North American Bison or Buffalo.

Niagara Falls: The picture you’re seeing it’s the North American Bison or Buffalo at Marineland Park. The North American bison, or buffalo, is the largest land animal in North America. A bull can stand 2 m high and weigh more than a tone. Female bison are smaller than males.
A bison has curved black horns on the sides of its head, a high hump at the shoulders, a short tail with a tassel, and dense shaggy dark brown and black hair around the head and neck. Another distinctive feature of the buffalo is its beard.
The picture it shows some of the features how to identify a bison by subspecies. In general, the plains bison is lighter in colour than the wood bison. The wood bison is taller, longer legged, and less stockily built than the plains bison, but it is heavier.
Signs and sounds: During the mating season, from July to mid-September, "bull roarings" are heard for kilometres, day and night, as bulls challenge each other in the rutting ritual of the mating season. Historically, bison were known to make movements of up to hundreds of kilometres to take advantage of the changing availability of food plants in different seasons. These movements were most pronounced on the Great Plains, where large herds moved long distances along traditional routes. Some of these routes are still visible from the air in the form of deep paths worn over the years in the prairie soil by millions of passing hooves. In contrast, the wood bison in the Mackenzie Bison Sanctuary in the Northwest Territories make only local movements during the year, moving between open meadows and the surrounding forest, in patterns established through traditional use. Most bison live in mixed herds of cows, calves, yearlings, sub adults, and a few bulls. The other bulls form groups of their own.
