Zürich Zoological Garden, privately owned zoological park partially funded by the city and canton of Zürich. Opened in 1929, the 10-hectare (25-acre) zoo exhibits nearly 2,100 specimens of more than 380 species. It is home to many ungulates and a breeding group of Humboldt penguins. Its specialties include vicuñas, pygmy hogs, snow leopards, Arabian oryx, and Rothschild’s mynah birds. The zoo serves as the repository for the vicuña studbook.
