If there was a bison background character in one of my stories crafted for North American readers, I would likely merely mention there was a bison. I might call him majestic or large or hairy. But I wouldn’t go into much detail.
If I was describing THIS bison, I would likely devote some space to describing his horns.
Why?
Because they aren’t typical for a bison. They aren’t ‘normal.’
And because they aren’t normal or expected, they stand out and they warrant mentioning.
Mention the unexpected in your stories, especially if that unexpected detail is important to the plot or character development.
