There are play biting and excited biting and aggressive biting and frustration biting ( associated with puberty, mostly).
Play biting is when you 2 are wresting with him on his back, maybe you are tickling him. These are lite nips, not hard, but can get harder as the bird becomes more excited. take a break, let him cool down
Excited biting can be overstimulated play biting, just so happy to see you biting, hurry up with my food, man biting. Sometimes a break is indicated , sometimes you need to hustle the food up and just not give opportunity to bite.
Aggressive biting - in a well adjusted parrot, you shouldnt see too much aggressive biting. Usually indicates that something else is driving it, and it is never the fault of the parrot. This is hard to figure out - what are you doing wrong, what have you not thought of that is irritating him. THe board can really help with this one, there is so much experience on here, that most situations have already been experienced.
Puberty or hormonal driven biting - you have time on this one, since this can develope when puberty arrives and the hormones kick in. Some feel it a LOT, some you hardly notice it, and each bird is different, even within a species. Again, this board is your friend for this type of biting.
But the easiest bite to work on is the one that you avoid. Learn your parrots body language, his eyes, his stance, his mannerisms, his schedule. Does he like to be touched on his beak? When? How hard? How about scratches? Example - Salty likes a scratch but it is when he wants it , not me. He likes them late in the day, after dinner, mostly. Can I entice him at other times? Yes, but I risk getting a nip to tell me "No Thanks". Can you tell when your boy has had enough? Some one once told me to always stop scratches and cuddles before the parrot has had enough, ie, he stops before you do. If you let him tell you when he's had enough, you risk a nip or bite. If you stop first, it leaves him wanting more, which he can only get from you.
I always do this with Salty and now he begs for scratchies, and never bites or nips in that situation.
Always try to avoid the bite. A parrot that doesnt know that a bite will stop you in your tracks from doing whatever it is your doing is one that is not likely to develope a biting habbit.
Hope this helps with your little guy.
