Only very experienced zoologists can figure out pregnant females.Most calves are born in late April, when it is already quite warm, a polar day begins, but the herd has not yet migrated. A muskox is born in 8-8.5 months old calves. However, this defensive formation makes musk oxen very vulnerable to human hunters.

Males compete for the right to breed with the females by strutting, swinging their heads and ultimately charging into one another head-on. Their scientific name translates as “musky sheep-ox”.

Where do musk ox live?The natural population is found in Canada and Greenland. The American bison and European bison (wisent) have been hybridized with domestic cattle.With wisent, this was originally done in an attempt to reinvigorate the declining wisent population.First generation hybrid males are sterile, but females may be crossed back to either a wisent or domestic bull to produce fertile males. By the middle of the 19th century, the only remaining populations of musk oxen were found in the tundra of the Canadian Arctic. The calves weigh 8-10 kg; they have a thick layer of fat that protects them from frost. The rut in musk bulls starts in July-September. Their name derives from their musky odour and from their superficial resemblance to the ox, though they are not closely related to cattle. In the warm season, the bull eats grassy plants, which at this time are actively developing. The calf can stand and follow its mother within a few hours after birth, which is a necessary requirement to outrun potential predators. Para obter mais informações, veja os.
