The Cincinnati Zoo & Botanical Garden opened its doors in 1875, making it the second oldest zoo in the United States. It began with a small collection of animals, including a pair of bison and a few birds. Over the years, the zoo has grown significantly, both in size and in its commitment to conservation and education.
In the 20th century, the zoo became a leader in breeding endangered species, including the first successful birth of a California condor in captivity. The zoo's dedication to conservation is evident in its many programs and partnerships aimed at preserving wildlife and their habitats. Today, the Cincinnati Zoo is not only a beloved local attraction but also a respected institution in the global conservation community.
