Say this guy on my visit last weekend.
If I remember correctly, this hawk's name is Shriek. He was being carried around by a trainer. When a lot of people gathered around, he started explaining some of the animals history.
He's around 15 years old, I think, and used mainly for educational purposes. He's also a rescue, having been hit by a car years ago.
Couldn't catch most of what he was saying, as I was focusing on getting shot and returning a lost iPhone.
