He has some fear based aggression issues, and is terrified of hands and sudden movements. He was terribly "cage aggressive", and would bite anyone and anything if given the chance. He did quite a bit of damage to a co-worker's hand, among other things, and would give no warning signs prior to biting.
He's come a long way in the last two months: He at a seed-only diet when he first came to me, and has since been switched over to a high quality pellet, mash, and fresh food diet. He's come to trust me enough to let me scritch his face and head while perched on my hand, though he won't allow anyone else anywhere near him, and he's finally playing with toys.
The problem I'm now facing is what seems to be excessive vocalization. Being that I have very little hands-on experience with this particular species, I'm basing this entirely on what I've been told by others.
I expect all birds to vocalize a bit first thing in the morning, just before bed, and here and there throughout the day, but he makes a high-pitched whiney/crying sound for hours on end throughout the day - he does it while he's eating, he does it while he's preening, he does it while he's playing with a toy; in the cage, out of the cage, and on the play stands. He does it when I'm prepping meals, when the dogs are out, when I'm out of sight and sometimes when I'm in his field of vision. He does it more when my significant other is in the room and I am not, but still does it even when my SO isn't there. He doesn't do it constantly, but it's pretty close to it. The only time he doesn't do it is when he's talking to me, the dogs, or the other bird, or when he's playing in a towel or blanket, in which case he's babbling to himself.
Now, I'm not so much concerned about how to stop this behavior if it is, indeed, excessive vocalization. I'm more concerned with whether or not it actually is excessive, and if it is, with why he's doing it. He is absolutely NOT reinforced for this behavior - we ignore him completely when he's doing it, as does our other bird and the other animals in the house. He will offer a whistle as a contact call if I whistle first, and since he does it whether I'm in the room or not, I don't think it's a contact call thing.
Is this normal for a Hahns, or is this just something he's learned to do to amuse himself?
