What is the principle of ghost bird fortune telling? A parrot took out your birthday card.

That is a trained parrot. The owner gave a signal and it took out the card!

360 days, 360 birthdays, can the parrot choose your birthday card from them?

It will take people half a day to find it. This cow x!

But I don't believe it! I admire bird training!
