Have you ever encountered a parrot that could talk? Have you ever tried to make them repeat what you say? But have you thought why parrots can do that but not other animals?
On the inside, the brains are arranged very similarly. Though it doesn't say, the purple part of the brain is the hearing and speaking. As you can see, it's pretty close in area.
-According to Duke University, "Parrots are one of the few animals considered ‘vocal learners,’ meaning they can imitate sounds." -And they found "the average bird's brain had twice as many brain cells per gram as the average mammal."
