How are our feathered friends? The Cornell Lab of Ornithology organizes a network of volunteers to monitor the numbers of birds that visit backyard feeders. For a small annual fee, volunteers get bird identification guides and data sheets, though they must provide their own feeders.
The data from Project FeederWatch is used in many scientific journals, tracking the populations and ranges of the most commonly seen backyard birds. The study runs each year from November to April, so get feeding and start watching!
To practice, can you identify the birds in the photos below?
