March brings spring* and spring brings wholesale change to high latitude environments. Animals that fled cold regions as winter approached begin to return to take advantage of the short growing season.
Animal migration patterns can be used to study how climate changes. By examining migration dates and, in the case of birds like these, the hatching of young chicks, a record of the large scale seasonal patterns can be assembled. This kind of analysis is called "phenology".

Many Canadians learn a song, sometimes sung to keep up a steady rhythm while paddling a canoe, that features these lyrics.
My paddle's keen and bright Flashing with silver Follow the wild goose flight Dip, dip and swing Dip, dip and swing her back Flashing with silver Swift as the wild goose flies Dip, dip and swing
