Why do we have so  many acorns one year, and very few other times? How are the native wildlife preparing for the winter, and what can we see at this time of year? What is the science behind the leaves changing colors?  What are the true hibernating mammals?  Join Patti Steinman, Mass Audubon Education Coordinator to explore these questions as well as others. This leisurely walk will take place on the Wistariahurst grounds, or indoors if inclement weather.
