Did You Know? Dall Sheep can see danger from far away because they usually live in open mountain areas with clear views in every direction.

Habitat and Distribution

  • Live in high, rocky mountains and steep cliffs.
  • Prefer cold and windy alpine environments.
  • Found mainly in Alaska and parts of Canada.
  • Choose areas where predators cannot easily reach them.
The Dall Sheep habitat includes treeless slopes above forests, where snow covers the land for many months each year.

Diet and Feeding Habits

  • Dall Sheep diet is completely herbivorous.
  • Eat grasses, sedges, shrubs, mosses, and lichens.
  • In summer, they feed on fresh green plants.
  • In winter, they dig through snow to find dry plants.
As plant-eaters, Dall Sheep play an important role in controlling plant growth in mountain ecosystems.

Behaviour and Lifestyle

  • Live in herds for safety.
  • Females and young stay together in separate groups.
  • Males often form small bachelor groups.
  • Very alert and quickly climb cliffs to escape predators.
  • Predators include wolves, bears, and golden eagles (for lambs).

Life Cycle and Reproduction

  1. Mating Season: Occurs in late autumn.
  2. Horn Battles: Males clash horns to compete for females.
  3. Birth: After about 6 months, a female gives birth to one lamb in spring.
  4. Young Stage: Lambs can stand and walk within hours.
  5. Adult Stage: Fully grown in a few years and join adult herds.
