Suitable breeding, foraging, and resting habitats in the Sierra Nevada include gray pine ( Pinus sabiniana)-oak woodland, chaparral, Pacific ponderosa pine ( P.
However, suitable habitat (intermediate density or use) is available there. Īccording to Verner and Boss, optimal habitat for peregrine falcons (based on high breeding density or use of a defined area) is not available in the Sierra Nevada. Dominant species include California sagebrush ( Artemisia californica), Eastern Mojave buckwheat ( Eriogonum fasciculatum), black sage ( Salvia mellifera), and snakeweed ( Gutierrezia spp.). East of San Francisco Bay, peregrine falcons occupy cliffs and rocky areas in coastal sage scrub habitat on southwest-facing slopes. versicolor) on exposed, oceanside sites and coyote bush ( Baccharis pilularis) on less exposed sites. sparsifolium) chaparral, and mixed-chaparral communities.Ĭoastal sage scrub is vegetated with bush lupine ( Lupinus spp.) and manycolored lupine ( L.

Peregrine falcons are rarely seen in the shrub-steppe in southeastern Washington. In Washington and Oregon, peregrine falcons occupy cliffs in relatively open habitats ranging from low-elevation grasslands to high-elevation pine ( Pinus spp.) forests in all seral stages ( cited in ). contorta), California wax-myrtle ( Myrica californica), and European beachgrass ( Ammophila arenaria), particularly in winter. sitchensis), shore pine ( Pinus contorta var. In western Washington, peregrine falcons hunt birds along beaches, low dunes, and surrounding areas with Sitka spruce ( P. Drier areas with similar vegetation are also commonly (Ericacea) with many small lakes and sedge-grass (Cyperacea-Poacea) marshes. In Alaskan tundra, peregrine falcons hunt in wet tussock-heath Populus tremuloides) forests with prickly rose ( Rosa acicularis) characterize cliff brinks on the Yukon River.

Arctic peregrine falcons are found in the Provides a distributional map of the peregrine falcon in North and South America.Īll 3 North American subspecies occur in Alaska. Peregrine falcons were reintroduced in many urban areas during recovery efforts by the US Fish and Wildlife Service and other organizations. Globally, peregrine falcons breed up to 75 ºN latitude. In North America, the peregrine falcon's range extends from western Alaska to southern Greenland and south into Mexico (, review by Mountainous regions, continental forests, maritime islands, and urban areas (review by ). Types in which peregrine falcon occurs include arctic tundra, tropical ecosystems, deserts, wetlands, grasslands, The peregrine falcon is global in distribution.
