In recent years I have seen more swans.  In March they were hanging out in a field near my home.  Now... I am looking for them.  The swans on the left I believe are Trumpeter Swans. The younger ones are grey. 

Below are what I believe to be Tundra Swans.  When I saw these guys I was wondering why there was such a color difference. Curt, my husband, was the one who told me that we have two types of swans in Minnesota.  So I did a little research.
