Project FeederWatch, a citizen science program operated by the Cornell Lab of Ornithology and Bird Studies Canada, is "a winter-long survey of birds that visit feeders at backyards, nature centers, community areas, and other locales in North America" whose data "helps scientists track broad-scale movements of winter bird populations and long-term trends in bird distribution and abundance." While participation in this program requires a small fee, visitors to the Project FeederWatch website will find a wealth of free resources. For example, on the Feeding Birds page found under the learn menu, readers can read about different types of bird feeders and food types, ways to make backyard feeders a safe place for birds, and tips for bird-friendly landscaping. Under the explore menu, visitors can (for example) view maps created using FeederWatch data, see regional population trend graphs of their favorite bird species, and download year-end reports dating back to 2005. The community section of FeederWatch offers photos taken by program participants, tips on bird feeding from participants, and the Project FeederWatch blog. For readers who love their backyard birds, the Project FeederWatch website is well worth exploring.
