This Columbus Day, learn about the creatures who roam the night. Meet nocturnal animals such as a barred owl from the Seneca Park Zoo. Take pictures with storybook characters that love nighttime, including Janell Cannon’s bat Stellaluna and Jan Brett’s hedgehog Hedgie. Visit the echolocation station to find out how bats use sound waves to find their way in the dark. Create a bat hat or paper plate hedgehog to take home. And be delighted by a performance of Winnie the Pooh: The Musical presented at 2 p.m. by the Rochester Association of Performing Arts.
