ACADIA NATIONAL PARK, Maine (AP) — Acadia National Park officials are closing several popular hiking trails to protect peregrine falcons that have been showing pre-nesting courtship behavior.

The closure of the popular Precipice Trail and other trails near the park’s Precipice and Valley Cove cliffs is expected to last until early August. That’s about five weeks after any newborn peregrine chicks would be expected to take their first flights.
