Rocky Mountain in March: what the park service says

March 15 ends Rocky Mountain's winter bald eagle closure along the Colorado River on the west side. Spring then brings temporary closures around nesting golden eagles, hawks and peregrine and prairie falcons, which the park monitors through the breeding season and may lift early where no nesting is seen. Report a nest site or aggressive dive-bombing to romo_information@nps.gov.
