Until you get a chance to join in an ivory-bill search, there is one very important way you can contribute to the overall effort - by collecting data on another magnificent bird, the pileated woodpecker. We need data, data, and more data. Data on dimensions of pileated roost and nest cavities. Data on pileated foraging sign - gouge widths, bark adhesion, and so on. Data on pileated wingbeat rates and any color pattern anomalies. We need recordings of pileated rapping. Not to mention that becoming intimately familiar with the pileated will make you that much better an ivory-bill searcher when you do have the opportunity to enter its realm.
