They are usually in a larger group right now or paired off. I read they are one big happy family with hierarchy. Though, many of the juveniles are pushed to move onto thier own family. Maybe your Jay hasn't made his family life yet. I've read this but do not know how reliable the source is. I'm going to look into it, as I just adore the peanut grubbing Blue Jays. :)
I hope to get a Hummer. I dug out another garden bed. I have a lot of garden beds now, with much just for the Hummers. They are crazy if they don't stop by. LOL!
Don't work too hard in the pasture. I wish I had pasture. I have to move someday to a more rural setting. I don't belong here. :)
Hummingbirds may be small birds with tiny brains, but once they discover what a lovely set up you have for them, you'll get more than you can imagine!
