Before America was colonized, there were 60 million American bison. Next thing you know, they almost became extinct in the 19th century due to commercial hunting, slaughter, and the introduction of bovine diseases from increasingly distributed domestic cattle. Later, bison were reintroduced to the US, and now there are 20,000 wild bison and close to half a million bison raised as livestock.
Their mood can be judged through their tails. When the tail hags down and switches naturally, indicating that they are calm if the tail is standing straight up, beware!

How did they disappear?
This mountain of buffalo skulls might give you some idea of how they could go from a few tens of million to few hundreds in 50 years.
One notable example is the intentional killing of buffalo by the U.S. Army to subjugate the Plains Indians. General Philip Sheridan, a military leader during the Indian Wars, reportedly stated, “Let them kill, skin, and sell until the buffalo is exterminated, as it is the only way to bring lasting peace and allow civilization to advance.”
