giant anteaters, De Brazza's monkeys, cotton-top tamarins, pygmy hippos and various birds and reptiles. This exhibit was included in the zoo's 1973 master plan, and was originally intended to house only African tropical species; however, more South American and Asian animals began being displayed in the Tropical Forest by the late 1990s. One gorilla named Little Joe escaped his enclosure several times in 2003. He was later separated from the gorilla family, but later returned in 2007. Also in 2007, the zoo's gorilla exhibit was reopened after extensive renovations. As of 2011, a male giant anteater named Jockamo resides in the former warthog enclosure. In spring 2020, a wildlife trade exhibit showcasing artifacts will be displayed in the tropical forest public areas. Serengeti Crossing (known as Bongo Congo from 1997 to c. 2003): A grasslands exhibit with common ostriches, white-bearded wildebeest, Hartmann's mountain zebras, and common warthogs. The exhibit first opened in 1997, making it one of the first new exhibits to open at the zoo since the opening of the African Tropical Forest in 1989. Reconfigured to 1.25 acres in 2018, adding a new path and entry garden. The observation decks that once overlooked this exhibit have been collected. The area also has Cape porcupines and wattled cranes. Kalahari Kingdom: A large African themed area housing two African lion brothers. Visitors can view them through a replica of a land rover "crashed" into the exhibit, glass, or from over a moat. The opening of this exhibit in 1997 marked the first time lions had been exhibited at the zoo since the old Lion House was closed in the early 1970s. Other animals included are red river hogs, kori bustards and African spurred tortoises. Tiger Tales: This exhibit opened in 2006 and marked the first time the zoo housed tigers for 30 years. Currently, the zoo has a 17-year old tigress named Anala. She and a white tiger named Luther (who passed on in 2019 from cancer) were confiscated as cubs by U.S. Fish and Wildlife Service agents from a wildlife sanctuary trying to sell them. Outback Trail: Australian animals such as red kangaroos, emus, citron-crested cockatoos, North Island brown kiwis, laughing kookaburras and tawny frogmouths. This exhibit opened around 1998, the same year the Butterfly Landing exhibit first opened. A seasonal budgerigar aviary offers opportunities to feed them. Giraffe Savannah: Opened in 1999, this large habitat contains a herd
