pinning: a sign for speech

I was hunting for new birds at a pet shop center(lots of shops in one place) here in riyadh and found many IRN's for sale. all are green though! there was one shop owner I was haggling with coz he had 4 fids (2 males and 2 females - all green) and he had different prices for each. though a bit difficult to communicate, I asked him why the difference in prices. He then showed me that when a bird's eye pins/dillates (meaning the white pupils are moving when it opens its beak) it is indicative that it can be trained to talk. I think he was saying this thru experience. Can anybody support this claim/ theory?
