A 'zoological garden', 'zoological park', or 'zoo' is a facility in which animals are confined within enclosures and displayed to the public, and in which they may also be bred. The term zoological garden refers to the
biological discipline zoology, which derives from
Greek
''Ζωο''("animal"), and ''λογος'' ("study"). The term was first used in 1828 for the ''
London Zoological Gardens'', soon abbreviated to "zoo."
History
The predecessor of the zoological garden is the
menagerie that has a long history from the
Middle Ages to modern times. The oldest existing zoo, the
Vienna Zoo in
Austria, evolved from such an aristocratic menagerie founded in 1753 by the
Habsburg monarchy.
The first public zoo was the ''Ménagerie du
Jardin des Plantes'', founded in
Paris in
1794 primarily for
scientific and
educational reasons. The founders and members of the ''
Zoological Society of London '' adopted the idea of the early Paris zoo when they established
London Zoo in 1828.
The success of London Zoo set off a wave of similar establishments. The first zoological garden established in
Australia was
Melbourne Zoo in 1860. In the same year the first zoo of the
United States opened to the public in
New York City (
Central Park Zoo), although earlier, in 1859, the ''
Philadelphia Zoological Society'' had made an effort to establish a zoological park, but delayed due to the
American Civil War.
When
ecology emerged as a matter of public interest through the 1970s, a few zoos began to consider making conservation their central role, with
Gerald Durrell of the
Jersey Zoo, George Rabb of
Brookfield Zoo, and William Conway of the
Bronx Zoo (
Wildlife Conservation Society) leading the discussion. Since then, zoo professionals became increasingly aware of the need to engage themselves in conservation programmes and the
American Zoo Association soon asserted that conservation had become its highest priority.

Many zoos in Europe and North America keep animals in enclosures that attempt to replicate their natural
habitats, for the benefit of both resident animals and visitors. They may have special buildings for
nocturnal animals, with dim
lighting during the day, so the animals will be active when visitors are there, and brighter 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,
reptiles,
fishes and other aquatic life forms have also been developed.
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 popular with small children. To ensure the animals' health, the food is supplied by the zoo, either from
vending machines or a
kiosk nearby. There are independent and zoo-based petting zoos.
Some zoos have walk-through exhibits where visitors enter enclosures of non-aggressive species, such as
lemurs,
marmosets,
birds,
lizards,
turtles etc. Visitors are asked to keep to paths and avoid showing or eating foods that the animals might snatch. The animals are not tame.
Conservation, education, research
Most modern zoos in Europe and North America display wild animals primarily for the
conservation of endangered
species and for educational and research purposes, and secondarily for the entertainment of visitors.
[5][6]
In 1993, the
World Association of Zoos and Aquariums (WAZA), formerly known as the International Union of the Directors of Zoological Gardens, produced its first conservation strategy. In November 2004, WAZA adopted a new strategy that sets out the aims and mission of zoological gardens of the twenty-first century.
[7]
The breeding of endangered species is coordinated by cooperative breeding programmes containing international studbooks and coordinators, who evaluate the roles of individual animals and institutions from a global or regional perspective. There are regional programmes for the conservation of endangered species:
★ 'America': Species Survival Plans SSP (
American Zoo and Aquarium Association AZA,
Canadian Association of Zoos and Aquariums)
★ 'Europe': European Endangered Species Program EEP (
European Association of Zoos and Aquaria)
★ 'Australasia': Australasian Species Management Program ASMP (
Australasian Regional
★ Association of Zoological Parks and Aquaria ARAZPA)
★ 'Africa': African Preservation Program APP (African Association of Zoological Gardens and Aquaria PAAZAB)
★ 'Japan': Conservation activities of Japanese Association of Zoos and Aquariums JAZA
★ 'South Asia': Conservation activities of South Asian Zoo Association for Regional Cooperation SAZARC
★ 'South East Asia': Conservation activities of South East Asian Zoo Association SEAZA
People for the Ethical Treatment of Animals (PETA) rejects the claim that the purpose of most zoos is to undertake research, to aid in conservation, or to educate. PETA alleges that most zoo research is in fact geared toward finding new ways to breed and keep animals in captivity, so that if zoos ceased to exist so would the need for most of their research. PETA writes that zoos usually favor exotic or popular animals over threatened or endangered local wildlife, in order to draw crowds.
["Zoos: Pitiful Prisons", People for the Ethical Treatment of Animals.]
PETA quotes a curator from the
Smithsonian National Zoological Park in Washington, D.C., who followed 700 visitors over the course of five summers and concluded that "it didn’t matter what was on display ... people [were] treating the exhibits like wallpaper ... officials should stop kidding themselves about the tremendous educational value of showing an animal behind a glass wall."
