Four simple ingredients, pine cones, peanut butter, bird seed and twine.
This one's messy so have the paper towels ready.
First, tie the twine good and tight around the pine cone.
Next, slather peanut butter all over.
Finally, hand off the buttered pine cones to your helpers so they can roll them in birdseed.
Interestingly, our smaller birds didn't seem to know what to do with these but our neighborhood woodpeckers showed up right away (click on either image to see a female downy woodpecker)
And as expected, the squirrels took several of them right away -
