Store-brand chunky peanut butter and store brand oats (the birds don't care about brand names, but don't use instant oats). Used to put raisins and honey in there at the beginning but learned they don't eat the raisins, don't taste the honey and I used to eat too much of it before putting it out for 'the kids'. Mix it by hand but the Kitchenaid works best. Takes a while to get the right 'consistency'. Drill holes in a dried out branch/log and fill with suet mixture. We get red bellies, yellow bellies, downys, hairys, chickadees, warblers, titmice, and wrens and the occasional raccoon, flying squirrel and CONSTANT visits by squirrels. and YES, i realize that "skunkbait's" post was four years ago, but somebody might get some good out of this post. I know we do. We fill the feeders when we get home from work and now during winter, the pine warblers are WAITING for us and land right next to us anticipating their yummy afternoon meal.
