Caribou (adult male)

Caribou
Rangifer tarandus groenlandicus
The caribou is a North American deer of the same species as the reindeer of Eurasia. Both males and females have antlers. Caribou usually live in small herds of cows and calves and a few bulls. The staple diet of caribou is lichens, but they also eat grasses, shrubs, tree shoots, and mushrooms. Plans for oil- and gas-pipeline construction in Alaska and Canada were altered, through environmentalist efforts, so as not to interfere with caribou migration.
