Think
about when robins usually arrive in your area. Look at your region as
you watch the animation a couple of times. What are the average temperatures
during the month when robins usually arrive? (You can translate these
from centigrade
to fahrenheit.)
Look at
the regions where the Northern Observation Posts are located. In what
month(s) do the NOPs experience similar temperatures? Consider this
