March 17, 2018: Cackling or Canada?

In the foreground is a Cackling Goose on the left, with a Canada Goose on the right.  Note how much smaller the Cackling Goose is, plus the bill is quite short and the head is more rounder.  The Cackling Goose was once part of the Canada Goose complex, but became a full species many years ago. (Wolf. Oesterreich, 3/8/18)
