I think my Goffin, set loose in a nut and bolt factory, would think he had gone to Cockatoo Heaven. He has a beak that he uses to snip bailing wire that I use to thwart him (temporarily) from opening cage doors and throwing all of the food dishes, water dishes, hanging toys and perches out the door. He has develped the skill of unscrewing food jars with their four-inch diameter lids and I watched him and another Cockatoo (a Parasol) work together for hours figuring out how to pop off the lid to a ginger jar that contained my cleaning rags. How they succeeded, I didn't have the patience to find out, but all of my cleaning cloths were shredded on the floor the next day and the three pound ginger jar was on its side, wide open, with the once secure lid shattered on the floor. I wish I could have seen their victory dance after that one! High fours all around, I guess.
