Rudolph the reindeer could really have a red nose

 
Rudolph the reindeer could really have a red nose, say scientists.
Researchers in Sweden use thermal imaging cameras to capture the heat coming from reindeer as they graze to find that the animal’s nose glows.

They found that while most of the animals’ bodies are well insulated by their fur, their noses glow bright orange in the images due to the large amounts of heat they release. That’s because reindeer have a high concentration of blood vessels in their nose and lips to help keep them warm and sensitive when rummaging through snow as they search for food.
