Peregrine falcons halt climbing at rumney rocks

Rock climbers seeking a challenge at Rumney Rocks, New Hampshire, will face a temporary setback. Portions of the famed climbing area have been closed due to the presence of nesting peregrine falcons, a move intended to protect both the endangered birds and the climbers themselves. The closure, affecting sections of the Main Cliff, began this week and will continue until August 1st.

A vital closure for a threatened species

The U.S. Forest Service confirmed the presence of a nesting pair on the Main Cliff, a location drawing climbers from around the world. While Rumney Rocks is known for its internationally recognized climbing routes and often-crowded parking lots, the falcons’ territorial behavior necessitates the closure. According to officials, these birds, among the fastest on Earth—capable of dives exceeding 240 mph—can become aggressive when defending their nests. The Forest Service stated, “They can also be very territorial during this time period and may even attack climbers who get too close to their nest,” emphasizing the need for this protective measure.

This isn't the first time Rumney Rocks has seen partial closures due to peregrine falcons. In 2022, a similar nesting pair successfully raised three chicks on the Main Cliff, demonstrating the area’s suitability for the species. The current situation underscores the precarious status of peregrine falcons in New Hampshire; harassing or killing one is illegal.

New Hampshire Audubon’s recent data reveals a significant increase in the peregrine falcon population. The 2025 breeding season saw a record-high 37 territorial pairs documented—a remarkable 30% increase compared to the previous year. The sheer number of nesting pairs suggests a resurgence of the species, but also highlights the ongoing need for conservation efforts and responsible recreational practices.
