This is so sad. I love Canadian Geese (I just wish they had the sense to be from somewhere else). We have a pond in our back yard and sometimes when I'm outback I am lucky enough to see a flight of them glide in and land on the water. On occasion it actually brings tears to my eyes because they are so very beautiful and graceful in flight.
Hearing a shotgun blast and then seeing them fall, wings stilled forever before they splat on the water brings tears of joy to MY eyes.
They are crap machines and restrictions on hunting them has resulted in overpopulation and acres of filth on area beaches and parks.

It's two hours of birds flying all over the place.
Great photography, though.
