Recently, Alice Auersperg and colleagues at the University of Vienna, Austria, observed a caged cockatoo named Figaro. The bird was unable to reach a nut that fell outside his cage.
No worries. There was a large piece of wood on the cage floor. Figaro used his beak to cut a splinter. Using it, he was able to retrieve the nut.
It seems that animals are clever and innovative because they were created to be clever.
