The red deer with all those sharp points can gore a lot of animals but the bison is so heavily built and armored it just gave it a little bump when it turned it's head and the bisons horns connect with the deer stunning it like a flash ko
This is in Russian I believe, but as far as I know Russia does not have any bison unless they were imported. This herd appears to be a managed group of animals, as that bison looks to be old and not that healthy. Also many of the elk doe have ear tags and that bull is very small for having a rack like that, so I am assuming these are a smaller Tule Elk or some other Russian small variety of elk.
Олень-то не дикий,а парковый. Заметно,что рога большие,а тело не развитое,мускулатуры вообще нет. Сравните с диким приморским изюбрем или маралом алтайским.
