Buffalo / Bison
American Buffalo (Bison bison) It is believed that buffalo, or bison, crossed over a land bridge that once connected the Asian and North American continents. Through the centuries buffalo slowly moved southward, eventually reaching as far south as Mexico and as far east as the Atlantic Coast, extending south to Florida. But the largest herds were found on the plains and prairies from the Rocky Mountains east to the Mississippi River, and from Great Slave Lake in Canada to Texas. more info

Because the great herds were nearly gone before any organized attempts were made to survey populations, we may never know just how many
buffalo once roamed North America, although estimates range from 30 to 75 million. "The moving multitude...darkened the whole plains," wrote Lewis and Clark,
who encountered a herd at South Dakota's White River in 1806.
By 1800, the small buffalo herds east of the Mississippi River were gone. Buffalo may have been killed to protect livestock and farmlands in that region.
With westward expansion of the American frontier, systematic reduction of the plains herds began around 1830, when buffalo hunting became the chief industry
of the plains.
Conservation of the buffalo came slowly. In May 1894, Congress enacted a law making buffalo hunting in Yellowstone National Park illegal.
Eight years later, money was appropriated to purchase 21 buffalo from private herds to build up the Yellowstone herd. With adequate protection,
this herd has steadily increased until it numbers almost 4,000 animals today.
Although the buffalo's size and color, which ranges from light to dark brown, vary in different areas of the country, experts generally agree that all
American buffalo belong to the same species. The differences in appearance probably result from the variety of environments in which they live.
Like their close relatives, domestic cattle and sheep, buffalo are cloven-hoofed. Both males and females have a single set of hollow, curved horns.
The male buffalo, called bulls, are immense, often weighing a ton or more and standing 5 to 6 feet high at the shoulders. The huge head and great hump
covered with dark brown wooly hair contrast sharply with the relatively small hips. The females, or cows, are not as massive. Despite their great size and
bulkiness, buffalo have amazing mobility, speed, and agility, and are able to sprint at speeds of up to 30 mph.
In the spring, buffalo begin to shed their heavy winter coats, and soon their hair hangs in tatters. To hasten shedding and possibly to relieve their itching skin,
buffalo rub against large stones and trees. By late spring, the only remaining long hairs are on the head, forelegs, and hump. To escape the torment of
attacking insects, buffalo wallow in dust or sand.
