How far are you willing to go to get some free bird feeders and bird seed? If you are an experienced backyard bird watcher, and willing to count the birds at your feeder for 45 minutes every other day, then Project Wildbird will send you a whole load of good bird feeding equipment to participate in their ground-breaking research on seed and feeder preferences in backyard birds. If you can't commit to that level of bird observing, there are other ways to participate--but you'll have to provide your own feeders and seed.
Project Wildbird has already greatly expanded our understanding of what seeds are preferred by different birds, and how those preferences vary across the country and over the course of the year. I got a sneak preview of some of the initial study results, and I'm anxiously waiting to hear more as the study progresses. If you haven't heard of this project, take a look at the website, and contact my friends over at Project Wildbird to sign up to help out with the study.
