This really depends on numerous factors; of course, it is not the easiest thing to attract woodpeckers to your backyard. However, it is possible to do with the right accommodations and patience. It can vary from a few weeks to a few months to even a year or longer before spotting a woodpecker. Attracting woodpeckers to your yard can be a challenge, but one that is well worth it for bird lovers! If there is a woodpecker nearby, it won't be as hard to attract them as if there are no woodpeckers in your area.
