We have the lesser snow geese. Interesting facts
HERE
You would have both lessers and greaters coming through Quebec. The greater snow goose migration route is rather narrow compared to the pretty much continent wide migration of the lessers.
Interesting facts for greater snow geese
HERE
Now if you want to know every species of bird in Saskatchewan, all 383 are listed
HERE (the Passenger Pigeon is shown and noted as extinct). Those that are noted as rare or accidental are certainly that - I've hunted for decades and not encountered them. I did not know wild turkey have been surreptitiously introduced (gotta learn more about that) I have never seen a greater prairie chicken. And to think I content myself with a few roosters in the midst of all this bounty (no, we don't shoot the song birds etc etc)
Cheers,
Jack
