 During the summer, preschool children spent two mornings a week at the Maine Audubon Summer Squash Program at Gilson Farm in Falmouth. They explored the woods, pond and meadows, and learned about nature through stories, games, and crafts. On the camp's closing day, they learned why butterfly wings have colorful patterns, and they showed off their costumes to their parents while demonstrating the ways butterflies protect themselves from birds.
