In November, the brisk air fills with migrating birds just as acorns adorn native oak trees. Learn about the distinctly somber song of the golden-crowned sparrow and how to correctly identify the different species of oaks found in Midpen preserves. Learn more about Midpen's trail building process and how we are working to be the best neighbor we can (eat your heart out Ned Flanders). Plus, join us for a special open house showcasing several restoration-focused projects!
