LOWELL, Mass. (AP) — State wildlife officials plan to fit a pair of peregrine falcon chicks with ID bands so they can track the birds, which have been making a comeback.

Experts with the state Division of Fisheries and Wildlife say they'll band the chicks on Monday morning.

They're among more than 25 born on rooftops at the University of Massachusetts-Lowell over the past decade. The IDs will let biologists track the chicks as they leave the nest and mature.

Peregrine falcons are a threatened species, but they've been rebounding in recent years.

The chicks hatched two weeks ago in a nest box on the roof of UMass-Lowell's 18-story Fox Hall— the tallest building in Lowell.

They're expected to fly away early in July. A webcam is tracking them live in the meantime.
