Families are invited to join us for a night of owls at Upper Main Line YMCA! Elmwood Park Zoo will present their live owl and raptor show in the gymnasium. Our staff naturalists will demonstrate owl pellet dissections and then lead a night owl prowl from our Nature Center throughout the YMCA's Cassatt Preserve in search of some of our local owls. Dress for the outdoors and bring a flashlight! FREE event to the community.
