Sign of the Season

Current scorching temperatures notwithstanding, fall is clearly coming to my neck of the woods. I saw my first true snowbird the other day.
When I lived in Ontario, I always watched for the first robin of spring. Now that I live in a place where we see the robins in the winter, I watch for fall's first snowbird.
Snowbirds can be confusing. In spite of their ordinarily migratory nature you'll often see see the Damyanky Arveeus year-round. They are an American snowbird that migrate for two or three years but eventually find that they enjoy the wide variety of citrus fruits and golf courses and establish permanent nests. Often these nests are in preserves and they quite naturally will flock with other members of their species. It is virtually impossible to spot them once they shed the tags assigned them by the home state.
On the other hand, the Canadian variety (Canuckiseh Arveeus) is easy to pick out. Even on the coldest mornings (by Florida standards) they can be seen in their light weight summer plumage. Usually spotted travelling in pairs they prefer large vehicles (either minivans or Buick's) and are easy to distinguish from other Canadians with similar plumage by their slow rate of travel. Other than their high tolerance for cooler temperatures and differing origins C. Arveeus is virtually impossible to distinguish from the more common D. Arveeus.
