beakrubbing

I'm new to having a bird and I had some trouble with Mort (Nanday conure) being aggressive at first, especially towards hands. He's warmed up to me and especially my dad and he has started rubbing his beak against our fingers. He will come up to our bent knuckle and rub the side of his beak...

So, I am a new bird mom, who just brought home an eclectus over the weekend. He was a consignment bird, approximately 3-6 years in age. I have noticed that he seems to rub his beak on EVERYTHING. The bars of his cage, his sand perch, my pillows, etc. Most of what I can find online says that...
