I have a 5 year old Blue and gold. I have had him / her for a year and he is friendly with everyone. Lately the bird has started nesting by taring up boxes in the corner of my room. The bird has started bonding more with me and now is starting to be less friendly with other members in the family as well as strangers. Prior to this change he would let anyone hold pet and love on him. I do like the fact that we have a good bond but want him to be nice to all people. Any advice?
