Swing over to Brookfield Zoo’s Tropic World for Ape Awareness Weekend. Learn about the apes of Asia and Africa and discover ways to help wild ape populations. The event, which takes place Saturday, April 9, from 10:00 a.m. to 5:00 p.m., and Sunday, April 10, from 10:00 a.m. to 3:00 p.m., will highlight the zoo’s three ape species: white-cheeked gibbons, orangutans, and western lowland gorillas. Throughout the weekend, animal care specialists will present informal Zoo Chats about the zoo’s apes. Zoogoers can also participate in ape-related activities, including comparing their own weight and handprints with those of an orangutan and gorilla, learning what the apes’ diets are at Brookfield Zoo, and even building a gorillas’ nest.
