Toad Tuesday

National Bison Day is an annual commemoration of the ecological, cultural, historical and economic contribution of the American bison (also commonly known as the American buffalo) to the United States. It has been held each year since 2012 on the first Saturday in November. Bison supporters, including Native Americans, bison producers, conservationists, sportsmen, and educators typically plan local events and social media engagements celebrating and promoting the bison. A campaign is underway to pass federal legislation officially recognizing National Bison Day. Although the legislation has so far failed to pass, the Senate has passed a resolution each year since 2013 recognizing the day.

Bison

From Wikipedia, the free encyclopedia
The American bison and the European bison (wisent) are the largest terrestrial animals in North America and Europe. Bison are good swimmers and can cross rivers over half a mile (800 meters) wide. They are nomadic grazers and travel in herds. The bulls leave the herds of females at two or three years of age, and join a male herd, which are generally smaller than female herds. Mature bulls rarely travel alone. Towards the end of the summer, for the reproductive season, the sexes necessarily commingle. American bison are known for living in the Great Plains. Both species were hunted close to extinction during the 19th and 20th centuries, but have since rebounded. The American plains bison is no longer listed as endangered, but the wood bison is on the endangered species list in Canada. 
Although superficially similar, physical and behavioural differences exist between the American and European bison. The American species has 15 ribs, while the European bison has 14. The American bison has four lumbar vertebrae, while the European has five.  ...  Adult American bison are less slim in build and have shorter legs. American bison tend to graze more, and browse less than their European relatives. Their anatomies reflect this behavioural difference; the American bison's head hangs lower than the European's. The body of the American bison is typically hairier, though its tail has less hair than that of the European bison. The horns of the European bison point through the plane of their faces, making them more adept at fighting through the interlocking of horns in the same manner as domestic cattle, unlike the American bison, which favours butting. American bison are more easily tamed than their European cousins, and breed with domestic cattle more readily.

Habitat
American bison live in river valleys, and on prairies and plains. Typical habitat is open or semi open grasslands, as well as sagebrush, semiarid lands, and scrublands. Some lightly wooded areas are also known historically to have supported bison. They also graze in hilly or mountainous areas where the slopes are not steep. Though not particularly known as high-altitude animals, bison in the Yellowstone Park bison herd are frequently found at elevations above 8,000 feet and the Henry Mountains bison herd is found on the plains around the Henry Mountains, Utah, as well as in mountain valleys of the Henry Mountains to an altitude of 10,000 feet.
European bison tend to live in lightly wooded to fully wooded areas and areas with increased shrubs and bushes, though they can also live on grasslands and plains.
