  1. My blue jays eat everything in sight and leave nothing for the squirrels (peanuts and sunflower seeds are what I put out) . What can I put out that the blue jays DO NOT LIKE so the squirrels get to eat too?

  2. After 46 years of backyard feeding birds and accumulating squirrels, raccoons and possums (at night) mallard ducks year ’round (Indianapolis), I have had to force some kind of separation between all of them. Our squirrels kinda drive off the birds, so I have to put suet, which my wife makes in a Cuisinart, out on a shepherd’s crook pole which they can’t climb for the woodpeckers, downy wp’s., etc. BJ’s will eat kernel corn but compete with the squirrels, so I have a feeder in a separate garden with peanuts and kernel corn. Our squirrels are hilarious, but I want our birds to have equal opportunities. We’re old enough to be Disney People and try to maintain equal opps for everybody. I feed oil sunflower in one feeder and a blend of oil sunflower, and other seeds in the other. Plus ear corn in the middle. Lesson learned – NEVER feed peanuts in the shell unless you want to constantly rake your lawn. BJ’s love them, but the lawn will be a mess. Our yard if approx. 50′ X 50′, with trees in a woods behind, I think our environment lends itself to favoring the squirrels, but I try to keep everybody happy. Every now and then, I try to have meetings with everybody to get suggestions, but they just run or fly away. Kinda like a few of the companies I worked for for over the years. Nobody agrees on anything.

    • Awwww how awesome. I SEE 2 Blue Jays everyday. They are so awesome to watch.
      I have also seen a Baby Cran

  3. Thanks. We found a baby blue jays in our yard. He’s doing great and my boys are trying to get emotionally ready to release him this weekend. He is very social and I hope he’s prepared for life away from his adopted family.
