Where Do Bison Live ?
Before the number of bisons began dwindling, this great beast was found in most of the US, Canada, and also in some regions of Mexico. Today, the bisons live in sanctuaries and national parks across the US. The habitat of the bison in the US is plains, river valleys as well as prairies.
The bisons live in Yellowstone National Park, the National Bison Range located in Montana, the Wichita Mountains National Wildlife Refuge located in southwestern part of Oklahoma, the Fort Niobrara National Wildlife Refuge in northern part of Nebraska, the Sully's Hill National Wildlife Refuge located in North Dakota, the Walnut Creek National Wildlife Refuge in Iowa, and the Wood Buffalo National Park located in Northwest Territory of Canada.

When it is warm during the day, the bison usually rests while chewing cud. However, it can also spend the hot hours sitting in the dirt. The bison is extremely active during the early hours of the morning, and then during late afternoon. (See Reference 1)
Generally, bisons live in herds. Females and young males form herds that can comprise of twenty heads. The males can also form herds comprising of 20 or less heads, and at times the males can end up living alone. The older males and females tend to live separately. They only come together during the mating season. Each group will have a dominant female or male bison. (See Reference 1)
A female bison is ready to produce offsprings when she is around 2 to 3 years. However, a male bison is only sexually mature after reaching an age of 6 years. The mating season generally begins in the month of July and continues through September. Generally, a male ends up joining a group of female bisons, and the mating can last for a few minutes or run into many days. (See Reference 1)
After a female bison is impregnated, the gestation period lasts for around 9 months. When she is ready to give birth, the female will move an isolated place. A newborn bison calf is reddish brown in color. The calf and the mother do not join the rest of the herd for another few days. The calf is not born helpless. It has the ability to stand a few minutes after it is born. By the time the calf is 2 months old, it will begin forming the characteristic hump on the back as well as the horns, and by the age of 7 months, it is weaned off. (See Reference 1)
