Researchers at a nature to reserve in conquered the Czech Republic photos of a wild boar frees two younger captive pigs in a trap, the first when they say something like that behavior is documented in the animals.
The incident, reported in the news Nature, happened in the Voděradské Bučiny National Nature Reserve east of Prague in January 2020.
Last research has suggested the intelligence of pigs. The wild boar escape plan, the researchers wrote, “was fast and certain behaviors were complex and precisely targeted, indicating profound prosocial tendencies and exceptional problem-solving power in wild boar.”
Researchers regularly catch wild boars in the reserve using box cages, die are monitored with remote camera’s. They then do an ear tag and a GPS collar on the animals. Two young wild boars are caught in the fall, die maize as bait. Once in the cage, the swine triggered a wire die the doors close and two wooden blocks drop to secure the fall.
The captive bears were in the fall for about two hours as the other boars approached the trap, based on on pictures taken automatically every two minutes.
In the rescue attempt, die took about 29 minutes, an adult female wild boar and five other boars began to touch the tree trunk die held the front door with their snouts. The female boar first loaded the log with her head, release one end of the log and then went to the log from the back door. While there is no picture of the female boar that manipulated that log was freed by the next photo. AN final photo shows an empty trap with the front door also ajar.
“When She Wasn’t Successful” with the first log, she tried the . to delete second log,” the researchers wrote. “After deleting the logs, she took care of the… side of the door. Her behavior helped the trapped conspecifics die could open the door from the inside.”
since the photos didn’t capture all of the rescue, some of the other wild boar could have teamed up up with the adult female boar who took the lead on freeing the captured, the researchers say.
“It is possible that they could have also been involved in saving the captive swine and that the rescue was, in factcooperative,” they wrote. “Cooperative rescue behavior would not be surprising because of the frequent cooperative interactions and close social bonds in swine.”
Other species have been documented die show rescue behavior, which is a rarity sign of complex thoughts including empathy and social actions, the researchers note. In studies, dogs have opened a door to free their trapped owners in An box. Having lab rats also other trapped rats freed in a tube and ants saved co-caught ants in bury a nylon bow in sand.
