I personally think the Blue Jay is one of the most stunning birds on the property. Their bright white, and deep black, feathers set off the multiple shades of blue spreading from head to tail. I've heard that Blue Jays are mean -- aggressive toward other birds. This hasn't been my experience. Of course, Jays don't have to BE mean. As soon as the smaller birds see a large bird, or shadow, approaching -- they typically don't wait around to see if they should be scared. Good thinking!
Blue Jays LOVE peanuts. They take them small. They take them large. And, when time permits, they take them ALL. You'll see a snippet of all three types of peanut-feasts. I found the "all" feast to be the most amusing. The Jay is like a PEZ candy dispenser in reverse -- he loads 'em up and sucks 'em down!
