2 Santa’s helpers
Reindeer were first associated with Santa Claus in a poem published by New York printer William Gilley in 1821: Old Santeclaus with much delight / His reindeer drives this frosty night. / O’er chimneytops, and tracks of snow, / To bring his yearly gifts to you. Two years later, Clement Clarke Moore’s better known poem, “T’was the Night Before Christmas”, featuring eight flying reindeer.

5 The end of an era
A millennium ago, there were wild reindeer in Scotland: the Vikings are thought to have hunted them. Reindeer became extinct in the UK about 800 years ago because of hunting – but also due to climate change. That’s a couple of hundred years after the last brown bear perished – but long before the last wolf, which is thought to have been killed in 1860.

11 Not to be sniffed at
The inside of a reindeer nose is an efficient heat exchanger, warming the cold air on its way in against the hot air being breathed out. They have a similar system with the blood in their legs.
