The National Zoological Park, commonly known as the National Zoo, is one of the oldest zoos in the United States. It is part of the Smithsonian Institution and does not charge for admission. Founded in 1889, its mission is to "provide engaging experiences with animals and create and share knowledge to save wildlife and habitats".
The National Zoo has two campuses. The first is a 163-acre (66 ha) urban park located at Rock Creek Park in Northwest Washington, D.C., 20 minutes from the National Mall by MetroRail. The other campus is the 3,200-acre (1,300 ha) Smithsonian Conservation Biology Institute (SCBI; formerly known as the Conservation and Research Center) in Front Royal, Virginia. On this land, there are 180 species of trees, 850 species of woody shrubs and herbaceous plants, 40 species of grasses, and 36 different species of bamboo. The SCBI is a non-public facility devoted to training wildlife professionals in conservation biology and to propagating rare species through natural means and assisted reproduction. The National Zoo is accredited by the Association of Zoos and Aquariums (AZA).
The two facilities host about 1,800 animals of 300 different species.About one-fifth of them are endangered or threatened. Most species are on exhibit at the Rock Creek Park campus. The best-known residents are the giant pandas, but the zoo is also home to birds, great apes, big cats, Asian elephants, insects, amphibians, reptiles, aquatic animals, small mammals and many more. The SCBI facility houses between 30 and 40 endangered species at any given time depending on research needs and recommendations from the zoo and the conservation community. The zoo was one of the first to establish a scientific research program. Because it is a part of the Smithsonian Institution, the National Zoo receives federal appropriations for operating expenses. A new master plan for the park was introduced in 2008 to upgrade the park's exhibits and layout.
The National Zoo is open every day of the year except for December 25 (Christmas Day).
The zoo first started as the National Museum's Department of Living Animals in 1886.By an act of Congress in 1889, for "the advancement of science and the instruction and recreation of the people" the National Zoo was created. In 1890, it became a part of the Smithsonian Institution. Three well-known individuals drew up plans for the zoo: Samuel Langley, third Secretary of the Smithsonian; William T. Hornaday, noted conservationist and head of the Smithsonian's vertebrate division; and Frederick Law Olmsted, the premier landscape architect of his day. William Temple Hornaday was the curator of all 185 animals when the park was first opened. Together, they designed a new zoo to exhibit animals for the public and to serve as a refuge for wildlife, such as bison and beaver, which were rapidly vanishing from North America.
For the first 50 years, the National Zoo, like most zoos around the world, focused on exhibiting one or two representative exotic animal species. The number of many species in the wild began to decline drastically because of human activities. Sometimes animals became unexpectedly available. In 1899, the Kansas frontiersman Charles "Buffalo" Jones captured a bighorn sheep for the zoo.The fate of animals and plants became a pressing concern. Many of these species were favorite zoo animals, such as elephants and tigers; hence the staff began to concentrate on the long-term management and conservation of entire species.
In the mid-1950s, the zoo hired its first full-time permanent veterinarian, reflecting a priority placed on professional health care for the animals. In 1958, Friends of the National Zoo (FONZ) was founded. The citizen group's first accomplishment was to persuade Congress to fund the zoo's budget entirely through the Smithsonian; previously, the zoo's budget was divided between appropriations for the Smithsonian and the District of Columbia. Congressional funding placed the zoo on a firmer financial base, allowing for a period of growth and improvement. In 2006, Congress approved an additional 14.6 million dollars for renovations in both facilities.FONZ incorporated as a nonprofit organization and turned its attention to developing education and volunteer programs, supporting these efforts from its operation of concessions at the zoo, and expanding community support for the zoo through a growing membership which annually raises between $4 million and $8 million for the zoo.
In the early 1960s, the zoo turned its attention to breeding and studying threatened and endangered species. Although some zoo animals had been breeding and raising young, it was not understood why some species did so successfully while others did not. In 1965, the zoo created the zoological research division to study the reproduction, behavior, and ecology of zoo species, and to learn how best to meet the needs of the animals.
In 1975, the zoo established the Conservation and Research Center (CRC). In 2010, the complex was renamed the Smithsonian Conservation Biology Institute (SCBI), a title also used as an umbrella term for the scientific endeavors that take place on both campuses. On 3,200 acres (13 km2) in the Virginia countryside, rare species, such as Mongolian wild horses, scimitar-horned oryx, maned wolves, cranes, and others live and breed in spacious surroundings. SCBI's modern efforts emphasize reproductive physiology, analysis of habitat and species relationships, genetics, husbandry and the training of conservation scientists.
