If you’ve ever found a skull or bone while walking in the woods and wondered just what it may have come from, the upcoming workshop at Felix Neck Wildlife Sanctuary can shed some light. Using the Field Guide to Skulls and Bones of Mammals of the Northeastern United States, the interactive workshop will teach you what to look for when identifying bones. You can even bring in any bones you may have lying around the house and get some help identifying them.

The workshop is from 1 to 4 p.m. on Saturday, Feb. 22, and cost is $25 for members and $30 for nonmembers. For more information, call 508-627-4850 or register on line at massaudubon.org/felixneck.
