While removing the buffalo east of the Mississippi took settlers over 100 years, the remaining 10 to 15 million buffalo on the Great Plains were killed in a punctuated slaughter in a little more than 10 years.
"We were expecting to find that the bigger, stronger guys — the high-quality males — would have the loudest bellows, because they can handle the costs of it," said Megan Wyman, a graduate student in geography at University of California, Davis and the lead author of the study.
"But instead, we found the opposite." Another surprising finding is that sometimes the males are more interested in other males. A calf is protected not only by its mother, but also by the whole herd.
Usually, she will give birth to only one young at a time, though twins have been recorded. Here is the classification of bison, according to the Integrated Taxonomic Information System (ITIS): Kingdom: Animalia Subkingdom: Bilateria Infrakingdom: Deuterostomia Phylum: Chordata Subphylum: Vertebrata Infraphylum: Gnathostomata Superclass: Tetrapoda Class: Mammalia Subclass: Theria Infraclass: Eutheria Order: Artiodactyla Family: Bovidae Subfamily: Bovinae Genus: Bison Species: Millions of bison roamed North America in prehistoric times, according to the U. But by the late 1800s, only a few hundred bison were left in the United States.
As European settlers pushed west, they reduced the animal's habitat and hunted them to near extinction.
These large animals mate around August of every year.

The males tend to fight and bellow for the choice females, but research shows that females may prefer the quieter males.
Today, while not endangered, bison are not doing very well.
The American bison is listed as near threatened by the International Union for Conservation of Nature (IUCN) Red List.
The American bison can be found in the United States, Canada and Mexico, mostly in conservation areas, preserves or farms.
