Are you sure it wasn't the African gray?? That is the parrot species that
has been induced to produce the most spectacular feats of reasoning.

Some of what the African gray can do is pretty hard to lay entirely to
memory.  It requires, at the very least, a fairly sophisticated form of
conceptual discrimination.

But the African gray is considered about the smartest bird alive today, and
is hardly a good analog for any other archosaur. (And parrots in general
are among the most intelligent of birds).
