All in Animal Behavior
Gorillas are social animals that live in troops, typically headed by a dominant male, along with several adult females and their offspring. Often a female will leave the troop and relocate – a behavior primatologists call “dispersal.” New research shows that the females tend to seek out other females they already know when they join a new troop, upending a long held view that the males are running the show.
A man in Karnataka, India thought it might be fun to take a selfie with a wild elephant off the roadway in the Bandipur Tiger Reserve. It was not. He didn’t get the selfie, but he did get run down by the startled creature and was nearly stomped to death. Plus he lost his pants, briefly.
Marine scientists who study orcas have been busy. They’ve seen the killer whales wearing fish as a fashion statement, using kelp to exfoliate, and of course harassing yachtsmen, just to be jerks. Now comes news that the apex predators are engaging in more altruistic behavior: they’re bringing us gifts.
Each spring, billions of brown moths fly more than 600 miles in southeastern Australia to escape summer heat, to a small clutch of cool caves located in the Australian Alps. They find their way by using the stars, then return to their breeding grounds in the autumn to reproduce, then they die.
Marine biologists in the north Pacific have observed orcas taking the killer whale version of a spa day: using kelp to massage each other. The behavior, which involves fashioning a tubular piece of seaweed and using it for a planned purpose, marks the first time a marine animal has been seen using tools.
The first, and perhaps only, corgi to become a canine cop is based in Weifang, Shandong province in eastern China. The 1 ½ year old short-legged dog named Fuzai will do anything for food treats, for good or ill.
In mammalian social groups males tend to dominate, but among one of our closest relatives – the bonobo – it’s females who have the upper hand. Primatologists believe the ladies get and maintain power with a simple tactic: they work together.
Wild chimpanzees drum with rhythm, according to a new study by primatologists from the University of St Andrews. Not only that, chimps from either side of Africa have their own distinct beats.
