I was in the store shopping for bird seed and came across a block of suet that claimed to be especially for woodpeckers. I was skeptical. How could a certain combination of suet, seeds, and nuts attract an individual species of birds? I bought it, took it home, and placed it with the bird feeders and was surprised (why was I suprised when the lable tipped me off?) to see that it had attracted three varieties of woodpeckers within a couple of days, along with all the other birds.
