Hi! My name is Kim and I am the now proud and frustrated owner of a beautiful Sun Conure named Packer (Green Bay Packers!) He's a pretty good boy, only 6 mo old, so very juvenile. He started out biting and now just pinches, but it is getting less and less. The screaming is another issue!
He is just a little baby screaming for attention. Don't give direct response to his screams. Just like a baby he will learn to scream for attention. Try to include him more in your day. He came from a busy place with other birds and needs more enrichment now.
Thanks for the advice. He can be a real stinker and a real lover and he is very spoiled. I am an artist and I can't get much done unless I put him in his cage. I really don't get much done. My biggest enjoyment is to give him a bath and then watch him preen for about an hour. His coloring is so beautiful!
You could buy/make him a playgym and hang toys from it to keep him busy. You should also teach him how to forage. This will keep him busy and exercise his little brain. Here are some great videos/articles to help you get started:
