Canceled: Pop-Up Audubon I

Please note that Pop-Up Audubon II is canceled on Sunday, September 27. Thank you for your understanding and we apologize for the inconvenience. Celebrate Autumn in Prospect Park by supporting migratory birds! Join Prospect Park Alliance Naturalists to design your own colorful autumn leaf window cling. These fun, decorative clings help prevent bird-window collisions by making glass more visible to migrating birds. All materials provided — family-friendly and free to participate! Also enjoy: Stay + Play, 12–3 pm: Families, children and caregivers can enjoy a range of nature fun including games, puzzles and drawing activities. Nature on the Go, 3–4 pm: Join an Alliance Naturalist as we explore the park's trails for signs of fall. Be a Park Champion by helping pick up trash along the way. Pop-Up Audubon will be canceled in the event of inclement weather, including rain, extreme heat (temperatures of 90°F or higher), or “Very Unhealthy” air quality conditions.
