I love Bluejays too!
When I was a little kid one day over my grandparents house a Bluejay came up to me out on their front porch. I gave it a few sunflower seeds and went back in to the house. The little bird flew up on to the window and called and called though the screen. I went back out and it came up to me once again and I gave it some more sunflower seeds. It then followed me where ever I went out front. Went on for a good hour or more. My grandparents snapped a few pictures. I have them in a photo album that I'll have to find. I'll post them in a bit.
