I also have my doubts.
I've been up close to Woodland Bison, North of Fort Providence.
Here is one, laying beside the pavement;
Then just after he got to his feet.
My Brother and my one BIL both raised bison for a few years.
The biggest bulls they had would look like a yearling next the Bulls I saw in the NWT.
If I kneeled beside that bull in my first photo my eyes would be just above the top of his head. But in the video the hunter is behind the Bison, can't tell how far, and the camera angle is low. He should be barely able to see over the head of a Woodland Bison in that shot.
Another thing, I've spent most of my life in the Peace River/High Level area.
I don't know of any place where it's that open among the trees.
Every place up here I have ever been is a jungle of shrubs and saplings under the trees.
I lived in High Level for six summers. Did a lot of trekking through the bush up there. I never heard anyone mention seeing an Elk in that area.
One of my friends from that time still comes down here to hunt Elk every fall.
And last thing that makes me suspect this video, some of those small trees look like Cottonwood. Black poplar don't start to get cracked bark until they are over a foot across at the stump.
But there is just not enough for me to say I think it was shot in the USA, but I sure suspect that's the case.
Being that all three guys are from New York state that would be far more likely then them hunting the High Level area.
And it's the only place I know of in the province where one can hunt wild Bison in the province.
