    Rangifer – Reindeer/Caribou

    Males drop their antlers before Christmas, but females keep their antlers until spring  

    Reindeer have s thick, brown coats during the summer and grey in winter. Their chest and underside are pale-colored, with a white rump and tail. Male antlers are larger and more complex than female antlers. They also have specialized hooves with footpads that turn spongy to give extra traction in summer and tighten and shrink from exposing the edge of the hoof to cut into the snow and ice so that they don’t slip.

    They travel distances that are greater than those traveled by any other terrestrial mammal, traveling up to 5,000 km (3,000 miles) a year and covering 1,000,000 km2 (400,000 square miles). In spring, migration leads them back to the calving grounds.