The zoo's last hippopotamus, Happy, was transferred to Milwaukee County Zoo in 2009 to make space for Elephant Trails.
Expanding knowledge about the needs of zoo animals and commitment to their well being has changed the look of the National Zoo. Today, animals live in natural groupings rather than individually. Rare and endangered species, such as golden lion tamarins, Sumatran tigers, and sarus cranes, breed and raise their young – showing the success of the zoo's conservation and research programs.The zoo's research team studies animals both in the wild and at the zoo. Its research encompasses reproductive biology, conservation biology, biodiversity monitoring, veterinary medicine, nutrition, behavior, ecology, and bird migration.
The National Zoo has developed public-education programs to help students, teachers and families explore the intricacies of the animal world. The zoo also designed specialized programs to train wildlife professionals from around the world and to form a network to provide crucial support for international conservation. The National Zoo is at the forefront of the use of web technology and programming to expand its programs to an international virtual audience.
The National Zoo has been the home to giant pandas since Ling-Ling and Hsing-Hsing arrived at the zoo in 1972. Since 2000, Mei Xiang and Tian Tian also lived there. On July 9, 2005, Mei Xiang gave birth to Tai Shan, who went to China in February 2010. On August 23, 2013, Mei Xiang gave birth to Bao Bao, who still resides at the zoo.[ needs update ] On August 22, 2015, Mei Xiang gave birth to Bei Bei, who still resides at the zoo.
Plans for the future include modernizing the zoo's aging facilities and expanding its education, research and conservation efforts in Washington, Virginia and in the wild. As part of a 10-year renewal program, Asia Trail – a series of habitats for seven Asian species including sloth bears, red pandas, and clouded leopards – was created. Elephant Trails, opened in 2013, provides a new home for the zoo's Asian elephants. Kids' Farm exhibit, opened in 2004, was slated for closure in 2011 but is to remain open for another 10 years following a donation to the exhibit.
The zoo, which is supported by tax revenues and open to everyone, attracts 2 million visitors per year, according to the Washington Post in 2005.[ citation needed ]
The National Zoo has a Federal Law Enforcement Agency deployed on its grounds: the National Zoological Park Police (NZPP), which consists of full-time Law Enforcement Officers. The NZPP is an agency that has been recognized by the United States Congress and is one of five original police agencies within the District of Columbia with full police powers. They work very closely with the Metropolitan Police Department, the United States Park Police, Department of State, Capital Police, Federal Bureau of Investigation, and the Department of Defense. The agency is considered the first line of defense in the event of any crisis.[ citation needed ]
Dennis W. Kelly was named director of the zoo on February 15, 2010, overseeing both campuses. Kelly succeeded John Berry, who was the National Zoo director for three years until February 2009, when he resigned to become the director of the U.S. Office of Personnel Management under the Obama Administration. Steven Monfort, the zoo's associate director for conservation and science, served as the acting director between February 2009 and February 2010. Kelly retired as the zoo's director in November 2017, Steven Monfort was named acting director.
The zoo's Giant Panda Habitat features three outdoor areas with animal enrichment, as well as an indoor area with a rocky outcrop, a waterfall, and viewing areas. The zoo's pandas, named Mei Xiang and Tian Tian, are on loan from the China Wildlife Conservation Association, and will live at the zoo until 2020.They are the focus of a research, conservation, and breeding program that aims to preserve the species. Mei Xiang and Tian Tian successfully had a male cub, named Tai Shan, in 2005. Tai Shan currently lives at the Bifengxia Panda Base in Sichuan, China, taking part in Bifengxia's breeding program. On September 16, 2012, Mei Xiang gave birth to another cub, but the cub died six days after its birth. On August 23, 2013, Mei Xiang gave birth to two cubs; one, a female named Bao Bao, survived, while the other was stillborn. The pandas live at the Fujifilm Giant Panda Habitat, a state-of-the-art indoor and outdoor exhibit. The exhibit is designed to replicate the rocky, lush terrain of the pandas' natural habitat. Mei delivered two cubs in August 2015; one died a few days later. Both cubs, fraternal twins, were sired by Tian Tian; the surviving male was given the name Bei Bei on September 25, 2015 and was on public exhibit in January 2016.
