Can't say I know a whole lot about this, but I do know that in Britain there have been reports of crows starting fire in hay barns by picking up cigarette buds that were still burning and drop them into the hay. Researchers have shown that you can train the birds to do certain behaviors and that these birds could actually somehow teach other birds these behaviors. I got this off of a program on the discovery channel a few years back. Aside from this, I don't know much else about it.
