Musk oxen live in the frozen Arctic and roam the tundra in search of the roots, mosses, and lichens that sustain them. In winter, they use their hooves to dig through snow to graze on these plants. During the summer, they supplement their diet with Arctic flowers and grasses, often feeding near water.

Arctic Adaptations

These animals have inhabited the Arctic for many thousands of years, and their long shaggy hair is well adapted to the frigid climate. The outer hairs, called guard hairs, cover a second, shorter undercoat that provides additional insulation in winter. This undercoat falls out when temperatures climb at winter's end.

Female musk oxen carry their calves during an eight-month pregnancy, but after birth, there is little time to waste. The infants are able to keep up with their mothers and the rest of the herd within a few hours.

Herd Behavior

Musk oxen are herd animals, and groups of two or three dozen animals are sometimes led by a single female. Herds use cooperation to deal with predation by wolves or dogs. When threatened, they “circle the wagons” and array themselves with their young in the middle and their sharp horns facing outward toward their foes. A cornered musk ox can be a fearsome enemy, charging with its massive bulk and attempting to use its horns to deadly effect.

Such defences are not terribly effective against human hunters, who killed great numbers of musk oxen for their hides and meat. Today, legislation protects herds in Canada, Alaska, Norway, and Siberia, where the animals live on preserves and National Parks.

The Musk Ox is my favorite animal. If there is a trip to be taken to photograph them, I have researched it, or planned a workshop to go photograph them. I lead workshops to photograph the Musk-Ox. I lead a workshop every year called Wildlife Bootcamp, where we can photograph Musk-Ox in the Yukon. I am also leading a workshop in 2023 and 2024 to photograph the wild roaming Musk-Ox in Norway. You can see all those workshops on my Wildlife Workshop page. See these workshops here
