Comments:     BBC -Great Meadows National Wildlife Refuge, Concord  – Leader: Kathy Stark Dia.  Lovely bright evening of blue skies with white and later pink scattered clouds. A strong breeze kept passerines quiet early in the walk but the wind calmed by the time we got to the boat launch where there was a good bit of activity.
