I just love my rascally Blue Jays. And you are right, they are not the Scrub Jays that you have. I have a hole in one of the posts on my deck. Sometimes I put a couple of peanuts in it just so I can see them turn their heads to eyeball down into the hole. LOL
It was pretty fun to watch the Clark's nutcrackers (a mountain jay) steal the dog's food out of the bowl, while intimidating the dog. The dog was an Australian Shepherd, and she would back up a bit, and watch, then dart forward and snap her jaws at the nutcracker. The nutcracker would retreat, then come back in when the dog wasn't looking.
I like the bluejays too. At the old place, I would put out peanuts for the squirrels, but the bluejays went nuts over them.