A group of Asia-themed exhibits opened in 2006. Along with the giant pandas, the area also displays sloth bears, fishing cats, red pandas, a clouded leopard, Asian small-clawed otters, and Asian elephants. Next to the pandas is an exhibit for Japanese giant salamander. However, in mid-2016, the salamander died and the exhibit space is currently unoccupied;the zoo keeps members of the species off-exhibit in the reptile house.
In spring 2008, the National Zoo began construction on Elephant Trails, a new home for its 7 Asian elephants. The first part of the $52 million project opened in September 2010, expanding the zoo's former elephant area with a 5,700-square-foot (530 m2) barn, two new yards (one with a pool), and a quarter-mile (400 m) walkway through woods, a total of 1.9 acres (0.77 ha) of outdoor space, bringing the total size of Elephant Trails to 2 acres (0.81 ha). Elephant Trails: A Campaign to Save Asian Elephants is a comprehensive breeding, education, and scientific research program. It is designed to help scientists care for elephants in zoos and save them in the wild. The Elephant House was closed to the public from September 14, 2009 until late March 2013 for construction of the second phase of Elephant Trails. This includes the Elephant Community Center, an indoor exhibit with many interpretive signs and graphics.
Lemur Island is a moated island that is home to a group of ring-tailed lemurs, red-fronted lemurs and black-and-white ruffed lemurs.
Uncle Beazley , a fiberglass Triceratops that Louis Paul Jonas created for the DinoLand pavilion at the 1964 New York World's Fair, can now be seen near the island. The life-size statue, which had been located on the National Mall near the National Museum of Natural History until 1994, is named for a dinosaur in the 1956 children's book, The Enormous Egg, by Oliver Butterworth and in the book's 1968 television movie adaptation, in which the statue appeared.
The majority of the zoo's smaller mammal species live in the Small Mammal House. The species on display include golden lion tamarins, golden-headed lion tamarins, pale-headed saki monkeys, Geoffroy's marmosets, red ruffed lemurs, black-footed ferrets, dwarf mongooses, meerkats, brush-tailed bettongs, striped skunks, La Plata three-banded armadillos, screaming hairy armadillos, sand cats, fennec foxs, naked mole-rats, southern tamanduas, rock hyraxs and several others.
A sister pair of White-nosed coatis and a male, female pair of black howler monkeys can be found behind the building, while a pair of bennett's wallabies can be found along the side of the building.
Despite not being mammals, two Von der Decken's hornbills and a male green aracari can be found in the building.
The American Trail exhibit houses a variety of North American species. These include five California sea lions, four grey seals, one harbor seal, three North American beavers, two North American River Otters, two bald eagles, two common ravens, three brown pelicans, and two grey wolves.After facing severe threats, the majority of American Trail species have rebounded thanks to conservation efforts. Many of the residents of American Trail have been listed as endangered. All of plants in the animal enclosures on American Trail exhibit are native to North America.
The exhibit also features a cafe called Seal Rock Cafe, which offers dishes crafted from local, seasonal, and sustainable ingredients. Menu items include Best Aquaculture Practices (BAP) certified shrimp and Marine Stewardship Council (MSC) certified fish.The American Trail was recently renovated and reopened in late summer 2012.
The Great Ape House is separated into two sets of enclosures. One houses seven bornean orangutans (two males named Kiko and Kyle; four females named Lucy, Batang, Iris and Bonnie; and a male infant named Redd, born in 2016). The other houses seven western lowland gorillas (four males named Baraka, Kojo, Kwame and Moke; As well as three females named Mandara, Kibibi and Calaya). The orangutans are allowed access to the Think Tank (see below) by travelling along the "O-Line", a series of high cables supported by metal towers that enable the orangutans to move between the two buildings. Kyle, Batang and Redd are Bornean orangutans and Kiko, Lucy, Iris and Bonnie are all hybrid orangutans.
The Think Tank is an area designed to educate visitors about how animals think and learn about their surroundings. The Think Tank features several interactive displays that teach visitors how zoologists conduct their studies. The zoo's orangutans (which are sometimes used in keeper demonstrations) are allowed to move from the Great Ape House to the Think Tank, and the building includes suitable enclosures for the apes should they choose to stay there. Other animals kept and studied in The Think Tank include brown rats, land hermit crabs, 4 Allen's swamp monkeys and 3 red-tailed monkeys. The zoo once had a population of Celebes crested macaques living in an outdoor cage.
