    Students think that the weather has been warmer this winter and some of the
    robins have migrated earlier or maybe stayed around for the winter especially
    in some of the areas further north of us like in MN and Canada.

    Students also noticed that the bird books that they were using for the range
    maps were pretty old. They were Golden Eye books published in l949 and l956.
    The migratory patterns could have changed since then. They also thought that
    the changes in the ozone layer may have also have affected the migratory
    patterns and the range map.
