Honey badgers both wild and captive have been filmed manipulating various objects to assist them in making climbs, including making mud balls and stacking them. In long-tailed macaques, tool use has been extensively observed, particularly within foraging and grooming habits. These tools have both been synthetic and organic in origin and their use varies greatly depending on populations. The research done within these populations and their tool use has been used to draw conclusions that high levels of sensorimotor intelligence help evolve innovative tool use.
- Most tellingly, if the spine or twig isn’t exactly the right shape, the woodpecker finch will fashion this tool to suit its purposes, which seems to involve learning by trial and error.
- Several species of wrasses have been observed using rocks as anvils to crack bivalve shells.
- Its origin could be related to the throwing of eggs; rounded (egg-like) stones are preferred to jagged ones.
- Crows recognize human faces, communicate complex concepts with other crows, and think about the future.
- Gorillas, like chimpanzees, have been seen using sticks to catch bugs like termites and ants.
As 104 of the 109 surviving members of the species were tested, it is believed to be a species-wide ability. Carrion crows were observed on Eden estuary in Scotland between February and March 1988 to investigate their dropping strategies with mussels. Carrion crows selected larger mussels and dropped them from a height of ~8m onto hard substrate. The height of mussels dropped were lower than what researchers expected, which may be due to difficulty locating prey post dropping as well as trying to prevent kleptoparasitism .
Animals That Use Tools This Is Amazing!
This behaviour, first reported in 1966, seems to be largely innate and is displayed by naïve individuals. Its origin could be related to the throwing of eggs; rounded (egg-like) stones are preferred to jagged ones. Various corvids have små hunder hunder til salgs reached for stones to place in a vessel of water so as to raise the surface level to drink from it or access a floating treat, enacting Aesop’s Fable of The Crow and the Pitcher. A family of captive Visayan warty pigs have been observed using a flat piece of bark as a digging tool. Molting brown bears in Alaska have been observed using rocks to exfoliate. There is also evidence that polar bears throw rocks and big pieces of ice to walruses to kill them.
When threatened by predators, they close the shells over themselves to hide, building a sort of protective armor. Furthermore, the blanket octopus has been known to tear off tentacles from jellyfish and wield them as weapons when attacked. The intelligence of dolphins is well-known, but since they have flippers instead of hands, many experts didn’t think they used tools. At least not until 1984, when bottlenose dolphins in Australia were seen tearing off pieces of sponge and wrapping them around their noses, apparently to prevent abrasions while they hunted on the sea floor. This behavior is believed to be handed down matrilineally, from mothers to daughters.
Once the stitch is made, the fibres fluff out on the outside and in effect they are more like rivets. Sometimes the fibres from one rivet are extended into an adjoining puncture and appear more like sewing. There are many variations in the nest and some may altogether lack the cradle of leaves. It is believed that only the female performs this sewing behaviour. The Latin binomial name of the common tailorbird, Orthotomus sutorius, means « straight-edged » « cobbler » rather than tailor.
Of The Smartest Animals On Earth
The scientists suspect that Priscilla may have learned how to use the tool herself, and passed on that knowledge to her mate and offspring. Chimpanzees are some of the closest relatives that humans have. They have a number of physical similarities with humans, and they behave in some of the same ways that humans do too.

When play is discussed in relation to manipulating objects, it is often used in association with the word « tool ». Some birds, notably crows, parrots and birds of prey, « play » with objects, many of them playing in flight with such items as stones, sticks and leaves, by letting them go and catching them again before they reach the ground. A few species repeatedly drop stones, apparently for the enjoyment of the sound effects.
A study in 2017 showed that bumblebees of the species Bombus terrestris learned to move a small wooden ball to the goal in order to get sucrose reward. In 2009, two sooty gulls near Hamata, Egypt, were seen using prey-dropping behavior on a strip of coral reef. Unlike other gulls, the gulls only flew up about 6 m and broke molluscs in one drop. In a small population in Bulgaria, Egyptian vultures use twigs to collect sheep wool for padding their nests. Although both twigs and wool can serve as nesting material, this appears to be deliberate tool use. The birds approached bits of discarded wool with a twig in their beak, which was then either used as a rake, to gather the wool into heaps, or to roll up the wool.
According to Jones and Kamil’s definition, a bearded vulture dropping a bone on a rock would not be considered using a tool since the rock cannot be seen as an extension of the body. However, the use of a rock manipulated using the beak to crack an ostrich egg would qualify the Egyptian vulture as a tool user. Many other species, including parrots, corvids and a range of passerines, have been noted as tool users. There is evidence that both ecological and cultural factors predict which dolphins use sponges as tools.
It’s reasonable to assume they have the same goals – magpies aren’t known for being exceptionally more thirsty than other birds – so we are seeing a cognitive ability in one species that is lacking in another. We think we’re pretty smart, with our knives and forks, but there are some clever creatures out there that use inanimate objects to help get their food in their tummies. Here are five extraordinary animals using tools to dig out their dinner. Archerfish are found in the tropical mangrove swamps of India and Australasia. They approach the surface, take aim at insects that sit on plants above the surface, squirt a jet of water at them, and grab them after the insects have been knocked off into the water.
