Back to Animals

A zoo can be an awesome place to see animals first hand and learn about what they eat, their habits, environment, and all sorts of other interesting facts about animals. Another name for a zoo is zoological garden.

Today zoos are becoming better and better places for animals. In the past some zoos were somewhat cruel to animals. Placing animals in environments they were not suited for and often not keeping the animal's best interest in mind. However, today many zoos do wonderful work in animal research and take great care of their animals.

Photo by Ducksters

Some good things that many Zoos do today include:

Acting as sanctuaries for endangered animals. They provide a safe environment for animals that are being threatened by changes in the environment. Often zoos will work to breed and maintain endangered animal populations. Sometime animals are nearly extinct in the wild and the only place they survive is in zoos.

Education on wildlife. Zoos provide a great opportunity for us to learn more about creatures from distant lands.

Research on wildlife and how we can help animals survive radical changes. Zoos do veterinary medicine research as well.

Today's modern zoos house animals in enclosures that are similar to the animal's natural habitat. This can include buildings made for nocturnal animals where they are bright at night, so the animals can sleep, and dark during the day, so zoo visitors can see the animals moving about. Also, climates are controlled in some zoo enclosures for animals like penguins and polar bears. Many zoos have great open spaces as well where animals may graze together. Some zoos have an area where you can take a mini-safari or ride around in a truck or bus to hopefully see the animals up close.

Perhaps the most famous zoo is the San Diego Zoo in Southern California. Many modern zoo practices were pioneered at the San Diego Zoo. The largest zoo in number of animals is the Bronx Zoo with over 6000 animals. The largest zoo in land size is the North Carolina Zoo with 535 acres.

Seeing an elephant, giraffe, lion, polar bear, penguins, seals, or other incredible creatures at the zoo can be an amazing experience. Be sure to check out your local zoo and get the opportunity to see some awesome animals and learn more about nature.

Another great place to see animals, similar to a zoo, is at an aquarium. Most states have an aquarium where they display all sorts of fish and some sea mammals.More on endangered species:

Real sanctuaries are safe, comfortable places for animals to live after they've been rescued from not-so-nice places like circuses or laboratories. People can sometimes visit these sanctuaries, which is an awesome way to learn about and see animals without supporting businesses that hurt them, like roadside zoos or wildlife parks. Roadside zoos and wildlife parks use animals to make money. It's confusing because they sometimes call themselves "sanctuaries" or "rescues" to bring in more customers, because they know that people don't want to visit roadside zoos, but they're being dishonest when they do that.

It's important not to get these horrible places confused with actual sanctuaries. But how can you tell the difference? It's easy! There are a few simple questions you can ask about a place to figure out whether it's helping or hurting animals the animals who live there.

You can find answers to these questions by browsing a facility's website and social media pages (your parents can help):

1. How are animals housed?

Real sanctuaries make sure that an animal's living space is as close to their natural habitat as possible. Animals should live with others of their own kind so they can have friends. It's mean to keep them all alone in small, dirty pens with concrete floors and nothing to do-and you should stay away from places like that.

2. What kinds of activities do the animals get to do?

The animals' living area should have lots of ways for them to play and enjoy themselves! For example, there should be a large structure for chimpanzees to climb on, water for bears to soak and splash in, and large fields for roaming and exploring. Animals need these things if they're going to be healthy, happy, and comfortable.

Animals should also live with others of the same species so they can communicate with each another easily and form relationships and groups. In many sanctuaries, the animals who already live there help teach the newcomers how to get back in touch with their natural instincts and enjoy life again.

3. How big is the facility?

Animals should be given enough space to explore, roam, climb, and forage. And a real sanctuary NEVER takes the animals out of the facility to show them off.

4. Are visitors allowed to touch or hold the animals?

True wild-animal sanctuaries (with big cats, bears, primates, or wolves) NEVER allow visitors to touch or hold the animals, even babies, and that includes taking photos with them. This would be scary for the animals and dangerous to the visitors, too!

5. Where did the animals come from?

The animals who live there probably came from a place where they were mistreated, so they have a sad and painful past. The staff will want to share each animal's story so that visitors can learn about the various places that hurt animals (like laboratories, circuses, and roadside zoos). Real sanctuaries provide animals with a permanent home for the rest of their life. They NEVER trade, borrow, or loan animals.

