Primates use and create tools in order to accomplish given tasks, they are able to make use of tools in a "human" manner.
“Many species have been observed to use tools in the wild, including, sea otters, herons, Egyptian vultures, woodpecker finches, capuchin monkeys.”
“However, only New Caledonian crows, and woodpecker finches habitually use and manufacture tools in the wild.”
Recent discoveries have shown that hundreds of animal species use tools. New Caledonia crows, for instance, use twigs to remove insect larvae from the inside of the insects nest.
Sea otters use flat stones to break open urchin shells, Sea otters place a sea urchin on their bellies as they float on their backs and using a rock, they break the shell so they can eat the inside of the urchin (1)
The Woodpecker Finch, and some herons can manufacture tools. “Herons in southern Japan have been observed using insects, berries, twigs, and discarded crackers as bait to catch prey, like a human fisherman, the heron will cast the bait in the water, then crouch down and wait for the curious or hungry fish that comes to inspect the lure. The birds have even been seen to trim oversized twigs to the proper dimensions.”
There have been 39 cases of true tool use in birds, New Caledonian crows modify and use tools to extract grubs from small holes and have even made hooks out of straight pieces of wire to get food.
“When given a worm suspended on an out-of-reach platform only accessible by collapsing the platform, 5 rooks dropped a stone down a vertical tube providing the necessary force to collapse the platform and acquire the worm by either nudging the stone into the tube or by observing another bird solve the task.