[8]
Criticism of zoos
Many
animal rights activists disapprove of zoos because they interpret zoos as human domination over equal creatures and criticize their educational value as being superficial and useless.
Some
animal welfare groups however do not fundamentally reject the existence of zoological gardens, but seek to remedy the unnatural and unhealthy conditions in which many captive animals live--particularly the problem of small cages lacking environmental enrichment. Some zoos continue to provide their animals inadequate care, particularly those zoos that are unlicensed, those that are overly commercially-concerned and those that suffer from lack of money.
Stereotypical behavioral patterns such as pacing, rocking and swaying may indicate stress or suffering of animals in unsuitable enclosures. For example, unhealthy
elephants may sway continuously from side to side or rock back and forth.
The majority of the large non-profit and scientifically oriented institutions are working to improve their animal enclosures, although constraints like size and expense make it difficult to create ideal captive environments for some species (for example,
dolphins and other
whales).
[9][10]
Regulation of zoos in the United States
In the United States, any public animal exhibit must be licensed and inspected by the
United States Department of Agriculture.
[11] Zoos may also require special licenses to meet the requirements of their particular locality. For a variety of reasons (such as
zoonotic disease, possession of
controlled drugs for
veterinary use, etc) a zoo in the United States may be inspected and regulated by other agencies including the
Food and Drug Administration,
United States Environmental Protection Agency,
Drug Enforcement Agency,
Occupational Safety and Health Administration, and others.
Depending on the animals they exhibit, the activities of zoos are regulated by laws including the
Endangered Species Act, the
Animal Welfare Act, the
Migratory Bird Treaty Act of 1918 and other laws.
[12]
Additionally, zoos in North America may choose to pursue accreditation by the
Association of Zoos and Aquariums. To achieve accreditation, a Zoo must pass an application and inspection process and meet or exceed the AZA's standards for animal health and welfare, fundraising, zoo staffing, and involvement in global conservation efforts. Inspection is performed by three experts (typically one veterinarian, one expert in animal care, and one expert in zoo management and operations) and then reviewed by a panel of twelve experts before accreditation is awarded. This accreditation process is repeated once every five years.
The AZA estimates that there are approximately 2,400 animal exhibits operating under USDA license as of February 2007; fewer than 10% are accredited.
[13]
Special zoos and related facilities
Some zoos concentrate on animals of
geographical regions, on animals of the water (
aquarium) or attempt to exhibit their animals in a different way. Some of these institutions, mainly those who evolved from former
amusement parks, connect entertainment elements with exhibiting live animals.
Wild animal parks
Wild animal parks are larger than the classical zoo. The first of this new kind of animal park was
Whipsnade Park which opened in 1931 in
Bedfordshire,
England. This park, owned by the
Zoological Society of London, covers 600 acres (2.4 km²) and is still one of
Europe's largest wildlife conservation parks where animals are kept within sizeable enclosures. Since the early 1970s a 1,800-acre parcel (7 km²) in the Pasqual Valley near
San Diego also accommodates a remarkable zoo, the
San Diego Wild Animal Park that is run by the ''Zoological Society of San Diego''. Another zoo comparable to these wild animal parks is the
Werribee Open Range Zoo in
Melbourne,
Australia, focusing on displaying animals living in a wide open savanna. This 500-acre zoo is managed by the Zoological Parks and Gardens Board which also manages
Melbourne Zoo. One of only 2 American state supported zoo parks is the 535-acre
North Carolina Zoo located in
Asheboro,
North Carolina.
Public aquaria
The first
public aquarium was opened in London Zoo in 1853. This was followed by the opening of public aquaria in Europe (for example, Paris 1859, Hamburg 1864, Berlin 1869, Brighton 1872) and the United States (Boston 1859, Washington 1873, San Francisco Woodward's Garden 1873, New York Battery Park 1896). In 2005 the non-profit
Georgia Aquarium with more than 8 million US gallons (30,000 m³; 30,000,000 liters) of marine and fresh water, and more than 100,000 animals of 500 different species opened in
Atlanta, Georgia. The aquarium's specimens include
whale sharks and
beluga whales.
Animal theme parks
An animal theme park is a combination of an
amusement park and a zoo, mainly for entertaining and commercial purposes.
Marine mammal parks such as
Sea World are more elaborate
dolphinariums keeping
whale species and containing additional entertainment attractions. Another kind of animal theme park opened in 1998 -
Disney's Animal Kingdom in
Orlando, Florida. This commercial park established by the
Walt Disney Company is similar to wild animal parks according to size (550 acres, 2 km²), but differs in intention and appearance since it contains more entertainment and amusement elements than the classical zoo, such as a stage shows, roller coasters, and mythical creatures. Another famous one is the
Marineland in Niagara Falls, Ontario, Canada.
