A baby vulture was born at the zoo in June 2013 but was abandoned by its parents and had to be hand-reared and reintroduced gradually.

It became famous for its apes, including a gorilla named Bushman, until the Great Ape House opened. The Primate House's interior was heavily renovated in the early 1990s and it was re-opened as the Helen Brach Primate House in 1992 with eight diorama-style naturalistic exhibits simulating the swamps and rainforests of the animals' natural habitats in the wild. Perhaps its most notable residents are a family of white-cheeked gibbons that have a spacious room inside as well as an outdoor habitat for playing in the warm winter months. The zoo's male and female gibbons gave birth to baby Daxin on August 16, 2013. Crowned lemurs joined the exhibit in October 2013 from the Indianapolis Zoo and a baby lemur was born at the zoo on April 14, 2014.

It has been redesigned multiple times, most recently in 1991, and is currently home to multiple habitats recreating the tropics, savanna, sea shore, desert, wetlands, and other biomes, with a tropical free-flight aviary allowing guests to become immersed with perching and aquatic birds without fences or glass. Some of the zoo's most notable birds include the famous laughing kookaburra in the scrub display, multiple scarlet ibis specimens in its swamp display and the Bali myna, a critically endangered bird that Lincoln Park Zoo breeds, while also maintaining the species' studbook. Thirty-one mynahs have been born at the zoo since 1972, with the most recent set of chicks being born in mid-2012.
