(Newser) – Climate change is blamed for a drop of nearly 60% in reindeer numbers in recent decades and scientists warn that Arctic ecosystems are likely to suffer as a result. LiveScience lists other surprising—and less depressing—facts about St. Nick's beasts of burden.

  • They're actually caribou. Caribou and reindeer are the same species. The term "reindeer" generally refers to domesticated caribou in Scandinavia and Siberia that are herded and used to pull sleds.

  • Though they're slow walkers, they can run at speeds of up to 48 mph.
  • They're champion travelers. Caribou trek up to 3,000 miles a year, more than any other land mammal.
  • They're built for cold. Hollow hairs that trap air keep the herds warm while grazing on the tundra.
  • Rudolph, Blitzen, and the rest of the gang are female. Male reindeer lose their antlers by December, meaning the team pulling Santa's sleigh is all-female, if the sightings are to be believed.
