Zoo Atlanta was founded in 1889, when businessman George V. Gress purchased a bankrupt traveling circus and donated the animals to the city of Atlanta. City leaders opted to house the collection in Grant Park, which remains the zoo's present location. Original residents of the zoo included a black bear, a raccoon, a jaguar, a hyena, a gazelle, a Mexican hog, lionesses, monkeys, and camels. The zoo's collection expanded in the 1930s with the personal donation of a private menagerie owned by Asa G. Candler, Jr.
The 1950s and 1960s were decades of renovation and construction at the zoo, but by the early 1970s, many of its exhibits and facilities were outdated and showing signs of disrepair. In 1970, a small group of concerned citizens founded the Atlanta Zoological Society in hopes of raising funds and awareness for the institution.
Following a period of decline in the mid-1980s, the zoo was privatized in 1985 with the creation of a nonprofit organization, Atlanta Fulton-County Zoo Inc., and was renamed Zoo Atlanta that same year. A 20-year period of aggressive restoration followed, marked by several high-profile exhibit openings, including The Ford African Rain Forest, in the late 1980s and early 1990s. A pair of giant pandas, Lun Lun and Yang Yang, made their debut at Zoo Atlanta in 1999.
Zoo Atlanta also remains home to offspring of its best-known gorilla, Willie B. (ca. 1959-2000). The zoo is also home to six of Willie B.'s grandchildren: Macy B (2005) and Merry Leigh (2011) and Mijadala (2016), born to Kudzoo; Gunther (2006) and Anaka (2013), born to Sukari; Andi (2013), born to Lulu.
The Living Treehouse is an extension of The Ford African Rain Forest completed in 2004. The exhibit houses an aviary of African birds, as well as black-and-white ruffed lemurs and ring-tailed lemurs, with adjacent habitats for Angolan colobus monkeys, drills, Schmidt's guenons, and Wolf's guenons. In 2017, Zoo Atlanta introduced two crowned lemurs.
Opened in 2010, Trader's Alley: Wildlife's Fading Footprints is focused on species impacted by the international wildlife trade. The exhibit introduced Malayan sun bears and raccoon dogs to the collection. Opened in 2011, an adjacent series of exhibits, Complex Carnivores, introduced bush dogs, binturong, and fossa.
Zoo Atlanta’s African Plains, opened in 1989, houses wildlife native to the grasslands and desert of Africa, including lions, African elephants, southern ground hornbills, kori bustards, meerkats, and warthogs. African forest species include yellow-backed duikers and eastern bongos. A multi-species savanna landscape was home to giraffes, zebras, black rhinos, ostrich, and lesser kudu. Also featured is a naked mole rat colony housed in its own building for easy viewing. A giraffe feeding experience opened in 2012.
Zoo Atlanta is one of four institutions in the U.S. that house giant pandas. Lun Lun (female) and Yang Yang (male) arrived in Atlanta as juveniles in 1999 and reside at the zoo on loan from China. The pair's first cub, male Mei Lan, was born on September 6, 2006. A second cub, male Xi Lan, was born August 30, 2008. Female Po was born November 3, 2010. Po's name was announced by actor Jack Black in 2011; Po was named after Black's character in the DreamWorks films Kung Fu Panda. A fourth and a fifth cub, both female, born July 15, 2013, were the first twin pandas to be born in the U.S. since 1987. Their names were announced on ABC's Good Morning America on October 23, 2013; 100 days after their birth, which is a Chinese tradition. The names are Mei Lun and Mei Huan. As of October 2015, Mei Lan, Xi Lan, Po, Mei Lun, and Mei Huan reside at the Chengdu Research Base of Giant Panda Breeding in China.
A sixth and seventh cub, both female, were born September 3, 2016. Their names were announced on their 100th day of life: Ya Lun and Xi Lun. Like their older siblings, the twins will return to China once they are fully grown and weaned, likely between 3-5 years of age.
The Orangutan Learning Tree Project, launched at Zoo Atlanta in 2007, utilizes in-habitat touch screen technology to allow orangutans to engage in computer puzzles, games and problem-solving exercises while guests observe their activities on a linked monitor.
The Zoo Atlanta herpetology department manages more than 450 reptiles and amphibians representing over 100 species, though because of the size of the World of Reptiles exhibit building, not all of these animals can currently be displayed. The zoo is the only zoological institution to successfully breed Arakan forest turtles, a critically endangered species harvested nearly to extinction for food and traditional medicine. A rare Guatemalan beaded lizard hatched at Zoo Atlanta in March 2012.
The World of Reptiles was the zoo's oldest public building used for public exhibits, designed in the late 1950s and opened to the public in 1962. The building was home to hundreds of snakes, lizards, turtles, tortoises, frogs, toads, and salamanders from around the world. Exhibited species included black mamba, king cobra, indian star tortoise, Spider tortoise, Alligator snapping turtle, American alligator, and reticulated python. Georgia native species include eastern diamond-backed rattlesnake, timber rattlesnake, copperhead, water moccasin, Carolina pygmy rattlesnake, bog turtle, and gopher tortoise.
In 2009, the Association of Zoos and Aquariums noted that "the facility is a major concern primarily because of age." The World of Reptiles once housed critically endangered gharial (a species of crocodile from India), but because the aging facility could not maintain adequate heat, they were sent to other zoos.
Construction began in 2013 on Scaly Slimy Spectacular: The Amphibian and Reptile Experience, replaced the World of Reptiles. The exhibit opened in 2015.
Zoo Atlanta's Outback Station houses Australian wildlife, including red kangaroos, Major Mitchell's cockatoos, kookaburra and a double-watted cassowary. The petting zoo is home to Saanen goats, Oberhasli goats, Boer goats, Southdown babydoll sheep, Gulf Coast sheep, Nigerian dwarf goats, and two kunekune pigs.
Zoo Atlanta is a participant in the AZA Species Survival Plan for the following programs:
Zoo Atlanta also participates in several international conservation initiatives, among them the Asian Turtle Crisis and Global Amphibian Decline. Staff members from Zoo Atlanta and the Atlanta Botanical Garden have established captive assurance colonies of Panamanian frogs threatened by the spread of chytrid fungus. (Chytrid is the cause of the infectious amphibian disease chytridiomycosis.)
