Four peregrine falcons have hatched on the roof of an office building at 177 Huntington Avenue in Boston. The chicks, known as eyases were born to a pair of nesting falcons on the roof of the 25-story office tower overlooking the Back Bay and South End. The pair calls 177 Huntington home as a result of a partnership with the Massachusetts Audubon Society, and is one of approximately 30 nesting peregrine falcon pairs located throughout Massachusetts.
