The Cambridge Water Department has made and put up on the Reservation four nesting boxes for Tree Swallows. Two (including this one) are in the Lusitania wetland, one in the Butterfly Meadow, and one inside the Fresh Pond fence near Little Fresh Pond. The Friends group will also be putting up Swallow boxes. When they are all in place they will be numbered, and birders will be asked to report sightings to the Ranger or the Friends group.
