We very strongly believe they don't grok recursion because they don't use it. We have countless hours of recordings of dolphins, parrots, whales etc... communicating and none of the vocal patterns are complex enough to indicate recursion. Recursion implies the ability to create infinitely complex language constructs--if animals have this capability they are communicating via some method that we aren't capable of recording, or they've just decided not to do it when we're listening. You might as well say that mice are more intelligent than humans, they just do a good job of hiding--sure I can't prove that you're wrong, but I wouldn't bet much money on it.