Gibbon Ridge is an enclosure housing two different species of gibbon: two Northern white-cheeked gibbons (a male named Sydney and female named Tuyen), and two siamang (a male named Bradley and a female named Ronnie).
Great Cats is separated into three enclosures. The zoo rotates African lions, two Sumatran tigers (a female named Damai and a male named Sparky) and a male Amur Tiger named Pavel between the three exhibits.
One of the zoo's tigers, Soyono, was euthanized in November 2012. She was 19 years old, which is close to the limits of her life span. The tiger looked to be suffering from spondylosis, a degenerative spinal disorder, which afflicts big cats as they get older.
On January 24, 2014, the zoo's 10-year-old female lion, Nababiep, gave birth to three cubs in an eight-hour period. Two of the cubs survived, and were the first lion cub litter born at the zoo in four years, the third for Nababiep, and the fourth for the eight-year-old father, Luke. The birth followed the birth of two rare Sumatran tiger cubs to mother Damai on August 5, 2013.There are also two (currently indefinitely unoccupied) exhibits for bobcats and caracals.
This is an outdoor exhibit designed to mimic the African savanna and educate visitors about cheetahs and what is being done to preserve them in the wild. The main part of the Cheetah Conservation Station consists of two enclosures separated by a fence. One enclosures houses four South African cheetahs (both males; Justin/Gat [named for Justin Gatlin], Bakari, Donnie and Copley), while the other houses one male Grevy's zebra named Moyo. Other animals on display in the area include two scimitar-horned oryxs, four dama gazelles, two Rüppell's vultures, one sitatunga, three red river hogs, two male maned wolves named Mateo and Quito (a species native to South America), an Abyssinian ground hornbill and three lesser kudu. A female tammar wallaby named Maji had been on display until December 2013, when she was euthanized at the very old age of 18 (most do not live beyond 10).
This exhibit housed the zoo's collection of invertebrates. It was permanently closed to the public on June 22, 2014 due to inadequate funding.The zoo has mentioned they eventually want to build a hall of biodiversity which will include invertebrates. The zoo's Bird House is currently under renovation and once complete some invertebrates (such as Horseshoe crabs) will be included.
This South America-themed walk-through exhibit contains animal and plant species native to the Amazon basin. Animals on display include multiple species of freshwater stingrays, oscars, silver arowanas, Yellow-spotted Amazon river turtles, arapaimas, black pacus, red-bellied piranhas, white-eared titi monkeys, a Southern two-toed sloth, sunbitterns, red-crested cardinals, yellow-rumped caciques and many more.
The Amazonia science gallery is located on the lower level. Here visitors can learn about the zoo's efforts to protect species around the globe. Some of the species on display include Panamanian golden frogs, African clawed frogs, aquatic caecilians, barred tiger salamanders, grey tree frogs and many species of poison frogs. Located within the science gallery is the Coral lab. Many corals are on display along with clownfish, anemones, peacock mantis shrimp, warty frogfish and other species.
The Electric Fishes Demonstration Lab features a five-foot long electric eel. Bluntnose knifefish, elephant-nose knifefish and black ghost knifefish are also featured.
The zoo's reptile and amphibian house exhibits seventy species of reptiles and amphibians. These include Aldabra tortoises, radiated tortoises, spider tortoises, Cuban crocodiles, a Gharial, a Philippine crocodile, Eastern indigo snakes, Gaboon vipers, gila monsters, green anacondas, Burmese rock pythons, green tree pythons, Timor pythons, king cobras, northern copperheads, Eastern diamondback rattlesnakes, hellbenders, eastern red-backed salamanders, long-tailed salamanders, Alligator snapping turtles and many more.
Behind the building are exhibits for a Komodo dragon, Chinese alligators and a false gavial. In the front of the building is an exhibit for an American alligator named Wally.
As of 2017, [update] The Bird House is closed for renovations for "Experience Migration", an exhibition dedicated to migratory birds. Experience Migration will open in 2021.
The Kids' Farm is aimed primarily at children and housing domesticated livestock. The exhibit also features a "Pizza Garden" which grows traditional pizza ingredients. Animals kept in the Kids' Farm include alpacas, Ossabaw Island hogs, miniature Mediterranean donkeys, Hereford and Holstein cows, and Nigerian dwarf, Anglo-Nubian and San Clemente Island goats. In 2011, the zoo announced plans to close The Kids' Farm due to budgetary constraints. However, a $1.4 million donation from State Farm Insurance allowed the exhibit to remain open.
