There's no need to provide gourmet food here. Peanuts are a treat for many wildlife species. Offer them and you'll soon be treated to exceptional performances as birds and squirrels investigate and partake of this new food. Squirrel, jays, magpies, and many woodpeckers will make off with all the unshelled peanuts you can offer. Picture a diminutive chipmunk trying to stuff a three-nut unshelled goober into his cheek pouch.
Jays hide the peanuts in strange places.
Next spring, you can go on a treasure hunt, the course charted by the birds. How a bird knows that it should land on plastic netting and, with nearly surgical precision, extract a peanut kernel from the shell, we'll never know. For birds with weaker bills, shelled peanuts are a better choice. Buyer beware, however. The bulk seller of bird seed that tries to convince you that the little bitter peanut hearts are the preferred peanut food is either trying to dupe you, or, more likely, just doesn't know what tastes good to most birds.
