My sun conures ability to trust

Question
I have had my conure for about five weeks, and we adore him.  He loves for us to take him out of his cage. He sets on my shoulder while washing the dishes or anything. He kisses and cleans our hair or face but he will not let us touch or stroke his back.  He will sqwack and move away. Why is this, he seems nervous but at the same time he seems to love us.  By the way his name is Clyde and us is my husband and two sons.  

Answer
Hi, Treynolds.  Thanks for posting.

Most likely, your conure doesn't like you touching or stroking his back due to instinct.  In the wild when a predator wants to grab a bird, it lands on or grabs the bird from/by it's back.  Also, a bird's wings are it's only way of fleeing from danger.  A lot of parrots don't want this only means of escape hampered by human's hands preventing them from beng able to flap their wings and, thus, getting away.  Lots of tame parrots don't like their humans messing with their backs...this is normal parrot behavior.  You can gain your conure's trust, however, by touching/stroking it's back when it will allow you to do so in order to show s/he that you mean s/he no harm.  Don't force it, but use certain situations to your advantage.  In other words, when your conure is enjoying it's time on your shoulder, every now and again try touching/stroking it's back.  He'll eventually learn to trust you.  It's only been 5 weeks, so give it some time.
