A zoo (short for zoological garden ; also called an animal park or menagerie ) is a facility in which animals are kept within enclosures for public exhibition and often bred for conservation purposes.
87-602: The Virginia Zoological Park , commonly known as the Virginia Zoo , is a 53-acre (21 ha) zoo located adjacent to Lafayette Park in Norfolk, Virginia , United States. The zoo opened in 1900, and was accredited by the Association of Zoos and Aquariums (AZA) in 1987. In 1892, the City of Norfolk purchased the 65 acres (26 ha) that was currently occupied by Lafayette Park. In 1900,
174-513: A Seychelles giant tortoise , is thought to be the oldest living giant tortoise at the age of 192 years. Esmeralda, an Aldabra giant tortoise, is second at the age of 180 years, since the death of Harriet , a Galapagos giant tortoise, at 175. An Aldabra giant tortoise living on Changuu off Zanzibar is reportedly 198 years old. Mating takes place between February and May, and in July-September females lay between 9 and 25 hard-shelled eggs in
261-643: A menagerie or "zoological forest". The abbreviation "zoo" first appeared in print in the United Kingdom around 1847, when it was used for the Clifton Zoo , but it was not until some 20 years later that the shortened form became popular in the rhyming song " Walking in the Zoo " by music-hall artist Alfred Vance . The term "zoological park" was used for more expansive facilities in Halifax, Nova Scotia , Washington, D.C. , and
348-734: A 1,500-acre (6.1 km ) zoo called Ling-Yu, or the Garden of Intelligence. Other well-known collectors of animals included King Solomon of the Kingdom of Israel and Judah , Queen Semiramis and King Ashurbanipal of Assyria , and King Nebuchadnezzar of Babylonia . By the 4th century BCE, zoos existed in most of the Greek city states; Alexander the Great is known to have sent animals that he found on his military expeditions back to Greece. The Roman emperors kept private collections of animals for study or for use in
435-559: A 30 cm deep nest . Usually, less than half of the eggs are fertile. Females can produce multiple clutches of eggs in a year. After incubating for about eight months, the tiny, independent young hatch between October and December. In captivity, oviposition dates vary. Tulsa Zoo maintains a small herd of Aldabra tortoises and they have reproduced several times since 1999. One female typically lays eggs in November and again in January, providing
522-400: A Congolese pygmy , displayed in a cage with the chimpanzees, then with an orangutan named Dohong, and a parrot. The exhibit was intended as an example of the "missing link" between the orangutan and white man. It triggered protests from the city's clergymen, but the public reportedly flocked to see Benga. Humans were also displayed at various events, especially colonial expositions such as
609-482: A consequence, various management tools are used to preserve the space for the genetically most important individuals and to reduce the risk of inbreeding . Management of animal populations is typically through international organizations such as AZA and EAZA . Zoos have several different ways of managing the animal populations, such as moves between zoos, contraception , sale of excess animals and euthanization (culling). Contraception can be an effective way to limit
696-587: A difference in wildlife conservation and education. Humans were occasionally displayed in cages at zoos along with non-human animals, to illustrate the differences between people of European and non-European origin. In September 1906, William Hornaday , director of the Bronx Zoo in New York—;with the agreement of Madison Grant , head of the New York Zoological Society —had Ota Benga ,

Outside of the exhibits is an oyster restoration pond and a pond for wild birds. Zoo The term zoological garden refers to zoology , the study of animals. The term is derived from the Ancient Greek ζῷον , zōion , 'animal', and the suffix -λογία , -logia , 'study of'. The abbreviation zoo
870-573: A fountain, a wood-ornamented greenhouse, a forest area, and enclosures and buildings. The first zoological garden in Australia was Melbourne Zoo in 1860. In German states leading roles came Berlin (1841), Frankfurt (1856), and Hamburg (1863). In 1907, the entrepreneur Carl Hagenbeck founded the Tierpark Hagenbeck in Stellingen, now a quarter of Hamburg . His zoo was a radical departure from
957-649: A gas station. The animals may be trained to perform tricks, and visitors are able to get closer to them than in larger zoos. Since they are sometimes less regulated, roadside zoos are often subject to accusations of neglect and cruelty . In June 2014 the Animal Legal Defense Fund filed a lawsuit against the Iowa-based roadside Cricket Hollow Zoo for violating the Endangered Species Act by failing to provide proper care for its animals. Since filing

