Caldwell Zoo, Wildlife conservation center in Tyler, United States

Caldwell Zoo is an 85-acre (34 ha) zoological park in Tyler, Texas, accredited by the Association of Zoos and Aquariums and a member of the World Association of Zoos and Aquariums. Its grounds include a 15-acre native Texas area opened in 1983, reptile and aquarium sections opened in 1984, and African exhibits rebuilt in 1987 with large pastures and an overlook.

The zoo grew out of the Child Development Laboratory, started in 1937 by the Hogg Foundation and the American Association of University Women of Tyler, and run by David King Caldwell and his wife, who brought in animals for children. It opened on its current site in 1953. A 1970 break-in that killed several animals led local children to raise money, enough to buy an African elephant and begin modernizing the zoo. The city added 40 acres in 1976, and a 15-acre native Texas area opened in 1983.

The zoo began as the Child Development Laboratory, run by David King Caldwell and his wife, who brought in animals for children. Today it keeps more than 400 parakeets and cockatiels in the Wild Bird Walkabout, and bird, otter and penguin presentations are used to teach the public about wildlife.

The zoo sits on 85 acres (34 ha) in Tyler, with the 15-acre (6.1 ha) native Texas area opened in 1983 among its sections. The grounds are laid out along walking paths between the African pastures, reptile and aquarium buildings, and the bird walkabout. Allow several hours to cover the full circuit on foot.

The zoo's breeding work includes reticulated giraffes, flamingos, black rhinoceroses, jaguars and giant anteaters, and it took part in the first cheetah born through artificial insemination. In January 2014 a litter of four lion cubs arrived, the first at the zoo in 20 years.
