I have owned a small Myers Parrot for about ten years.<p>He is very clever in understanding his environment. Once he raised one wing over his head and lowered the other wing to make his shoulders narrow enough to walk between two obstacles. He also has a strange desire to explore dark closets - odd since he has poor night vision.<p>I advise against anyone buying a Parrot unless they have a lot of free time. A Parrot will thrive in captivity if he has a lot (a lot!) of attention, otherwise Parrots in captivity will be miserable. For example, my wife and I need to keep our bird in the same room where we are hanging out - it does not do at all to leave a Parrot by themselves and we only do so when we go out to some social event. When we travel I hire a bird specialist to care for him. I have mostly been retired for a long time, so he is a good pet for me.
What I'd be interested in would be the question if he hides his tool or what happens to the tool after he gets the nut. Is there any sort of reuse or does he build a new tool each time.<p>Would he recognize premade tools, maybe pick the best one from a collection of tools present?<p>There's also some potential in seeing if birds exibit certain types of economic behaviour. If it would be somewhat tedious to collect two nuts per day and he could live off one, would he save some nuts to build a more complex tool (requireing a day+ of build time) that would allow him to harvest a "free" nut each day etc.
Somewhat related is the crow machine. It trains crows to collect and deposit money in exchange for a treat: <a href="http://www.josh.is/crow-machine/" rel="nofollow">http://www.josh.is/crow-machine/</a>
Before it was only the chimps and other apes, and now dolphins, then the parrots ... we have to step up our game people! Next thing you know they are submitting pull requests ...
My favorite example of tool use in birds is this video <a href="http://www.youtube.com/watch?v=OYZnsO2ZgWo" rel="nofollow">http://www.youtube.com/watch?v=OYZnsO2ZgWo</a> of a crow that actually bends a piece of wire to form a hook. There are some details about it here: <a href="http://news.nationalgeographic.com/news/2002/08/0808_020808_crow.html" rel="nofollow">http://news.nationalgeographic.com/news/2002/08/0808_020808_...</a>
What I wonder is: why is this so relevant if birds have been building nests for quite a while yet? I do not get the great difference... And please do not mention the 'tool' word: a nest is something MUCH more complicated and abstract than a tool.
Ever heard of Anthropocentrism? Why would tool use be confined to humans? When a baby (or a cub) learns to control his/her eye muscles, or her/his hands; when a bird builds a nest, it's tool use. Tool use is simply an extension of learning how to use our bodily organs, nothing special about it, all living creatures do that.
