Not to put too fine a point on it.... But from very personal experience, I know those to be African Geese, you can tell by the hard high bump on their forehead. Some of the quickest and meanest of fowl.
My maternal grandmother raised them for many years, first as hatchlings at her home in the small village where they lived in MN. When they were of sufficient size they were moved to 'the farm' just outside the village, all of 15 acres. It was my assigned duty to water the beasties twice a day, more if it was hot.
It didn't matter, goose or gander, if they took a dislike to you, they would put their heads down low to the ground moving it from side to side like a Cobra, hiss, flap their wings, and chase you for as long as you were in sight. Mean buggers and quick to nip at a boy's bare legs, while he was encumbered with pails full of water. I truly have first hand knowledge of the term 'goosed'.
Maybe that is why I've never felt bad having a Thanksgiving or Christmas goose.
Seems I recall one of our far northern members saying 'revenge is a dish best served cold' or, at least, as left overs.
