Peanut feeders attract woodpeckers, nuthatches, chickadees, titmice, jays, and more. They come in multiple styles and can be filled with peanut pick-outs or peanuts in the shell. Some peanut feeders are designed without perches, as to attract only the “clinging” birds and thwart sparrows. Larger birds such as blue jays and woodpeckers will eat peanuts in the shell, and love the peanut wreath feeder. Smaller birds like chickadees and titmice prefer peanut pick-outs and will eat those out of a mesh feeder without perches.
