Zoo

A zoological garden or zoo is a place where animals are restricted within artificial environments and exhibited to the public.

The first zoos were private menageries, usually belonging to monarchs. King Charles I of England established a zoo with a large python as the main attraction. The first public zoo was established in Vienna in 1752, when the Habsburg emperors decided to grant public access to the former privately-owned Schönbrunn Palace menagerie, now called Tiergarten Schönbrunn Zoo Vienna. After the French Revolution, the Paris Zoo was opened to the public.

Over time, the mission of zoos has shifted from simply displaying animals for the wonderment of the public, to scientific study, and, later, to breeding them, and in particular maintaining populations of animals that are endangered or even extinct in the wild. The first scientific zoological garden in the modern world was founded in London in 1828 by the Zoological Society of London. It was opened to the public in the same year, as a way of funding its scientific work. Londoners soon shortened "zoological gardens" to "zoo." It was the Zoological Society of London, too, which was to be the first to create an open wild animal park, with the establishment of the Whipsnade Wild Animal Park on the Chiltern Hills in 1926. The famous naturalist Charles Darwin enjoyed visiting the London Zoo in order to observe the behaviour of its animals. The first live gorilla to be exhibited there created quite a sensation and reportedly influenced some of Darwin's thinking on evolution and on emotions and intelligence in non-human primates.

Some highly developed zoos harbor research groups, which have extremely valuable initiatives in the preservation of endangered species, in the study and reproduction of rare animals (such as white tigers), in the discovery of new techniques for maintaining animals in captivity and feeding them, in veterinary medicine of exotic species, and so on.

Most modern zoos keep animals in enclosures that attempt to replicate their natural habitats. Many zoos now have special buildings for nocturnal animals, with dim red lighting during the day, so the animals will be active when visitors are there, and bright lights at night to ensure that they sleep. Special climate conditions are created for animals living in radical environments, such as penguins. Special enclosures for birds, insects, fishes and other aquatic life forms have also been developed and are used in many zoos.

A petting zoo (also called children's farms or children's zoos) features a combination of domestic animals and some wild species that are docile enough to touch and feed. Petting zoos are extremely popular with small children. In order to ensure the animals' health, the food is supplied by the zoo, either from vending machines or a kiosk nearby. In addition to independent petting zoos, many general zoos contain one within it.

Sometimes monkeys are not separated from the public, e.g. in the Apenheul Zoo in Apeldoorn. Peafowl are also frequently allowed to roam free in zoos.

Most large cities in the world have zoos, though of drastically varying size and quality. Modern zoos are very dynamic, and are always breeding animals, promoting conservation, and building new exhibits. Major zoos are important tourist attractions, sufficiently so that governments may underwrite or subsidize the zoo's operating expenses. Public funding of zoos is also justified by their educational value, and they are a common destination for school field trips. Even so, many zoos have signs that provide little more information than an animal’s species, diet, and natural range. Most zoo funding primarily comes from donations and entrance fees.

Zoos vary in size and quality—from drive-through parks to small roadside menageries with concrete slabs and iron bars. Birds’ wings may be clipped so that they cannot fly, and many animals who live in large herds or family groups in nature are kept alone or in small groups. Natural hunting and mating behaviors are virtually eliminated by regulated feeding and breeding regimens.

More than 135 million people visit zoos in the United States and Canada every year, but most zoos operate at a loss and must find ways to cut costs or add gimmicks that will attract visitors. The Wall Street Journal reported that “nearly half of the country’s zoos are facing cutbacks this year … [a]ttendance, meanwhile, is down about 3% nationwide.”
