My macaw lunges at me all the time and usually doesn't bite that hard, or not at all. He's never left a mark. I don't flinch in the slightest when he does but I can't decide weather I should tell him no when he does or just totally ignore it as it doesn't bother me much. If I completly ignore it and give him no reaction whatsoever will he eventually give up and stop doing it or is it better to tell him no when he does it.
