Godzilla bird brain

“Through the equipment on the harpoon you fired, we learned much about Godzilla’s physical nature,” the scientist said.  “We managed to get an EEG.  That is a reading of Godzilla’s brain waves.  We learned that Godzilla’s brain is very similar to a modern bird’s brain--though vastly larger, of course.”
“You see son,” Admiral Willis spoke up.  “Dr. Nobeyama believes that Godzilla may respond to the same sounds that a bird responds to.  And that’s good news for us!”
