Barbara Smuts, a renowned primatologist at the University of Michigan, recently distributed a petition asking that the other gorillas at the Cincinnati Zoo be relocated to a sanctuary far from the ogling, screeching crowds of their clothed relations.
Researchers also disagree on whether we should continue breeding apes in captivity, and if so, to what end.
Others deride most zoos as little more than amusement parks with educational placards that few people bother to read.
“There’s no good evidence that captive apes are having any positive effect on their wild relatives,” said Marc Bekoff, a behavioral ecologist and professor emeritus at the University of Colorado.
Peter Singer, a bioethicist at Princeton University, said, “Our primary concern ought to be the well-being of gorillas, but zoos are constructed the other way around: The primary concern is that humans can see the gorillas.”
Innate curiosity, researchers suggest, may explain some of Harambe’s behavior seen on the video of his fatal encounter with the boy who fell into his enclosure. He tried pulling the boy into a grotto, perhaps to protect him or to claim the fascinating new playmate for himself.
But with the mounting commotion and screams from the onlookers above, researchers said, Harambe grew agitated and soon assumed the stance of a male silverback in dominance display mode.
“It’s what we used to call strutting, and male gorillas do it all the time,” Dr. Watts said. “A silverback will stand or walk around with arms and legs stiffly extended, his hair piloerect, to make himself look bigger and more impressive. Harambe was definitely doing that when he was standing over the boy.”
The behavior is mostly bluster: If Harambe had been intent on killing the boy, Dr. Hrdy said, as an interloping male gorilla might kill the babies sired by the silverback he just deposed — the quicker to claim the resident females for himself — “he would have done it in seconds,” probably with a stereotypical bite to the skull.
Nevertheless, the strut introduced risks of its own, particularly when Harambe began dragging the boy around the enclosure, as a displaying gorilla will sometimes drag around a large branch.
Dr. Watts, who said he had been “punched, knocked over and dragged” by male gorillas but never seriously injured, wishes he had been at the Cincinnati Zoo as the crisis unfolded. He would have volunteered to enter the enclosure.
