Peanut butter pudding:
Peanut butter is a good substitute for suet in the summer. Mix one part peanut butter with five parts corn meal and stuff the mixture into holes drilled in a hanging log or into the crevices of a large pine cone. This all-season mixture attracts woodpeckers, chickadees, titmice, and occasionally warblers.

Fruit for berry-eating birds:
Fruit specialists such as robins, waxwings, bluebirds, and mockingbirds rarely eat birdseed. To attract these birds, soak raisins and currants in water overnight, then place them on a table feeder, or purchase blends with a dried fruit mixture. To attract orioles and tanagers, skewer halved oranges onto a spike near other feeders, or provide nectar feeders.

Nectar for hummingbirds:
Make a sugar solution of one part white sugar to four parts water. Boil briefly to sterilize and dissolve sugar crystals; no need to add red food coloring. Feeders must be washed every few days with very hot water and kept scrupulously clean to prevent the growth of mold.
