Peter U led a very technical trip on the Nashua River today. Diana and Paul from the Brookline Birders came along and helped identify birds. It's amazing how they can spot and identify birds (sometimes by their call only).Only one "swimming" episode. And one tree followed us into a snag making extricating the group a bit of a challenge for Pete! Birds - great blue heron, red start, spotted sandpiper, cedar waxwings, king fisher, king bird, and I'm sure Paul and Diana can add lots more to that list. Thanks everyone!
