Acadia National Park has reopened two of three hiking trails closed since April to protect peregrine falcons as they nest. The Precipice Trail and Orange & Black Path were reopened Friday, but the Jordan Cliffs Trail remains closed. Park officials closed those areas April 13 to protect the falcons from inadvertent disturbance or harassment. The protection of nesting areas allowed the hatching or fledging of eight falcon chicks this year, compared to at least five last year and 11 in 2016.