#17330846403351044-450: A lack of natural wild habitat in which to reintroduce animals. This highlights the importance of in situ conservation, or preservation of natural spaces, in addition to the utility of zoo captive breeding and reintroduction programs. In situ conservation and reintroduction programs are key elements to obtaining certification by reputable organisations such as the Association of Zoos and Aquariums (AZA). Efforts to clone endangered species in
1131-455: A matter of public interest in 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. From then on, zoo professionals became increasingly aware of the need to engage themselves in conservation programs, and
1218-448: A model of cooperation for conservation. Loaned animals usually remain the property of the original park, and any offspring yielded by loaned animals are usually divided between the lending and holding institutions. For decades the capture of wild animals or purchasing of animals has been broadly considered unethical and has not been practiced by reputable zoos. Especially in large animals, a limited number of spaces are available in zoos. As
1305-418: A new strategy that sets out the aims and mission of zoological gardens of the 21st century. When studying behaviour of captive animals, several things should however be taken into account before drawing conclusions about wild populations. Including that captive populations are often smaller than wild ones and that the space available to each animal is often less than in the wild. Conservation programs all over
1392-434: A place of refuge . Today, many zoos are improving enclosures by including tactile and sensory features in the habitat that allow animals to encourage natural behaviors. These additions can prove to be effective in improving the lives of animals in captivity. The tactile and sensory features will vary depending on the species of animal. There are animals that are injured in the wild and are unable to survive on their own, but in
1479-466: A popular tourist attraction. Another isolated population of the species resides on the island of Changuu , near Zanzibar . Other captive populations exist in conservation parks in Mauritius and Rodrigues . The tortoises exploit many different kinds of habitat, including grasslands , low scrub , mangrove swamps , and coastal dunes. A peculiar habitat has coevolved due to the grazing pressures of
1566-481: A population's breeding. However it may also have health repercussions and can be difficult or even impossible to reverse in some animals. Additionally, some species may lose their reproductive capability entirely if prevented from breeding for a period (whether through contraceptives or isolation), but further study is needed on the subject. Sale of surplus animals from zoos was once common and in some cases animals have ended up in substandard facilities. In recent decades
1653-617: A raised boardwalk over the "Asian forest", and a cave with views into the tiger and orangutan exhibits. Another viewing area allows underwater views of the otters and tigers. Named after the real life Okavango Delta in Africa, this exhibit opened in 2002. The animals here include Masai giraffes , Hartmann's mountain zebras , white rhinoceros , African lions , cheetahs , meerkats , Ankole-Watusi , eastern bongoes , yellow-backed duikers , red river hogs , ostriches , southern ground hornbills , Aldabra giant tortoises , Meller's chameleons and
1740-643: A small number of zoos. To solve this organizations like EAZA and AZA have begun to develop husbandry manuals. Many modern zoos attempt to improve animal welfare by providing more space and behavioural enrichments . This often involves housing the animals in naturalistic enclosures that allow the animals to express more of their natural behaviours, such as roaming and foraging. Whilst many zoos have been working hard on this change, in some zoos, some enclosures still remain barren concrete enclosures or other minimally enriched cages. Aldabra giant tortoise The Aldabra giant tortoise ( Aldabrachelys gigantea )
1827-547: A suitable alternative. Off-site conservation relies on zoos, national parks, or other care facilities to support the rehabilitation of the animals and their populations. Zoos benefit conservation by providing suitable habitats and care to endangered animals. When properly regulated, they present a safe, clean environment for the animals to increase populations sizes. A study on amphibian conservation and zoos addressed these problems by writing, Whilst addressing in situ threats, particularly habitat loss, degradation and fragmentation,