The zoo opened a new American Bison Exhibit on August 30, 2014 as part of their 125th anniversary celebration.The exhibit features two female bison, named Zora and Wilma, that were transported to the zoo earlier that year from the American Prairie Reserve in northeastern Montana.
Other animals in the zoo's collection include spectacled bears (near the Amazonia exhibit), Przewalski's horse, which is now gone] (in a yard adjacent to the Small Mammal house), North American porcupines (near the Great Cats exhibit), black-tailed prairie dogs (near the Great Cats exhibit) and Patagonian maras (near American Trail).
One of the most famous animals to have spent much of his life at the zoo was Smokey Bear, the "living symbol" of the cartoon icon created as part of a campaign to prevent forest fires. A black bear cub rescued from a fire, he lived at the zoo from 1950 until his death in 1976. During his time at the zoo, he had millions of visitors and an abundance of personal mail addressed to him – up to 13,000 letters a week – such that the U.S. Post Office designated a special zip code for correspondence addressed to him.
During his time at the zoo, he was "married" to Goldie Bear, with the hope that one of his offspring would continue to hold the title of Smokey Bear. When the pair produced no offspring, an orphaned bear cub was added to their cage. It was named "Little Smokey", with the announcement that the bear couple had "adopted" the new cub. In 1975, an official ceremony was held to recognize the retirement of Smokey Bear and the new title of "Smokey Bear II" for Little Smokey.Upon the death of the original Smokey Bear, The Washington Post printed an obituary, recognizing him as a "New Mexico native" who had resided in Washington, D.C. for many years, working for the government.
Coming off the heels of President Richard Nixon's historic 1972 visit to China, the Chinese government donated two giant pandas, Ling-Ling (female) and Hsing-Hsing (male), to the official United States delegation. First Lady Pat Nixon donated the pandas to the zoo, where she welcomed them in an April 1972 ceremony. The first giant pandas in America, Ling-Ling and Hsing-Hsing were among the most popular animals at the zoo.Ling-Ling died in 1992 and Hsing-Hsing in 1999. Although Ling Ling and Hsing Hsing had five cubs between 1983 and 1989, all died as infants.
A new pair of pandas, female Mei Xiang ("Beautiful Fragrance") and male Tian Tian ("More and More"), arrived on loan from the Chinese government in late 2000.The zoo paid an estimated 10 million dollars for the 10-year loan. On July 9, 2005, a male panda cub was born at the zoo. It was the first surviving panda birth at the zoo and the product of artificial insemination by the zoo's reproductive research team. The cub was named Tai Shan ("Peaceful Mountain") on October 17, 100 days after his birth; the panda went without a name for its first hundred days, in observance of a Chinese custom. Tai Shan is property of the Chinese government and was scheduled to be sent to China after his second birthday, although that deadline was extended in 2007 by two years. Tai Shan left Washington, D.C., on February 4, 2010, and was taken to the Ya'an Bifengxia Panda Base, part of the Wolong nature reserve's panda conservation center.
On September 16, 2012, Mei Xiang gave birth to another cub, believed by zoo officials to have been a female, which died after about a week. Initial results from a necropsy (animal autopsy) revealed the abnormal presence of fluid in the abdomen and also discoloration of the liver (hepatic) tissue of unknown etiology; the cub had managed to nurse before death because milk was found in its system. Zoo officials said that, while upsetting, they (and, by extension, the public) can hope to learn more about giant panda breeding, reproduction, and health as a result, and will work closely and cooperatively with their Chinese colleagues during the inquiry.[ citation needed ]
In January 2011, Dennis Kelly, director of the National Zoo, and Zang Chunlin, secretary general of the China Wildlife Conservation Association, signed a new Giant Panda Cooperative Research and Breeding Agreement, extending the zoo's giant panda program for five more years, further cementing the two countries' commitment to the conservation of the species. The new agreement, effective through December 5, 2015, stipulates that the zoo will conduct research in the areas of breeding and cub behavior.[ needs update ]
In the summer of 2013, Mei Xiang gave birth to a live female panda cub (Tian Tian is the father; a second cub was stillborn), named Bao Bao ("treasure" or "precious"; decided through a naming contest) on the 100th day of her existence. As of January 18,2014, [update] Bao Bao is on public exhibit and drawing crowds, greatly increasing zoo attendance and on-line views via PandaCam.
