The Cincinnati Zoo and Botanical Garden is one of the oldest zoo in the United States and is located in Cincinnati, Ohio. It opened in 1875, just 14 months after the Philadelphia Zoo on July 1, 1874. The Reptile House is the oldest zoo building in the United States, dating from 1875.
The Cincinnati Zoo is located in the Cincinnati neighborhood of Avondale. It was founded on 65.4 acres (26.5 ha) in the middle of the city, and since then it has acquired some of the surrounding blocks and several reserves in Cincinnati's outer suburbs. The zoo conducts breeding programs, and was the first to successfully breed California Sea Lions. The zoo also has other breeding programs including Cheetahs, Sumatran rhinoceros, Malayan tigers, Western Lowland Gorillas, Pottos, and Masai giraffes. The Cincinnati Zoo was the home of Martha, the last living passenger pigeon, which died there in 1914. It was also home to the last living Carolina parakeet in 1918.The zoo is an accredited member of the Association of Zoos and Aquariums (AZA), and a member of the World Association of Zoos and Aquariums (WAZA).
Animals and exhibits:
Animals at the zoo have held several records, including the longest living alligator in captivity at the time (at about 70 years of age), the fastest cheetah in captivity,and the largest Komodo dragon (who died in 2005). The zoo was the first in the United States to put an aye-aye on display, and after losing its last aye-aye in 1993, it finally acquired another in 2011: a 6-year old transferred from the Duke Lemur Center in North Carolina. The zoo is one of only a dozen in North America to house and breed bonobos (also known as pygmy chimpanzees), an endangered species of the great apes.
Center for Conservation and Research of Endangered Wildlife (CREW):
The Cincinnati zoo has been active in breeding animals to help save species, starting as early as 1880 with the first hatching of a Trumpeter Swan in a zoo, as well as four passenger pigeons. This was followed in 1882 with the first American bison born in captivity.
In 1981 the zoo established the Carl H. Lindner Jr. Family Center for Conservation and Research of Endangered Wildlife for the purpose of using science and technology to understand, preserve, and propagate endangered flora and fauna and facilitate the conservation of global biodiversity. In its Frozen Zoo plays a major role. In it are stored over 2,500 specimens representing approximately 60 animal and 65 plant species.
Once the Night Hunters building transformation was complete, the Nocturnal House Closed. The Night Hunters exhibit is phase one of a larger outdoor Cat Canyon expansion which is scheduled to open by May 2012. The expanded Cat Canyon will link the Night Hunters experience with the current Tiger Canyon exhibits and include new space for Malayan tigers, Pumas and Snow Leopards. The Cat Canyon expansion is set to start on September 6, following Labor Day Weekend, and be finished in early summer 2012.