6. Does the facility breed animals?

Sanctuaries NEVER breed animals, meaning that they don't make any of the animals have babies. Places that do breed animals are using them to make money-that's not right, and that's not a sanctuary.

7. What is it like to visit a sanctuary?

Most sanctuaries only allow very limited visits. Usually a guide takes people on a small tour of the place and doesn't let them walk around by themselves.

8. Is it accredited?

True sanctuaries are accredited by the Global Federation of Animal Sanctuaries (GFAS), a group that makes sure sanctuaries follow strict rules to protect the animals who live there, like the ones listed above.
*****
All living, feeling beings deserve a comfortable place to live where people aren't always staring at them. A true sanctuary puts the needs and wants of the animals first. So if you care about animals, NEVER visit a roadside zoo or a wildlife park, and explain to your friends and family why places like that are bad for animals!

The N.C. Zoo is one of only two state-operated zoos in the country. While more than 60 percent of its operating budget comes from the state, all of its conservation, research and education programs - and even the animals exhibited at the park - are purchased with private funds raised by the North Carolina Zoological Society.

Karen Brown with the Zoo Society says the "Adopt an Animal" program features a list of animals that can be "adopted" for a year.

Those who "adopt" an animal get a certificate, a photo of the animal and a fact sheet about the species.

Funds raised through the program benefit the Zoo's Animal Enrichment Program, which allows the Zoo to pay for additional training for zookeepers as well as purchase treats for the animals.

Some of the most popular animals for "adoption" are the African elephant, the polar bear, the zebra, the giraffe and the chimpanzee.

For more information about "adopting" zoo animals, visit nczoo.com or call the Zoo Society at (336) 879-7250.

This piece is a response to "The Modern Zoo" from the May 2008 issue of Teen Ink. I volunteer at the Cleveland Metroparks Zoo and have gotten to know its keepers, veterinary staff, and other workers. According to the writer of "The Modern Zoo," staff torture animals, do not provide adequate living space, and keep the animals merely to entertain. In my three years of volunteering, I have never seen, nor had any reason to suspect, any foul play at my zoo. The allegations in "The Modern Zoo" that all zoos are inhumane and cruel is false, I believe.

According to the article in Teen Ink, "Zoos claim to educate visitors. Yet we've all seen the one-sentence signs that describe monkeys. What can be learned from this? Certainly not enough to justify inhumane captivity." One-sentence signs are not the end of zoos' efforts to educate. At my zoo an entire department is devoted to educating the public about conservation of animals and our planet. If zoos didn't care about education, why would they have this? While exhibits may display signs with brief information, staff work daily at the zoo to educate visitors about conservation and other critical topics.

Some zoo employees visit schools and businesses to educate the public about how to be more responsible with our environment. This department even organizes conservation projects around Ohio, such as the community effort to remove waste from Big Creek. Volunteers spent a day restoring the creek to a more healthy ecosystem. The zoo is also part of a national conservation campaign called Year of the Frog, dedicated to saving amphibian species from extinction. Zoos put forth tremendous effort to educate people, and to say that they do not is just not true in my experience.

"Zoo animals endure inadequate living conditions with no space," claims the article. It's not fair to make this generalization. My own zoo, for example, is planning a one-of-a-kind, spacious exhibit for its elephants. The exhibit encompasses many acres, and will be large enough to support a breeding population. If zoos didn't care about adequate space for their animals, why would they waste time raising millions of dollars to build this type of exhibit? Also, my zoo cares a lot for its animals; it houses the second oldest hippo in North America and its polar bears are twice the age of those in the wild.

I witnessed a life-saving surgery on a 13-year-old wolf. Veterinarians worked for two hours to save his life. Thirteen is very old for a wolf. Zoos do care for their animals, and do what they can to keep them strong and healthy.

"These animals are simply meant to entertain," claims "The Modern Zoo." That too is false. At the Cleveland Metroparks Zoo, animals are never forced to do anything for the sake of visitors' entertainment. We believe in positive animal/ human interaction. Zoo staff never force or coerce an animal due to this policy.

