Merryspring Nature Center in Camden will host its annual Family Winter Ecology Festival on Saturday, Feb. 13 from 10 a.m. to noon.

There will be indoor and outdoor activities for people of all ages. Wildlife rehabilitator Barbara Tomlinson of Wild Haven will introduce live birds of prey — a barred owl, red-shouldered hawk and turkey vulture — at her presentations at 10 a.m., 10:45 a.m. and 11 a.m. She will show her extensive display of animal pelts and skulls.

Forester Didier Bonner-Ganter will lead a walk on winter tree identification and fun tree facts at 10:15 a.m. and 11:15 a.m. Maine Guide Mark DiGirolamo will lead walks on winter bird life and animal signs at 10:30 a.m. and 11:30 a.m. Children can make their own pinecone birdfeeders. If the clouds part, Wayne Barber and Lys McLaughlin Pike of the Central Maine Astronomical Society will let attendees safely view the nearest star, the sun, through their solar scopes. Greg Dorr will demonstrate winter camping techniques, and if the snow is right, Paul Cartwright will demonstrate how to build an igloo.

The free event is a great time to walk (or perhaps snowshoe) the beautiful trails at Merryspring and tap into the knowledge of these naturalists. There will be cookies and hot cider available in the Nature Center.

Merryspring is located at the end of Conway Road just off Route 1 by the Hannaford shopping plaza in Camden. For more information call Merryspring at 236-2239 or visit merryspring.org.
