Birds of prey, including owls, hawks, falcons, and other raptors, face many of the same threats as other Sierra Nevada birds, including habitat loss, climate change, pollution, and changing fire patterns that can greatly alter habitat. However, several of the region’s birds of prey may be particularly vulnerable due to their high position on the food web, need for large expanses of habitat, and reliance on characteristics of old forests – like large trees and closed canopies – that can take decades or centuries to develop fully after disturbance.

IBP scientists collaborate with federal, state, and private land managers to study and conserve Sierra Nevada populations of birds of prey, including Spotted Owl, Great Gray Owl, and American Goshawk. Our work advances the understanding of the ecology, conservation status, and habitat needs of these species, particularly in relation to forest management, climate change, and the effects of fire. We use our own findings, as well those of other scientists, to develop practical, science-based strategies land managers can implement to conserve the birds.
