Canada geese, often referred to as Canadian Geese, are the second largest waterfowl in North America. (The largest is the swan.) They’re also the most widely distributed, with a range that encompasses arctic, sub-arctic, and temperate regions in Alaska, Canada, all of the lower 48 states, and Mexico. They’re also found in Greenland, northern Europe, and parts of Asia. Introduced populations have established themselves in New Zealand.
Only the females are actually called geese. The males are known as ganders. And the young are goslings. A large group is called a flock. A flock on the ground is known as a gaggle. And geese flying in the characteristic V-formation are referred to as a wedge, team, or skein.
