Zoo exhibits where visitors enter enclosures of non-aggressive species, such as lemurs, marmosets, birds, lizards, and turtles. Visitors are asked to keep to paths and avoid showing or eating foods that the animals might snatch. Some zoos keep animals in larger, outdoor enclosures, confining them with moats and fences, rather than in cages. Safari parks, also known as zoo parks and lion farms, allow visitors to drive through them and come in close proximity to the animals. Sometimes, visitors are able to feed animals through the car windows. The first safari park was Whipsnade Park in Bedfordshire, England, opened by the
Whipsnade Zoo mother and hand-reared by keepers. Wild Wild Whipsnade was opened in 2010. This exhibit is home to several species of animal that lived in the wild in Britain hundreds of years ago. These include Eurasian brown bears, wolverines, Eurasian lynx, reindeer, wild boar, and European bison. Other species in the zoo's collection that are not part of a themed exhibit include Amur tigers, blesbok, Thomson's gazelle, Oriental small-clawed otters, red pandas, gemsbok, sloth bears, meerkats, Impalas, ostriches, reticulated giraffes, southern white rhinoceros, onager, Przewalski's wild horses, common chimpanzees, egrets, Caribbean flamingos, rockhopper penguins, Grévy's zebra, bongo, roan antelope, common hippopotamus,
