Two popular trails at Acadia National Park have reopened after being closed to protect nesting peregrine falcons. Park officials said sections of the Flying Mountain and Jordan trails at Valley Cove and Jordan cliffs reopened Wednesday. The trails closed in April and May and had been expected to reopen in August, but they opened early after the falcons failed in their nesting attempts. The popular Precipice Trail remains closed to protect nesting activities on that trail. The peregrine falcon is listed as a Maine endangered species.
