Brown Bears and Other Animals that Use Tools

By on
  • Chimpanzees
    Dr. Jane Goodall first observed chimps using tools in 1960 when she saw the animal using sticks as probes to collect termites. In 2007, researchers in Fongoli, Senegal saw chimps sharpen branches and spear smaller primates called bush babies. Researchers saw this happen 22 times. In one instance, the chimp successfully killed and ate a bush baby that it speared. It is the only evidence of a non-human species using weapons. Reuters
  • New Caledonian Crow
    The New Caledonian Crow, which lives only on the Island of New Caledonia in the South Pacific, uses sticks to dig for food similar to the way chimps do. The bird will break and sharpen twigs and use it to poke and agitate grubs living in a log into biting the stick. The crow then withdraws the grub and eats it. Reuters
  • Capuchin Monkeys
    Capuchins are very intelligent monkeys and are frequently used in lab tests. In the wild, researchers have observed the monkey using stones as heavy as the monkey themselves to crack open hard, brittle nuts to get to the fruit. Younger monkeys will learn the process from older, more experienced adults. Reuters
  • Sea Otters
    Much like the Capuchin, sea otters will use rocks to crack open clam and abalone shells. Otters can hammer as fast as 180 times per minute to crack stubborn shells. Reuters
  • Orangutans
    Orangutans make a noise called a “kiss squeak” to warn other members of the species of a predator such as a leopard. However, researchers observed the ape using a branch and leaves to manipulate kiss squeak and make it sound deeper – the only known case of an animal manipulating sound. "It looks like orangutans try to deceive the predator when using the kiss squeaks on leaves, because orangutans only use it when they're highly distressed," Madeleine Hardus, the primatologist who discovered the ape using the technique, told New Scientist.

  • Elephants
    Researchers have observed elephants using a variety of different tools. The animal uses its trunk to pick up long sticks to scratch itself or palm fronds to swat flies. Elephants also intentionally drop rocks and logs onto electric fences in order to break it and escape from captivity. Reuters
  • Patna to Become Asia’s First Dolphin Research Centre
    Dolphins living in areas with sandy bottoms will sometimes place a marine sponge on their nose to protect it from scratches when digging for fish. Female dolphins teach the technique to their daughters. Reuters

Animals may not carry an electric drill or a screwdriver but that doesn't mean they don't know how to use tools. Researchers have seen primates, elephants, birds and other animals use tools both in the wild and in captivity to hunt, protect themselves or get rid of pests.

Most recently, researchers discovered that brown bears use tools to scratch and groom themselves. Click through the slideshow to see other tool-using animals.