The author of "The Modern Zoo" is obviously very passionate in his opinion about zoos. I am also very passionate. I have not written this to personally attack him. Rather, I am simply stating facts. "The Modern Zoo" paints zoos as cruel, inhumane facilities, but it is both unfair and untrue to claim this about all of them. Many have state-of-the-art veterinary facilities and work hard to save endangered species.

I hope that readers will see that zoos seek to protect and save endangered species, as well as educate and encourage the public to do the same.

Why Zoos Matter

We at the Saint Louis Zoo are passionate about the work we do. We not only care about the work we're doing, we are fostering animals that are threatened or endangered and supporting their perpetuation into the future.

Making a Difference

The world around us is changing fast. Species of wildlife are facing global extinction on a massive scale. About 41 percent of all amphibian species and 26 percent of all mammals are now threatened with extinction, and fully half of the world's primates - our closest relatives - teeter on the edge of existence. We face the loss of one in eight of all bird species. Overall, the extinction rate has increased a hundred-fold over the last century, and today we estimate that over 18,000 species face oblivion. Zoos are in a unique position to make a difference. Zoos are focused on offering the very best possible nutrition, enrichment and environment for animals in their care.

The many committed people at zoos care deeply about animals, working with an incredible variety of species, from one-celled creatures to elephants. Our research on behavior, reproductive biology, nutrition, animal health and genetics is valuable to wildlife managers, field researchers and other scientists.

For example, the Saint Louis Zoo has been doing a mother/infant bonding study with antelope and other hoofed animals at Red Rocks for 14 years. The data we've gathered - how often and when a species typically nurses, who initiates nursing, proximity, grooming, nuzzling - has provided information to field researchers that would be hard to come by otherwise.

We are animal experts

Zoo professionals are experts on breeding small populations of endangered species. That knowledge, too, has become valuable to scientists working with wildlife populations. Nowadays animals in wild habitats are often found in small, fragmented groups because of agriculture, logging or other human activity.

We collaborate with organizations worldwide on conservation breeding, habitat preservation, community development, public education and research.

Explore our conservation efforts

From Fence to Field

In 2004, the Saint Louis Zoo established the WildCare Institute to work in conservation hotspots locally and around the globe.

From Forest Park and Missouri streams to the Horn of Africa or the coastline of Peru, the Zoo is taking a holistic approach to wildlife conservation. While the Zoo has been involved in helping save endangered species for decades, our goal today is create a sustainable future for wildlife and for people around the world. Ultimately, we need to help save the ecosystems on which animals and humans depend. WildCare Institute addresses three key ingredients in conservation success: wildlife management and recovery, conservation science, and support of the human populations that coexist with wildlife.

Connecting people to animals

People learn at zoos. They learn in our formal classes, lectures, camps, teacher workshops, distance learning, zoo tours, overnights and outreach programs. Informally they learn from keeper chats, docent volunteers, interpreters, signage and special exhibits. Most important, they learn from observing zoo animals.

On a scale of 1 to 10, our visitors rate their educational experience at the Saint Louis Zoo as a 9.1.

Unique Experiences.

Zoos are a place where families can have unique experiences together every time they visit. Today's families are more conscious than ever of the need to teach their children about the natural world and respect for living creatures.

Why do people come to the zoo?

Why do zoos matter?

Because we care.

We want to keep this planet's amazing wildlife around for future generations.

/ CBS News

WASHINGTON - The National Zoo has a reputation as a leader in animal care, science and cute photo opportunities such as the naming of Bao Bao the baby panda earlier this month.

But a CBS News investigation has learned that behind the scenes, there are insider allegations of mismanagement involving animal care. Five sources with more than 35 years' combined experience at the National Zoo have raised concerns to CBS News about recent animal injuries, deaths and escapes.

The sources don't want to be identified for fear of retaliation. They say problems began last year when the zoo decided to double the population of the Cheetah Conservation Station, adding a half dozen new species but no extra space. Besides cheetahs, the CCS also houses zebras, gazelles and other species.

CBS News asked animal biologist and ethicist Marc Bekoff to look at the complaints. He was an independent reviewer of a 2005 National Academy of Sciences investigation of the zoo that found "systemic problems at the highest levels."

Of the newly raised issues, Bekoff said: "I call it 'fetch and pray.' You get the animals and then you pray that the project will work out."

