Here's a comparison:
* Bison: An adult male bison can weigh between 1,000-2,000 pounds and stand 5-6 feet tall at the shoulder.
* Wild Boar: An adult male wild boar can weigh between 150-600 pounds and stand about 3 feet tall at the shoulder.
Therefore, a bison is roughly 3-4 times heavier and 1-2 feet taller than a wild boar.
