If you walk near woods or trees, the mammals you are most likely to see are squirrels. They are fun to watch as they run and jump and play, flick their bushy tails, chase each other up trees, bury acorns in the fall and dig them up again to eat in winter. But in spite of the playfulness that makes squirrels fun to watch, they face the same challenges in their lives as any other kind of wildlife. Learn more about these lively little mammals as we celebrate their lives with activities and crafts.