A colony of black-crowned night herons has regularly summered at the National Zoo in Washington, D.C. for more than a century. Some zoos may provide information to visitors on wild animals visiting or living in the zoo, or encourage them by directing them to specific feeding or breeding platforms. In modern, well-regulated zoos, breeding
2001-580: A year and have special programs for schools. They are organized by the Association of Zoos and Aquariums . Japan's first modern zoo, Tokyo's Ueno Imperial Zoological Gardens , opened in 1882 based on European models. In World War II it was used to teach the Japanese people about the lands recently conquered by the Army. In 1943, fearing American bombing attacks, the government ordered the zoo to euthanize dangerous animals that might escape. When ecology emerged as

The species is endemic to the Seychelles , with the nominate subspecies , A. g. gigantea native to Aldabra atoll. It is one of the largest tortoises in the world. Historically, giant tortoises were found on many of the western Indian Ocean islands, as well as Madagascar, and the fossil record indicates giant tortoises once occurred on every continent and many islands with
2262-896: Is a brown or tan in color with a high, domed shape. The species has stocky, heavily scaled legs to support its heavy body. The neck of the Aldabra giant tortoise is very long, even for its great size, which helps the animal to exploit tree branches up to a meter from the ground as a food source. Similar in size to the famous Galápagos giant tortoise , its carapace averages 122 cm (48 in) in length. Males have an average weight of 250 kg (550 lb). Females are generally smaller than males, with average specimens measuring 91 cm (36 in) in carapace length and weighing 159 kg (351 lb). Medium-sized specimens in captivity were reported as 70 to 110 kg (150 to 240 lb) in body mass. Another study found body masses of up to 132 kg (291 lb) most commonplace. This species
2349-414: Is controlled to maintain a self-sustaining, global captive population. This is not the case in some less well-regulated zoos, often based in poorer regions. Overall "stock turnover" of animals during a year in a select group of poor zoos was reported as 20%-25% with 75% of wild caught apes dying in captivity within the first 20 months. The authors of the report stated that before successful breeding programs,

In 2014 the Wrocław Zoo opened the Africarium , the only themed oceanarium devoted solely to exhibiting the fauna of Africa , comprehensively presenting selected ecosystems from
2610-587: Is widely referred to as Aldabrachelys gigantea , but in recent times, attempts were made to use the name Dipsochelys as Dipsochelys dussumieri . After a debate that lasted two years with many submissions, the ICZN eventually decided to conserve the name Testudo gigantea over this recently used name (ICZN 2013). This also affected the genus name for the species, establishing Aldabrachelys gigantea as nomen protectum . Four subspecies are currently recognized. A trinomial authority in parentheses indicates that
2697-531: The American Zoo Association soon said that conservation was its highest priority. In order to stress conservation issues, many large zoos stopped the practice of having animals perform tricks for visitors. The Detroit Zoo , for example, stopped its elephant show in 1969, and its chimpanzee show in 1983, acknowledging that the trainers had probably abused the animals to get them to perform. Mass destruction of wildlife habitat has yet to cease all over

Besides conservation of captive species, large zoos may form
3828-544: The United States, Europe, and Asia are frequently embedded in zoos and zoological parks. The position of most modern zoos in Australasia , Asia , Europe , and North America , particularly those with scientific societies, is that they display wild animals primarily for the conservation of endangered species , as well as for research purposes and education, and secondarily for the entertainment of visitors. The Zoological Society of London states in its charter that its aim
3915-737: The animals and visitors. Nocturnal animals are often housed in buildings with a reversed light-dark cycle, i.e. only dim white or red lights are on during the day so the animals are active during visitor hours, and brighter lights on at night when the animals sleep. Special climate conditions may be created for animals living in extreme environments, such as penguins. Special enclosures for birds , mammals , insects , reptiles , fish , and other aquatic life forms have also been developed. Some zoos have walk-through 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
4002-487: 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

Substandard enclosures can lead to decreased lifespans, caused by factors as human diseases, unsafe materials in the cages and possible escape attempts (Bendow 382). However, when zoos take time to think about the animal's welfare, zoos can become

This stands in contrast to most zoos publicly announcing animal births. Furthermore, while many zoos are willing to cull smaller and/or low-profile animals, fewer are willing to do it with larger high-profile species. Many animals breed readily in captivity. Zoos frequently are forced to intentionally limit captive breeding because of
