Parrots are a rotten analogy -- parrots are very smart, in a number of
complex ways, probably the most intelligent extant birds.
Bakker's 'giant ground running hawks and eagles' is, I think, a limited
analogy, due to relative prey sizes -- better for large tyrannosaurs
than for small maniraptorans. For things like oviraptosaurs, ratites
might be rather *good* analogies.

Keep in mind that most carnivores aren't smart; they have good reflexes.
It's generally the omnivores that are smart. (more varied situations to
deal with, and more benefit from trying new things.)
To maintain the end is to uphold the means.
