It’s beak was never meant for such a task, so, he resorts to using both beak and claws to work the rod until finally figuring out a way to push it through the hole and then to shove it at the food. You can’t help but wonder how some of us human beings would have done under similar circumstances. The box was constructed of clear see-through plastic and had four walls, each of which had a means of allowing access to a bit of food mounted on a pedestal in the center of the box. The first method, and the one that all the birds tested found the easiest, was a string protruding from a wall that was tied to the food; pulling on it resulted in the food being yanked off its platform and rolling downhill and out of the box. The next wall consisted of a hole with a tube leading downhill to the food; pushing a marble through the hole caused it to roll downhill knocking off the food. The next wall consisted of nothing but a hole in the wall, which meant to get the food treat, the birds had to shove a wooden rod through the hole to knock it off its pedestal. And lastly, the fourth wall had a window that could be opened outward by use of a hook, thus allowing access to the inside of the box and the treat.
