The Orange County Zoo is a small 8acre zoo located within the 477acre Irvine Regional Park in the city of Orange, California, United States. The zoo is mainly home to animals and plants that are native to the Southwestern United States.HistoryThe current zoo is owned, staffed and operated by the County of Orange, and officially opened as the Irvine Park Zoo in 1985.However, there have been animals in captivity on the site since 1905, when red foxes were introduced and bred by J.A. Turner. In 1920, a small collection of animals featuring a pair of mule deer was started by Tustin rancher Sam Nau. Eventually Nau built a pen for the deer. The main attraction was an alligator exhibit until a bird exhibit including cockatoos, quail, doves, and parakeets was added in 1935.
