Four fledgling peregrine falcons in Boston were tagged Wednesday, May 24th by researchers hoping to track the young birds after they leave the nest. The chicks, known as eyeases, were born on May 11 to one of only 30 pairs of nesting peregrine falcons in Massachusetts. Their rooftop nest is located at 177 Huntington Avenue, near the Prudential Center.

Small silver tags were placed on the eyeases left feet by members of Mass Audubon and the Mass Department of Fisheries and Wildlife. Green and black tags were secured to the right feet.
