High above Yosemite Valley, peregrine falcons soar against granite backdrops, dive at scorching speeds and nest on towering cliffs. Just a few decades ago, these fast-flying raptors neared extinction; thanks to nationwide recovery efforts and DDT bans, they have rebounded.

In Yosemite, Conservancy donors have played a key role in funding the park’s efforts to save peregrines. Meanwhile, on the walls, rock-climbers have witnessed the raptors’ comeback while collaborating with wildlife experts to ensure the success of falcon broods.

Today, your support can help the park’s falcon population continue to flourish, through a project focused on ensuring climbers share the cliffs safely with peregrines, which remain a special-status species in California.

Through this grant, biologists will use surveys of peregrine breeding sites to implement targeted, temporary closures of climbing routes near nesting areas. This data-driven process balances recreation and wildlife management by protecting fledgling falcons while maximizing climbers’ access to the walls. Researchers will also develop falcon-management plans to share with other parks and climbing areas.

Your support will help scientists and climbers work together to protect an iconic bird of prey.

Project Notes

The peregrine falcon recovery project is a success story about protecting the world's fastest animal on some of the world's most dramatic cliffs.
