The reason why the coyote is there is the same of why the wisent is on eurasia: it's the most recognizable and iconic of all the animals in the pack, That's it, there isn't really an complex reason.
But is the wisent that? I mean i love that animal, but id be lying if i said the swan and boar are not infinetly more recognizable than the wisent, which even in its native range seems to not be a well known animal among the casual people, anecdotal evidence i know but thats waht i observed atleast*
*When i was at my local zoo with my family last year, which only keeps only native animals, my sister was confused about why there was a north american animal all out of sudden. And when i asked my best friend if you could guess what germanys heaviest animal was he didnt even know what a wisent was.
Is the coyote the most recognizable animal out of the ones teased? Maybe, id probably give that to the flamingo but sure.
Altough i think similar to the tasmanian devil, there are probably way more people familiar with the name rather than the actual animal
