Let's remember: for fossil taxa, EQ is *ALL* we are ever going to have in order 
to estimate intelligence. We cannot do the sort of
behavioral experiments that were done by the workers on modern birds.

That being said, I don't recall in the press releases about Lefebvre's work 
whether they ever scaled the "Avian IQ" measures against
EQ of the birds.
