The Sacramento Zoo is a zoo located in William Land Park in Sacramento, California. It opened on June 2, 1927, with 40 animals. At that time, it occupied 4.2 acres (1.7 ha), which remained the case until the early 1960s when the zoo expanded to its current 14.3 acres (5.8 ha). As of December 2012, the zoo had just over 500 animals on site.
