Researchers from the University of York and the University of St. Andrews in the United Kingdom observed greater vasa parrots (Coracopsis vasa) using pebbles and date pits to extract a fine calcium powder from seashells that they would then lick off the shell. Their observations were published in Biology Letters. The birds were in essence creating their own nutritional supplements from materials readily available in their cages. While parrots are known to use their beaks to extract calcium from shells, this study shows the first known example of them using tools to accomplish the task.…
A research team led by Julian Finn of the Museum of Victoria in Melbourne has discovered octopuses using coconut shells as portable protection. Not only do they hide under single halves but will actually pull two halves together and hide inside, like some sort of Super Mario baddie. The video is remarkable.
Using tools means octopuses now join an elite club of wise animals including chimps, dolphins, and Tim Allen.

In martial arts classes, students are often taught to treat weapons as extensions of their own body. But this is more than just a metaphor. It turns out that when we use tools - not just swords and spears, but toothbrushes and rakes as well - our brain treats them as temporary body parts.
According to some psychologists, our brains rely on a mental representation of our bodies called the "body schema", which allows us to coordinate our various parts and to interact with the world around us. Now, Lucilla Cardinali from INSERM, France has found that we incorporate tools into this mental plan…
What the heck has this world come to? All over the internet, this picture of an Orangutan trying to fish with a stick has been shown:
But what's the story behind this? Is this evidence that humans are not unique among the Great Apes as tool-users?
Not quite. According to the Daily Mail, this is an orangutan that had extensive exposure to humans; this jungle setting is actually where they reintroduce orangutans into the wild from zoos, private homes and (yikes) butcher shops. This particular orangutan actually doesn't successfully know how to fish; this was something he copied from nearby…
