WHAT IS Project FEEDERWATCH?
Project FeederWatch turns your love of feeding birds into scientific discoveries. FeederWatch is a winter-long (November-April) survey of birds that visit feeders at backyards, nature centers, community areas, and other locales in North America. Participants periodically count the birds they see at their feeders and send their counts to Project FeederWatch. Your bird counts help you keep track of what is happening in your own backyard and help scientists track long-term trends in bird distribution and abundance. With FeederWatch, your observations become part of something bigger.
