This year we joined a subspecies known as snowbirds. Just before the onset of winter, this group packs up and heads south to warmer climes, and when spring is in the offing they migrate northwards again. They're somewhat indistinguishable from the native southern species until they open their mouths and are betrayed by their northern 'accent', or by their habit of ending most sentences with "eh". Snowbirds are a subspecies of the species 'Can-eh-juns' - as pronounced by the southern natives - or more properly as Canadians, and hail from Canada - spelled 'C eh N eh D eh'.
A close analogy to snowbirds is the Canada goose - the ones pictured below are obviously not snowbirds.
