Only four out of seventeen boxes at Charles River Peninsula are still active. Two bluebird nests (one with eggs, the other with chicks) and two tree swallow nests (both ready to go). I spent an afternoon last week cleaning out the finished boxes. Will go back and clean out the rest when the bluebirds have left.
Tree Swallow fledgling
I will miss the parental dive-bombing when these guys finally fledge. Perhaps the red-winged blackbirds can take up the slack.
