depends on the bird and how socialized he is. how he was raised, etc.
mine isnt very bitey. he pinches, but doesnt mean to hurt. well, not me anyway.
i have 2 tiels as well. dealing with their egg laying/breeding situation right now.
the amazon we have has taken a bite out me and drew blood, but it was my fault not his.
the amazon is smaller than my B&G, but very pretty. theres a pic of him.
