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 Kaylee's female calf Donna, and Azizah's male calf Sam. Their paddock is seven acres, and features three pools, mud wallows and dust baths. One of the female elephants, named Karishma, and her pregnancy with her first calf George, featured heavily in the first series of the ITV documentary programme "The Zoo", which follows the daily lives of the staff at both Whipsnade and London Zoo. Another female calf was born during the Queens birthday celebrations and was aptly named Elizabeth. The elephant herd has a brand new indoor facility, the Centre for Elephant Care, which opened in Easter of 2017.
