A large parrot's scream? I ask because I already have an amazon who screams like a cockatoo, and my childhood was spent with a cockatoo in the house. I'm wondering if a rooster is something that's actually going to startle me, or if I should expect pretty smooth sailing since my ears are already battered from bird screeches. And if you don't know, compare the volume of a rooster crowing to something (anything) else. Not because it's important, mind, but because I'm really curious.
