Their range is pretty much the entire Western US, with a tiny bit of Canada and Mexico at the far north and south. They thrive in areas that have both cliffs (for nesting) AND plains (for hunting ground squirrels); we've got those conditions in spades in this part of the world. They're studied extensively at the The Morley Nelson Snake River Birds of Prey National Conservation Area in Southwest Idaho.
