- The tendons in a reindeer’s feet slide over the bones and produce a clicking noise when they walk. It’s believed this noise helps them locate each other in blizzard conditions and keep the herd together. Also useful when “rockin’ around the Christmas tree,” since reindeer have no fingers to snap.
- Reindeer can see ultraviolet light. They’re the only large mammal who can. It helps them locate predators and lichens, which absorb ultraviolet light and appear black against the snow. It also means they don’t need a special light to enjoy black light posters.
- Reindeer are the only type of deer in which both males and females grow antlers. They shed their antlers each year and grow new ones. The males usually shed theirs around November, but the females keep their antlers until their calves are born in the spring. That means Santa’s hardworking reindeer must all be female. No wonder they can get so much done in one night.
Merry Christmas, my deer!
