I think this is what you're getting at, but the really interesting question regarding corvid intelligence (in my opinion) is whether their pallium implements the same or similar computations and uses the same or similar representations as mammalian neocortex. Clearly because of the different evolutionary origin there are structural/architectural differences (eg pallium is nucleated rather than laminated), but maybe there is only a single computational "solution" to the problem of general intelligence. To pose it as a question: does avian pallium solve problems in similar ways/using similar algorithms as mammalian cortex or did its early divergence allow it to find different solutions? I think the answer to this, whichever way it breaks, will have pretty big implications for AI generally. Same story goes for Cephalopods.
