Project FeederWatch is a winter-long survey of birds that visit feeders anywhere in the United States and Canada. FeederWatchers periodically count the highest numbers of each species they see at their feeders from November through early April. FeederWatch helps scientists track broad scale movements of winter bird populations and long-term trends in the distribution and abundance of birds.