The CCS' new animal mix didn't always work out. Issues identified by the zoo sources include two newly acquired hornbill birds that were kept in an indoor shack for seven months because their exhibit yard wasn't ready. Only after a volunteer complained were the birds allowed in an outdoor space. But the wallaby that had to share its yard with these new arrivals became frightened, according to sources, bloodied its nose and spent much of its time frightened and hiding.

One of two new red river hogs quickly became malnourished and died of an infection. The other hog, along with oryxes and sitatungas (two types of antelopes), sometimes became overly aggressive when mixed together, and some were injured in vicious fights.

It's not unusual for animals to spar, but the zoo sources say management failed to predict easily foreseeable conflicts between species and genders, and had ineffective backup plans for separating and protecting the animals when the conflicts arose.

"It's no surprise to me as a field biologist that so many of them do not work out," Bekoff told CBS News. "They're just too hastily put together and they're not well thought through."

Zoo spokeswoman Pamela Baker-Masson says the National Zoo meets the highest industry standards and the animals always receive the best care.

"We take great care in introducing our animals to these various habitats and transitioning them. Ideally, these things wouldn't happen, of course," said Baker-Masson. "I think my colleagues were very well aware and they know these species and they know how to take care of these species. ... Every single animal has a very specific course of action and a plan."

Bekoff says the zoo's plans appear to have been inadequate. "They should only be able to get the animals when it can be shown that they can properly house them and care for them."

Two animals in the CCS, a Dama gazelle and a pregnant kudu (another type of antelope), died when they got spooked on separate occasions and ran into barriers in their confined spaces, breaking their necks.

The gazelle death happened last month after a zebra attacked a veteran zookeeper. The commotion apparently frightened the gazelle, which is on the endangered species list. Zoo sources say it wasn't found for hours. The pregnant kudu died last June. Zoo sources say as the animal lay suffering with a broken neck, workers were unable to quickly locate necessary veterinary records.

Baker-Masson says Dama gazelles and kudus are skittish animals by nature and were housed in adequate spaces that met the requirements of the American Zoological Association, which recently re-accredited the facility.

As for the hornbill birds that were keep indoors for eight months, Baker-Masson says the space was "more than adequate and it gave the staff a very good amount of time to prepare and work with the hornbills" but "ideally they would have [had] access to their outdoor yard space more quickly."

Bekoff calls the lengthy indoor confinement "totally unacceptable."

"There's not one single excuse that I would accept," he said. "Basically this is a form of animal abuse and animal neglect. ...They get an 'F' in this project.'

Zoo sources also expressed concern about two escapes from the CCS: a vulture whose wings were allegedly not properly clipped and a red panda who managed to climb out of its exhibit. Both animals were later recaptured and zoo officials say the failures that allowed the escapes have been fixed.

CBS News has learned that the zoo convened a task force last summer to investigate the internal complaints about animal care at the CCS. The task force made findings last August and Baker-Masson says some of its recommendations are already being implemented.

Zoo officials refused CBS News' repeated requests to release the task force report even though, under public records law, it's considered public material.

As to why the National Zoo is withholding the information, Baker-Masson provided a number of rationales. First, she said that the task force report was still only a draft, four months after it was scheduled to be completed. However, when CBS News asked for the draft, she would not provide that either.

Later, in an interview, Baker-Masson said that the task force report is finished, but that the zoo isn't ready to release it.

"We're more than happy to [release the task force report]," Baker-Masson told CBS News. "But we have to do it in a thorough and process-oriented way that makes sense."

She acknowledged that some of the concerns investigated were founded.

"Absolutely," Baker-Masson said. "Anytime a concern is raised, it's looked at very seriously and we have to examine, you know, what changes are appropriate for that particular species, what changes are appropriate for the staff, what changes are appropriate for the facility itself. So yes, absolutely, some changes have been made."

Another incident the zoo is keeping mum about is the November zebra attack on the zookeeper. Baker-Masson says that AZA standards require that there always be a barrier between a keeper and zebras, which can inflict serious bite wounds. But the zoo says three weeks after the attack, it still has not identified how the zebra got to the keeper and it would not release the incident report or other public information about it. The injured zookeeper was recently released after several weeks in the hospital.
