Featured Facts

The American bison once roamed the Great Plains and prairies of North America in unbelievable numbers.  Estimates run between 40 and 60 million bison.  Today, approximately 350,000 bison inhabit the region.

Bison are frequently called buffaloes, but this term is meant for bovines inhabiting  Africa and Asia.  With a height of 5-6 feet, length of 7-11 feet, and weight up 2,000 pounds for bulls, they are the largest land mammal in North America.

Here are a few more interesting details about bison:

• Sheds its thick, shaggy mantle in the spring.
• Due to nearsightedness, vision is poor, but retains keen senses of smell and hearing.
• Average life span runs between 12 and 20 years.

Today, nearly 30,000 wild bison are located on national parks and wildlife reserves.  Yellowstone National Park is home to nearly 5,500 in two large, migrating herds.  Ranches contain over 300,000 animals, who are treated more like livestock.

Answer to Brain Teaser Question

100

Watch what you are dividing.  You’re not dividing by 2, you are dividing by 1/2.  Remember your basic skills.  Dividing by 1/2 is like multiplying by 2. 

So the answer is 40 x 2 + 20 = 80 + 20 = 100
