After an Earthquake, These Elephants Knew Exactly Who to Follow: Mom
A video from the San Diego Zoo taken during an earthquake put complex elephant herd dynamics on display.A tremor from a 5.2-magnitude earthquake that struck about 60 miles away prompted a herd of elephants at the San Diego Zoo to form a tight circle to protect the calves.San Diego Zoo Wildlife Alliance, via Associated PressThe 5.2 magnitude earthquake that shook Southern California on Monday may have provoked a collective shrug from humans in the region, but a few elephants in San Diego took the tremor very seriously.A video taken at the San Diego Zoo shows the action unfold: Five African elephants are basking in the morning sun until the camera begins to shake and a tremor sends the animals scrambling toward one another.A few moments later, almost in unison, the elephants form a tight circle, with the older elephants surrounding the younger calves. The herd remains in formation through the end of the video, facing outward with ears extended, as if on high alert for threats.The earthquake, which struck around 10 a.m. on Monday, had its epicenter near Julian, Calif., about 60 miles northeast of San Diego. There were no reports of injuries or damage, according to the San Diego County Sheriff’s Office.The response from the elephants was a defensive position known as “bunching,” and is a typical reaction to threats, said Joyce Poole, a conservation biologist with a doctorate in elephant behavior from Cambridge University. “They feel more secure when they are close together,” she said.When bunched, elephants often have their tusks pointed out, ears extended, eyes opened wide and trunks out, trying to smell potential threats. The formation, “like the spokes of a wheel,” Dr. Poole said, gives the group a 360-degree view of their surroundings to pinpoint any danger. The younger members instinctively seek out the most protected position inside the circle, she said.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
