Robin Map Questions
Robins Seen 03/24/09	Average Temperatures March 15-21, 2009
An age-old theory about robin migration says that robins arrive in an area when the average temperature is 36 degree F. Study this week's robin migration map. Draw a line just above the pink dots (sighting reports for First Robin Seen dated last week). Now look where the temperatures were 30-40 degrees. Do you agree with the theory? Why or why not?
Circle the Northern Observation Posts (yellow stars) on the map where you predict robins will be seen in the next 2 weeks. Use the temperature map to help you predict.
