Happy #LunarNewYear!
Celebrate the #YearoftheRam (or Sheep or Goat) with these 3 fine fellows.
Camouflaged against the snow, Dall sheep thrive where few mammals can—above the tree line on windy peaks in Alaska and northwest Canada. Given their forbidding home, these three rams can afford to relax for a moment. While predators like wolves and bears do threaten, few enemies can pursue these nimble sheep up the very steepest cliffs.
The horns of a male Dall sheep can grow to 10% of its body weight.
