"Two hundred thirty. That’s how many different bird species have been identified at Fresh Pond Reservation since 1984. This whopping number includes 11 species listed as endangered, threatened, or of special concern by the Massachusetts Division of Fisheries and Wildlife.
It also includes the 13 different species of ducks (including ring-necked, ruddy, and canvasback) and 35 different species that nest at the lake in the spring. This kettle lake—formed in a depression left by a glacier—anchors the North Cambridge area and offers many opportunities for running, walking, biking, golf, and, not surprisingly, bird-watching. As a result of the diversity of people that Fresh Pond attracts, you’ll catch plenty of different languages as you walk."
