Reindeer



Chistmas 2009

Each day from now until Christmas day one article will be devoted to a subject connected with Christmas. Today we take a look at reindeer.

The reindeer (Rangifer tarandus), also known as the caribou when wild in North America, is an Arctic and subarctic-dwelling deer, widespread and numerous across the Arctic and Subarctic.

The reindeer is a widespread and numerous species in the northern Holarctic. Originally, the reindeer was found in Scandinavia, Eastern Europe, Russia, Mongolia, and northern China north of the 50th latitude. In North America, it was found in Canada, Alaska (USA), and the northern conterminous USA from Washington to Maine. In the 19th century, it was apparently still present in southern Idaho. It also occurred naturally on Sakhalin, Greenland, and probably even in historical times in Ireland. During the late Pleistocene era, reindeer were found as far south as Nevada and Tennessee in North America and Spain in Europe. Today, wild reindeer have disappeared from many areas within this large historical range, especially from the southern parts, where it vanished almost everywhere. Large populations of wild reindeer are still found in Norway Siberia, Greenland, Alaska, and Canada, with a singular herd of approximately 50 Reindeer living around the Cairngorms region in Scotland.
Domesticated reindeer are mostly found in northern Fennoscandia, Russia, and Iceland (where they were introduced by humans in the 18th century). The last remaining wild reindeer in Europe are found in portions of southern Norway. The southern boundary of the species' natural range is approximately at 62 degrees north latitude.
A few reindeer from Norway were introduced to the South Atlantic island of South Georgia in the beginning of the 20th century. Today, there are two distinct herds still thriving there, permanently separated by glaciers. Their total numbers are no more than a few thousand. The flag and the coat of arms of the territory contain an image of a reindeer. Around 4000 reindeer have been introduced into the French sub-Antarctic archipelago of Kerguelen Islands.
Caribou and reindeer numbers have fluctuated historically, but many herds are in decline across their range. This global decline is linked to climate change for northern, migratory caribou and reindeer herds and industrial disturbance of caribou habitat for sedentary, non-migratory herds.

In the Santa Claus myth, Santa Claus's sleigh is pulled by flying reindeer. These were first named in the 1823 poem "A visit from St Nicholas", where they are called Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Dunder, and Blixem. Dunder was later changed to Donder and—in other works—Donner (in German, "thunder"), and Blixem was later changed to Bliksem, then Blitzen (German for "lightning"). Some consider Rudolph as part of the group as well, though he was not mentioned in the poem. Rudolph was added by Robert L. May in 1939 as "Rudolf the Red-Nosed Reindeer".
