Figaro (shown above) was observed by a student using a piece of bamboo to try to retrieve a dropped pebble. This was the first documented evidence of a Goffin’s cockatoo attempting to use a tool so the researchers decided to try a little experiment. They placed a cashew just outside of Figaro’s cage and observed as Figaro attempted to retrieve it using a stick he found on the floor of the aviary. When that was unsuccessful, he broke a splinter off of a wooden beam and was able to successfully retrieve the nut. The researchers were impressed by not only his ability to use tools, but also to make them.
