Lovely writeup on our Canada Jay!
I put black oil sunflower seeds out for the birds but the whiskey jack won't come for them. The only time they came around lots was when I had some fat or suet out - they love that!
I miss the Gray Jays but we have lots of Blue Jays!
I use black oil too for all the other birds... the Jays prefer kibbles, bread and nuts or other scraps... normally I don't like feeding bread to the birds but the Jays and Ravens are scavengers anyway, so they eat things we wouldn't think of. We don't have Blue Jays here, would love to, but it's too cold!
