The Omaha's Henry Doorly Zoo and Aquarium is a zoo in Omaha, Nebraska, located at 3701 South 10th Street. It is accredited by the Association of Zoos and Aquariums and a member of the World Association of Zoos and Aquariums. Its mission is conservation, research, recreation, and education. In August 2014, TripAdvisor proclaimed Henry Doorly Zoo the "world's best zoo", leading San Diego Zoo and Loro Parque, based on an algorithmic assimilation of millions of reviews for 275 major zoos worldwide.
Omaha's Henry Doorly Zoo and Aquarium is nationally renowned for its leadership in animal conservation and research. Evolving from the public Riverview Park Zoo established in 1894, today the zoo includes several notable exhibits. It features the largest cat complex in North America; "Kingdoms of the Night" is the world's largest nocturnal exhibit and indoor swamp; the Lied Jungle is one of the world's largest indoor rainforests, and the "Desert Dome" is the world's largest indoor desert, as well as the largest glazed geodesic dome in the world. The zoo is Nebraska’s top paid attendance attraction and has welcomed more than 25 million visitors over the past 40 years.

The zoo originally began in 1894 as Riverview Park Zoo. Four years later, it had over 120 animals. In 1952, the Omaha Zoological Society was created with aims to improve the zoo. In 1963, Margaret Hitchcock Doorly donated $750,000. In doing so, she stipulated that the zoo be renamed in memory of her late husband, Henry Doorly, chairman of the World Publishing Company. Union Pacific helped the zoo lay down 2.5 mi (4.0 km) of track in 1968 with the inaugural run of the Omaha Zoo Railroad made on July 22, 1968.
Omaha's Henry Doorly Zoo and Aquarium has two rides that circumnavigate the zoo and a carousel. Skyfari, an aerial tram which opened in 2009, takes visitors from the Butterfly and Insect Pavilion to elephants and rhinos.
The zoo is adjacent to the former site of Rosenblatt Stadium. In 2011, the zoo began developing the land at former Rosenblatt Stadium to become the new parking area and visitor center, leaving a small memorial at the location of home plate. Rosenblatt was replaced by the new TD Ameritrade Park.

The Lied Jungle opened on April 4, 1992, at a cost of $15 million. It is one of the largest indoor rainforest exhibits in the world; it occupies an 80-foot (24 m) tall building that spans 1.5 acres (0.61 ha) and is located just inside the main entrance. This exhibit allows visitors to look out from behind a 50-foot (15 m)-tall waterfall.
Inside are 123,000 ft2 (2.82 acres; 11,400 m2) of floor space, of which 61,000 ft2 (1.4 acres; 5,670 m2) are planted exhibit space; 35,000 ft2 (0.8 acres; 3,250 m2) are a display management area; and 11,000 ft2 (0.25 acres; 1,020 m2) are an education area.
Visitors can walk along a trail on the floor of the jungle, as well as on a walkway around and above the animals. Along both trails, about 90 species can be found, including:
- Blue monkey (Cercopithecus mitis)
- Common squirrel monkey (Saimiri sciureus)
- Black howler monkey (Alouatta caraya)
- Pygmy hippopotamus (Choeropsis liberiensis)
- Scarlet macaw (Ara macao)

- Philippine crocodile (Crocodylus mindorensis)
- Note: Ring-tailed lemurs, red ruffed lemurs, and black-and-white ruffed lemurs were on display in the Lied Jungle, but were moved to the zoo's newest exhibit, Expedition Madagascar, in 2010 because they are from Madagascar.
Many different types of plant life also thrive throughout the jungle. The exhibit is broken up into sections by continent, including Asia, Africa, and South America.
Visitors to the jungle can view the indoor jungle through 90 ft (27 m) of floor-to-ceiling windows at the Durham's TreeTops Restaurant, which is next to the jungle. A portion of the electrical power needed for the jungle is provided by natural gas fuel cells. The jungle has won several awards, including "Single best zoo exhibit in the country" in 1994 by the Family Life Magazine; "Significant Achievement Award for Exhibit Design" in 1993 by the American Association of Zoological Parks and Aquariums; "Top ten designs in the world" in 1992 by Time, and "Top eight US engineering accomplishments" in 1992 by the National Society of Professional Engineers

