With birds patience and time do a lot, they may not be the same everyday. I know that Bob is very feisty in the mornings and I do not attempt to get him out or hang with him. By early afternoon he is much better and works well with me. By evening he will cuddle on my shoulder.
In the morning Bob is too wound up to hang with, he also attacks his toys and screeches when I go into the cage with greens. He does not seem to like my hand in his cage in the morning.
Bob has bitten me very hard and would not let go before. I hung in there and tried to transfer his attention to something he could bite. He is better about biting now but I learned what he accepts and doesn't accept and the time of day to attempt things with him.
Also, some birds are cage protective and feel violated when we intrude. Bob is cage protective first thing in the morning, but I watched him for a long time in the a.m. and found he has a ritual of food and bells, and his ladder and so on. So, now I respect his space until at least lunch time.
You need to be careful not to constantly annoy him by trying to get him on your finger, I am afraid you and Bud may develop a pattern of bad behavior. I am pretty new to this bird stuff too, but I have had great success with Bob but I "listened" to him and respect his space and he trusts me more everyday.
Hang in there and don't be so hard on Bud and hard on yourself, someday you will look back and laugh about all you have learned.
i didnt know what to do and i didnt wanna fling him off so i let him for a min then after he bit me like 5 times he flew off.... he didnt want to come out after and he went to all his toys and were attacking them... IDK what's going on... he calmed down after a few mins but now he bites me almost everytime i put my hand by him....