Mei Xiang gave birth in August 2015 to two live cubs; the smaller one died a few days later (keepers had to care for it after Mei decided to focus on the larger cub). Sperm from both Tian Tian and another male giant panda based in a China preserve was used. It was determined on August 28, 2015that both cubs were male and sired by Tian Tian. The larger, surviving cub was named Bei Bei ("precious treasure") on September 25, 2015. In celebration of a state visit, the name was selected by First Lady of the United States, Michelle Obama, and First Lady of the People's Republic of China, Peng Liyuan.
Bao Bao was healthy at that time, eating bamboo and special fruitsicle treats, having been separated from Mei at 18 months of age. She celebrated her second birthday in August 2015, shortly after the cubs were born. Her contract extended to August 2017. Bao Bao left the National zoo on February 22, 2017 for the Dujiangyan base of the China Panda Conservation and Research Center.
In partnership with Friends of the National Zoo (FONZ), a non-profit organization, the zoo holds annual fund raisers (ZooFari, Guppy Gala, and Boo at the Zoo) and free events (Sunset Serenades, Fiesta Musical). Proceeds support animal care, conservation science, education and sustainability at the National Zoo.
Friends of the National Zoo (FONZ), the zoo's membership program, is the partner of the National Zoological Park that has been providing support to wildlife conservation programs at the zoo and around the world since 1958. FONZ members receive free parking, discounts at the zoo's stores and restaurants, and Smithsonian Zoogoer, a magazine with the latest zoo news, research and photos.
FONZ's 40,000 members include about 20,000 families, largely in the Washington metropolitan area, and more than 1,000 volunteers. FONZ provides guest services, development support, education and outreach programs, concessions management, and financial support for research and conservation. FONZ also offers a summer day-camp at the Rock Creek Park facility, and a residential nature camp at SCBI in Front Royal.
The Smithsonian established its Conservation Biology Institute (SCBI) in 2010 to serve as an umbrella for its global effort to conserve species and train future generations of conservationists. Headquartered in Front Royal, Virginia, the facility was previously known as the National Zoo's Conservation and Research Center.
The SCBI facilitates and promotes research programs based at Front Royal, at the National Zoo in Washington and at field research and training sites around the world. Its efforts support one of the four main goals of the Smithsonian's new strategic plan, which advances "understanding and sustaining a biodiverse planet."
Conservation biology is a field of science based on the premise that the conservation of biological diversity is important and benefits current and future human societies.
The Institute consists of six centers:
The Smithsonian's National Zoo currently houses four species of lemurs: black-and-white ruffed lemurs (Varecia variegate), ring-tailed lemurs (Lemur catta) and red-fronted lemurs (Eulemur rufus) in their mixed species Lemur Island exhibit, ... .
Three lemur species live at the Zoo. Ring-tailed lemurs and a pair of red-fronted lemurs live on Lemur Island. ... .
This 25-foot long replica of a Triceratops ... was placed on the Mall in 1967. ...
The full-size Triceratops replica and eight other types of dinosaurs were designed by two prominent paleontologists, Dr. Barnum Brown of the American Museum of Natural History, in New York City, and Dr. John Ostrom of the Peabody Museum, in Peabody, Massachusetts. The sculptor, Louis Paul Jonas, executed these prehistoric animals in fiberglass, after the designs of Barnum and Ostrom, for the Sinclair Refining Company's Pavilion at the New York World's Fair of 1964. After the Fair closed, the nine dinosaurs, which weighed between 2 and 4 tons each, were placed on trucks and taken on a tour of the eastern United States. The Sinclair Refining Company promoted the tour for public relations and advertising purposes, since their trademark was the dinosaur. In 1967, the nine dinosaurs were given to various American museums.
This particular replica was used for the filming of The Enormous Egg, a movie made by the National Broadcasting Company for television, based on a children's book of the same name by Oliver Butterworth. The movie features an enormous egg, out of which hatches a baby Tricerotops ; the boy consults with the Smithsonian Institution which accepts Uncle Beasley for the National Zoo.
In total, the committee evaluated 74% of all megavertebrate deaths that occurred at the National Zoo from 1999 to 2003. The committee concluded that in a majority of cases, the animal received appropriate care throughout its lifetime. In particular, the committee’s evaluation of randomly sampled megavertebrate deaths at the Rock Creek Park facility revealed few questions about the appropriateness of these animals’ care, suggesting that the publicized animal deaths were not indicative of a wider, undiscovered problem with animal care at the Rock Creek Park facility.
