Bison calves tend to be born from late March through May and are orange-red in color, earning them the nickname "red dogs." After a few months, their hair starts to change to dark brown and their characteristic shoulder hump and horns begin to grow
Badlands is home to one of the largest federal bison herds in North America. In 1963, two truckloads carrying 25 bison each traveled from Theodore Roosevelt National Park to the Badlands.
There was once a time when bison roamed freely in huge numbers across the Great Plains. An estimated 30 million bison in the 1500s dwindled dramatically to less than 1,000 on the continent by the late 1800s. Conservation efforts in Badlands National Park began when 50 bison were reintroduced to the park during the 1960s, followed by an additional 20 bison in the 1980s. Today, the population has reached approximately 1,200 bison.
