Don't know how they filmed this, any ideas JW?

I'm surprised that the hawk would destroy the nest. I would have thought out of sight, out of mind

I was cheering for the hawk.. I think that animals have been and are evolving to use deductive reasoning. That's an example of it and there are other examples of animals being able to use reasoning.

I am not surprised at all that the bird would learn to hit a drey.  These birds are rewarded for learning, whether they are working with a falconer or on their own hook.  The act of hunting prey involves problem solving, recognition of patterns, and using deductive reasoning to make those wild leaps of logic. 

And the squirrel is constantly learning new methods of escape, too. 

In both cases, winners get to breed, ensuring offspring are faster, smarter, better, stronger, etc.
