The octopus has been heralded as the most intelligent invertebrate on the planet, and its use of tools is often improvised. The intelligence of dolphins is well-known, but since they have flippers instead of hands, many experts didn't think they used tools. This may be due to difference in the rewards gained by tool use: Gombe chimpanzees collect 760 ants/min compared to 180 ants/min for the Tai chimpanzees. [39], Orangutans (genus Pongo) were first observed using tools in the wild in 1994 in the northwest corner of Sumatra. The twigs were first modified by removing side twigs and leaves and then used such that the barbs helped drag prey out of tree crevices.[8]. The list of discoveries of animals using tools is ever […] [81][85] Sponging is heavily sex-biased to females. American crows are another of several species of birds that possess prey dropping behavior. On average, a kelp gull will descend at an average of 4 m/s in comparison to the prey’s fall of 5 m/s, which allows the gull to reach the ground about 0.5 seconds after the prey has landed onto the surface [111]. A 2018 study even revealed that crows can build compound tools, as crows observed by the researchers were able to attach small objects together to create a stick long enough to reach a food source. Dolphins appear to use the conch shells to scoop fish from the substrate then carry the shell to retrieve the fish near the surface. There were different styles of modification of the branches, the most common of which was holding the main stem with the front foot and pulling off a side branch or distal end with the trunk. [28] There are more limited reports of the closely related bonobo (Pan paniscus) using tools in the wild; it has been claimed they rarely use tools in the wild although they use tools as readily as chimpanzees when in captivity,[29] It has been reported that females of both chimpanzees and bonobos use tools more avidly than males. In this pouch (preferentially the left side), the animal stores collected food to bring to the surface. An otter regularly carries a stone around on its belly and uses it to pound open its mollusk meal. [14] Many other species of animals, both avian and non-avian, play with objects in a similar manner. This is the first account of chimpanzees using a pounding tool technology to break down large food items into bite-sized chunks rather than just extracting it from other unobtainable sources such as baobab nuts. The effects of prey characteristics and prey loss", "Avian prey-dropping behavior. This modification of a leafy twig into a tool was a major discovery: previously, scientists thought that only humans made and used tools, and that this was what separated humans from other animals. [53], There are few reports of gorillas using tools in the wild. [110], In observations made in Central Europe, a two-year-old black-headed gull was seen taking a small swan mussel about 60 feet up into the air to drop on an asphalt road. They often "decorate" themselves by covering their bodies with sedentary animals and plants like sea anemones and seaweed. Female chimps learn to fish for termites earlier and better than the young males. Brown-headed nuthatches (Sitta pusilla) have been observed to methodically use bark pieces to remove other flakes of bark from a tree. [26] Captive gorillas have made a variety of tools. [14], Corvids are a family of birds characterised by relatively large brains, remarkable behavioural plasticity (especially highly innovative foraging behaviour) and well-developed cognitive abilities. Inside are seeds that are highly desirable to the orangutans, but they are surrounded by fibreglass-like hairs that are painful if eaten. When disturbed, the parent acara often seize one end of the egg-carrying leaf in their mouth and drag it to deeper and safer locations.[152]. One possible explanation for the absence of observed tool use in wild gorillas is that they are less dependent on foraging techniques that require the use of tools, since they exploit food resources differently from chimpanzees. Aside from primates, crows show the most ingenuity in the animal kingdom. [112], The green heron (Butorides virescens) and its sister species the striated heron (Butorides striata) have been recorded using food (bread crusts), insects, leaves, and other small objects as bait to attract fish, which they then capture and eat. [57] In another group of captive gorillas, several individuals were observed throwing sticks and branches into a tree, apparently to knock down leaves and seeds. The use of tools by primates is varied and includes hunting (mammals, invertebrates, fish), collecting honey, processing food (nuts, fruits, vegetables and seeds), collecting water, weapons and shelter. Some pet owners may discover this firsthand when a trickster bird uses a piece of metal or plastic to lift open its cage lock. They then stiffen their legs and move away in a manner which has been called "stilt-walking". Chimpanzees in the Tai National Park only sometimes use tools, whereas Gombe chimpanzees rely almost exclusively on tools for their intake of driver ants. Some birds take advantage of human activity, such as carrion crows in Japan which drop nuts in front of cars to crack them open. [106], Captive individuals of the critically endangered Hawaiian crow (Corvus hawaiiensis) use tools to extract food from holes drilled in logs. [29], Research in 2007 showed that common chimpanzees sharpen sticks to use as weapons when hunting mammals.

Furthermore, the blanket octopus has been known to tear off tentacles from jellyfish and wield them as weapons when attacked. Both wild and captive elephants are known to create tools using their trunk and feet, mainly for swatting flies, scratching, plugging waterholes that they have dug (to close them up again so the water doesn't evaporate) and reaching food that is out of reach. Soon after her initial discovery of tool use, Goodall observed other chimpanzees picking up leafy twigs, stripping off the leaves and using the stems to fish for insects. [119][120], Other corvid species, such as rooks (Corvus frugilegus), can also make and use tools in the laboratory, showing a degree of sophistication similar to that of New Caledonian crows. Kelp gulls normally drop black mussels, and drop-sites are normally chosen based on how well it would break the prey as well as the amount of kleptoparasites that are in the area, as other gulls may take the opportunity to steal an individuals’ prey. Others, for example Lawick-Goodall,[6] distinguish between "tool use" and "object use".

Some of the abilities we’ve mentioned already might be considered innate skills, so the most fascinating question remains: is it possible for some animals to learn to use tools? Elephants are known for being very intelligent animals. [112], In 2009, two sooty gulls near Hamata, Egypt, were seen using prey-dropping behavior on a strip of coral reef. Captive New Caledonian crows have used stick tools to make first contact with objects that were novel and hence potentially dangerous, while other individuals have been observed using a tool when food was within reach but placed next to a model snake. [12], Smaller individuals of the common blanket octopus (Tremoctopus violaceus) hold the tentacles of the Portuguese man o' war, to whose poison they are immune, both as protection and as a method of capturing prey. [118], New Caledonian crows also demonstrate prey dropping behavior The first recorded evidence of this species of crow demonstrating prey dropping behavior on the snail Placostylus fibratus in a 2013 study. [160] It was in 1975 that scientists first observed Oecanthus burmeisteri [sv] and two other species of South African chirping crickets doing this.
