We students at Valley View Elementary School in Columbia Heights, MN
predict that the first Robin will be spotted on April 8. We think the
males arrive just before the 36 degree isotherm and the females arrive at
the 36 degree isotherm.
We are wondering what the males eat when there is a food shortage.
