org.