Exploration Station at the Wild Kingdom Pavilion
The Wild Kingdom Pavilion has been transformed into the Exploration Station exhibit, serving as a safari-themed “Trail Head” where visitors begin their “wild” adventure at Omaha’s zoo. Mutual of Omaha's Exploration Station includes a detailed interactive map of the zoo and video previews of major attraction such as the Scott Aquarium, Lied Jungle, Desert Dome, and Hubbard Gorilla Valley and Orangutan Forest. The station also features the History of the Zoo, Explorer Zone Classroom, Discover Biodiversity area, a theater, and numerous live-animal displays and the animal demonstration stage.
Tree of Learning
The center of the Exploration Station features a 20-foot (6 m)-high netted tree, with free-flying birds. Below the tree includes water displays with turtles, archer fish, and more.
Mutual of Omaha's Wild Kingdom Pavilion Original Facility
Situated inside the zoo's main entrance, the 21,000-square-foot (2,000 m2) Mutual of Omaha's Wild Kingdom Pavilion was completed in the spring of 1987. The membership drive theme was “Go Zoo U”. More than 32,000 household membership were sold and over 600,000 visitors enjoyed this new complex its first year. The building currently houses reptiles, insects, amphibians, and small mammals, while also providing business offices, a 312-seat multimedia auditorium, and classrooms.
Small Animal Collection
The building's original public area, or living classroom, houses part of the zoo's reptile collection, as well as a large number of invertebrates. The animal collection represents the tremendous diversity in the animal kingdom, and includes tarantulas, turtles, snakes, hedgehogs, and other small animals.
Butterfly and Insect Pavilion
The Butterfly and Insect Pavilion is a 14,000-square-foot (1,300 m2), total-immersion exhibit located between the Scott Aquarium and the Giraffe Complex. Viewed from the sky, the exhibit resembles a winged insect.
The Simmons Aviary was opened in 1983, and is the world's third-largest free-flight aviary. It is home to about 500 birds from around the world. In this 4-acre (16,000 m2) exhibit, visitors see flamingos, ducks, swans, storks, cranes, spoonbills, ibis and egrets. The Aviary is 800 feet (240 m) long and rises to 75 feet (23 m) at the center. The structure is covered with 142,000 sq ft (13,200 m2) of two-inch nylon mesh that is supported by a system of cables and poles. The use of nylon instead of wire is a unique concept.
Expedition Madagascar opened May 7, 2010, and has many animals including lemurs, straw-coloured fruit bats, and giant jumping rats. The building of Madagascar gives the visitors a chance to learn more about an area of the world considered one of the top hotspots for biodiversity because it is home to the largest number of endemic, native only to this country, plant and animal species. Throughout the building, each exhibit is linked to ongoing projects in Madagascar.
- Ring-tailed lemur
- Red ruffed lemur
- Black-and-white ruffed lemur
- Black lemur
- Mongoose lemur
- Collared lemur
- Brown lemur
The zoo also features Lozier IMAX theater and many other exhibits. Other exhibits include Cheetah Valley, Hoofstock, Owen Sea Lion Pavilion, a petting zoo, the new Budgie Encounter, and many others. Many different animals have smaller, individual exhibits such as sea lions, elephants, and rhinos.
The Bill and Berniece Grewcock Center for Conservation and Research is a world-class research center at the zoo. The center has discovered several new species. The world's first in vitro-fertilized ("test-tube") gorilla resides at the zoo. The world's first artificially inseminated tiger was born in Omaha in 1991, followed by the world's first artificially inseminated gaur. The original 16,448-square-foot (1,528.1 m2) facility was constructed in 1996. In 2006, it underwent a $6 million expansion which brings the total space to 32,000 sq ft (3,000 m2).
The research center focuses on six areas:
- Education and technology transfer
- Conservation medicine
- Molecular genetics
- Reproductive physiology
A study led by Edward Louis, a conservation geneticist at the zoo, identified three new mouse lemurs (Simmons' mouse lemur, Mittermeier's mouse lemur, and Jolly's mouse lemur) with the first named after Lee Simmons, the zoo's director.
Rides and transportation
The Omaha Zoo Railroad is a 2.5-mile (4.0 km), 2 ft 6 in (762 mm) narrow gauge train that loops through the zoo. The railroad began operations on July 22, 1968, after the track was laid down by the Union Pacific railroad. The train operates with one of two oil-powered steam locomotives. Riva is the newest locomotive owned by the zoo despite being manufactured first. It is about twice as powerful as the #119 and is regularly used on weekends when more visitors are present. The #119 is the original locomotive for the zoo. A new locomotive named "Virgie" arrived in September 2008. This diesel is styled with a face resembling "Virgie". It supplemented the steam locomotives beginning in 2009.
The tram is a trackless tram that drives on the walkway paths around the zoo. It has four stops:
- Between the carousel and Dairy World
- Between the sea lions and the monkeys
- Between the giraffes and the hoofstock
- Between the Budgie Encounter and the okapi
Omaha's Henry Doorly Zoo and Aquarium opened the Skyfari in 2009. It is an aerial tram that runs from one stop at the Butterfly and Insect Pavilion to the rhinos. It goes over the African veldt (ostriches and giraffes), cheetahs, the railroad tracks, the Garden of the Senses, the koi lagoon, and the rhinos.
A carousel is available on which visitors can ride handcrafted recreations of wild animals.
The zoo offers many educational programs. The activities include school-involved programs, special "edzoocational" programs, zoo internships, animal-adoption, and volunteer work. Several programs include field trips, guided tours, educator workshops, and two-way internet video conferencing to bring the zoo to the classroom. The edzoocational programs are educational programs that are taught in a nontraditional way. These programs include overnight camp-outs at the zoo, scouting programs, birthday parties, and on-site speakers.
