Scrub Jays are easy to train. Just set a few peanuts out at the same time every day and it doesn't take long for them to get the idea. I think I gave them 100 lbs in a year. The next year, I spent all my time picking peanuts off the roof, from under rocks, out of rain gutters and picking up shells the dogs had found. Jays don't like you taking their hidden stash!
