For most of my life, I thought seeing several hundred or even a thousand Canada Geese was a good flock. And sure enough, scrutiny of any "good-sized" flock (read: a few hundred) in my neck of the woods has a pretty good shot at turning up "something good", usually Cackling or Snow Geese or maybe if you're really lucky a Greater White-fronted or Ross's.

My view of Ontario goose migration, like so many other southern Ontario-centric birders, was extremely flawed. Southeastern Ontario is on a huge goose flyway along the Atlantic coast. In recent years, as the Greater Snow Goose migration has increased in southeastern Ontario, awareness of this seems to be increasing, but still most Ontario birders really don't appreciate how different goose migration is in the southeast.

Anyways, this is all to say that I am happy with an article I recently wrote for Ontario Birds. Here are a couple of figures to get you thinking:

You might notice a similarity with this:

Looking forward to hearing your feedback on this one!
