A yellow naped amazon parrot was in my backyard, I gave him an orange and he quickly came over to me. He must be someone else's, but whoever the owner is, he or she never put a notice or sign in the neighborhood. So it's been a month I have been taking care of it. Anyway, at first he was very gentle and played with my fingers or ear, but now he nibbles too much and harder and he gets too excited that I cant make him stop. I try saying a firm "no" or put him away for awhile. When I put him away he will cling so hard to my fingers or shirt and sometimes is so hard that his nails will pierce my skin and he wont get off. I dont know what to do! How do I train him to be calmer and stop nibbling so hard? He always wants to get out of his cage (I dont make him get out of his cage, he seems to want to).
