When Visitors Stay for Minutes, But Captivity Can Last a Lifetime
Born Free USA has released its latest investigation into the U.S. zoo industry—this time examining the San Francisco Zoo. Its findings raise important questions about animal welfare, education and what captivity is ultimately supposed to accomplish.
Born Free USA investigators visited the zoo in August 2025 as part of a larger project examining animal welfare, conservation and education at ten of the country’s highest-ranking zoos.
One finding immediately stands out: the average time visitors spent viewing the animal exhibits studied was just 2 minutes and 17 seconds. For chimpanzees, the contrast was even more striking. During a ten-minute observation period, only seven people stopped to look at them, spending an average of just 11 seconds at the exhibit.
Those numbers matter because education and conservation are routinely presented as central justifications for keeping wild animals in zoos. If visitors spend only seconds or minutes actually observing those animals, an important question follows: What meaningful understanding of wildlife is being created during that brief encounter?
Visitor engagement, however, was only part of what investigators documented.
At the wolf enclosure, Born Free reported that one wolf repeatedly paced the same route throughout an entire ten-minute observation period. Children ran alongside the animal laughing, while an adult reportedly interpreted the behavior as “cute.” Investigators instead characterized the repetitive pacing as an indicator of severe stress—an extraordinary example of how abnormal captive behavior can be interpreted by visitors as entertainment rather than a potential welfare concern.
Elsewhere, investigators documented birds whose wings had been pinioned, a two-toed sloth sleeping in a small carrier in what they described as a bright and loud environment, and a rhinoceros whose horn had been worn completely flat. Zoo signage confirmed that the rhino had worn down his horn through repeated rubbing against parts of his enclosure.
The investigation also arrives against a backdrop of broader concerns about the facility. Born Free cites previous criticism from the San Francisco Animal Control and Welfare Commission describing outdated enclosures and characterizing the zoo as “dilapidated” and unsafe for animals and visitors. The report also cites a 2026 poll in which 76% of San Franciscans surveyed said they wanted the zoo “reimagined.”
Perhaps the most powerful contrast in this investigation is therefore also the simplest:
For the visitor, the encounter may last 11 seconds, a minute, or two. For the animal, captivity may last a lifetime.
That doesn’t mean we should stop asking whether zoos can contribute to conservation, education or animal welfare. It means those claims deserve to be measured against what actually happens—to the animals, to the visitors and to conservation in the wild.
Good conservation should withstand scrutiny, and good animal welfare should welcome accountability.
Independent investigations like this matter because they give the public an opportunity to look beyond the exhibit—and ask whether what we are being told about captivity is supported by what we can actually observe.
