Reindeer Caribou in Europe are named reindeer, while Alaska and Canada title only the domestic caribou “reindeer”.
To simplify matters though, throughout the world reindeer caribou are all considered to be the same species. I’d mentioned the Canadian caribous (x4) above in my last post. The four remaining ones are the Finnish forest reindeer (R.t. fennicus), Svalbard (R.t platyrhynchus), Greenland (R.t. groenlandicus) and lastly, European (R.t. tarandus).
Caribou is a member of the deer family “Cervidae”. Their large hoofs are concave in order to support them in soft tundra and snow. Interestingly enough caribou are the only deer species that have both sexes grow antlers. You may spot the occasional female with either none or simply just one. Antlers grow exceptionally quickly. For a male, in March you’ll see the little soft lumps on the head and by August they’ll be over a meter in length. By February, you won’t see any

caribou sporting their antlers – they lose them.
Bulls are the males and cows are the females. In Canada the Woodland Caribou is mostly clove-brown. Otherwise, the neck, mane shoulder stripe, belly, rump and the patch above each hoof are white. Bulls can be twice the size of that as a female. Average full grown males are 350-400lbs (159-182kg) whilst full grown females are on average 175-225lbs (80-120).
