Ever aback Knut, the Berlin Zoo’s four-year-old arctic bear, died aftermost month, I’ve been wondering: How can I acquaint if a zoo is demography acceptable affliction of its animals?
This is a catchy question. Some beastly advocates altercate that zoos, by definition, are bad for agrarian animals. Alike so, there’s no catechism that assertive zoos amusement their animals bigger than others. Unfortunately, it can be difficult to acquaint the difference.
In the United States, zoos charge accept a authorization from the USDA, but this bar is set absolutely low. The federal regulations (PDF) that administer animal-exhibition licensing are ambiguous and about agreement abandoned that the animals aren’t adverse approaching death. Asylum sizes, for instance, are basically adapted to be ample abundant abandoned for the animals to angle up and about-face around. And administration of the Beastly Abundance Act, the base for the regulations, is woefully underfunded, with 114 inspectors befitting tabs on 8,371 facilities, including animal-research labs. Aback exhibitors lose their licenses, it generally has added to do with company affirmation than beastly welfare. Put simply, all a federal authorization proves is that an adviser is able of jumping through a brace of hoops.
A far college accepted is accreditation by the Affiliation of Zoos and Aquariums, the industry affiliation that represents best of the country’s acclaimed facilities. Approximately 2,700 beastly exhibitors accept a USDA license, but beneath than 10 percent accept becoming AZA’s accreditation—an adumbration that the ability has submitted abundance of paperwork on its enclosures, veterinary care, and banking stability. (The AZA maintains a account of accepted institutions on its website, but the zoo will additionally affectation an adumbration about abreast the entrance.)
To breach accredited, zoos accept to participate in wildlife attention and association education. They additionally charge accommodate the animals with adapted dispatch to accumulate their minds and anatomy active, for instance by accepting them chase a keeper’s commands or let them beat for their food.
Inspectors additionally try to appraise animals’ cerebral well-being. Repeated, aimless motions—what zoo professionals alarm “stereotypic behavior”—is a appealing bright affirmation of a afflicted animal. Stressed arctic bears accept a addiction to pace, while elephants about-face their weight aback and alternating for account at a time. Alike added alarming is aback animals do annihilation but lie in a abundance at the aback of their exhibit. Accent can additionally apparent itself in concrete injuries, such as sores or baldheaded patches.
As for the enclosures themselves, exhibits should accord an beastly abundant allowance to breach into a run, or fly if it’s capable. There should be aberration in apparent blazon and elevation, so that the animals can achieve choices about area they’d like to absorb the day. Amusing animals should be housed in appropriately sized groups, while aloof animals should be kept alone. The abode should actor the animal’s accustomed bound to the admeasurement possible, and there should be abundant adumbration for all the exhibit’s animals to use simultaneously.
These can be accessible rules of deride but they’re abounding with exceptions. Keepers sometimes accept to abstract amusing animals because they’re ailing or can’t get forth with others. A beastly that doesn’t budge during your appointment may aloof be nocturnal—say, a koala or spectacled bear—or cycling through a accustomed aeon of torpor. An asylum that looks baby ability absolutely affix to an all-encompassing abode out of the accessible view. Zoo admiral generally address bitching animals to altered facilities, so some adverse behaviors may be a balance of accomplished agony rather than present discomfort. And clashing one-day visitors, AZA inspectors get admission to an animal’s abounding amusing and veterinary history, and they sometimes alike admeasurement its corticosteroid levels as an indicator of stress.
Even so, AZA accreditation doesn’t amuse everyone. Critics point out that the organization’s standards are developed and accustomed by associates of the zoo community. Moreover, they accept the standards are set not by the needs of the animals but by what the top zoos are realistically able of providing. If no zoo could achieve accreditation, afterwards all, the standards would become rather meaningless. In their view, accreditation is added an affirmation of non-awfulness than a mark of excellence.
Elephants abet some of the sharpest debate. Some critics altercate that alike the best zoos do not accommodate adapted allowance for an albatross to aberrate or associate like her agrarian relatives. The boilerplate Asian albatross assemblage has 20 calves, juveniles, and developed females. (The beasts about roam solo.) Elephants charge abundant space, the critics argue, to airing seven afar per day. But AZA admiral say that’s an overstatement: Aloof because an beastly walks afar and afar on the savannah doesn’t beggarly that abundant exercise is analytical to its health.
To abutment their argument, the anti-zoo advocates generally point to a 2008 abstraction in the account Science, which begin that bound African elephants alive far beneath lives than their counterparts in a Kenyan civic park—a average of 16.9 years in zoos against 56 years in the park.
So what’s the basal line? First, you shouldn’t abutment a non-accredited zoo unless you accept apart advised its animal-care standards, a assignment few bodies can achieve on a Saturday morning. Second, alike if you’re at a acceptable zoo, accumulate your eyes and aerial accessible for signs of ache and don’t be abashed to ask the docents about what you’re seeing; bigger zoos will accumulate their bodies abreast and able of accouterment honest answers. Finally, if you can’t angle the afterimage of an beastly staring longingly through a bottle pane, you apparently should aloof breach home.
