Adults are invited to join Broad meadow Brook Wildlife Sanctuary Feb. 23, from 9 a.m. to 5 p.m., for a trip to the coast of Rhode Island to explore Sachuest Point National Wildlife Refuge for harlequin ducks, eiders, surf scoters, and scaup bobbing in choppy, cold waters. Turn your lenses to shore and spy on purple sandpipers crawling over the exposed rocks. Be prepared for bitterly cold winds, and bring lunch, binoculars, and a field guide. Dress in layers for the cold weather. For more information and to register, call 508-753-6087. Fee: $30 Mass Audubon adult members, $37 adult non-members.
