I used to be a disgruntled Bison. Now I’m just gruntled. Well, someone has to do the grunt work. Oh, hey there. Ever wonder what sound a bison makes? No? Well, keep scrolling then. If you’re still here, the answer may not come to you as fast as "moo" for a cow or "baa" for a sheep (we assume they came fast to you), but that’s because bison make a variety of sounds. These sounds include anything from the low rumblings of male bellows heard during mating season to the high-pitched bleats of a calf looking for its mom. Other common sounds consist of snorts, coughs, roars, grunts, and an exasperated sigh heard just before you go flying through the air after not respecting the disgruntled bison’s space.
