Parrot banned from football ground for imitating referee's whistle

This is the story of a parrot who started mimicking the refs whistle and causing chaos.

But I have one question: who would let someone in to a soccer game with a caged parrot? Why would you want to bring a parrot? What the WTF?

If this was the lady's goal, ie. to cause havoc on the field, then why didn't she just bring a whistle and do it herself? Was it supposed to be a mascot? Good luck?

So many questions.
