Great for the classroom or the individual, this download includes a quick guide to common Northeastern birds found at feeders in the winter and a double tally sheet to track birds over the season. Results can be tallied and graphed (bar and pie), showing most common species and rarer ones. Correlations can be drawn from weather and temperature data. This is a fun way to introduce math concepts through a love of animals! Easy and fun art activity inspired by Charley Harper!
