Born Free Honolulu Zoo Investigation:
Born Free USA has released a new 32-page investigation of the Honolulu Zoo, an Association of Zoos and Aquariums (AZA)-accredited facility.

Investigators visited in September 2025 as part of a broader examination of leading U.S. zoos, evaluating three of the industry’s central claims: animal welfare, education and conservation.

What they documented raises difficult questions.

Among the report’s observations:

• A king vulture exhibited repetitive preening and head-rolling that investigators described as possible stereotypic behavior.

• Investigators documented worn pacing paths in tiger enclosures and deep pacing paths around the cheetah enclosure. The zoo’s three cheetahs are involved in an AZA Species Survival Plan, yet offspring produced through the program are not intended for release into the wild. 

• Orangutans Rusti and Violet, both longtime zoo residents, were housed separately after aggression reportedly made keeping them together unsafe. Investigators noted that only one could access most of the larger outdoor space and enrichment at a time. 

• The Asian elephants’ enclosure was described as having packed dirt and rock substrate, with limited observed opportunities to approximate the extensive foraging behavior that occupies much of a wild elephant’s day.

The investigation also examined the claim that zoos provide meaningful public education.

Across the rhino, elephant, orangutan, cheetah and lion exhibits studied, visitors spent an average of just 52 seconds at each exhibit. At the elephant and rhino exhibits, no visitor observed remained longer than one minute.

How much meaningful conservation education can occur in less than a minute?

Importantly, Born Free also acknowledges genuine conservation accomplishments at Honolulu Zoo—particularly its work helping rescue, rehabilitate and release native Hawaiian wildlife, including historic efforts associated with recovery of the nēnē. 

And perhaps that highlights the most important distinction:

Protecting wildlife with the goal of recovery and return to the wild is very different from breeding animals who will remain in captivity for life.

Born Free concludes that while Honolulu Zoo conducts some meaningful conservation work, its investigation still found a conflict between providing experiences for human visitors and meeting the behavioral and welfare needs of captive wild animals. 

This isn’t a roadside zoo.

It is an AZA-accredited zoo.

That makes the larger question especially important:

If even institutions promoted as models of modern zoo care face these limitations, should the conversation be only about improving captivity—or also about finding better ways to protect wildlife in the wild?
