Reindeer don't fly but they do sometimes have red noses!

Here are some interesting facts about these animals:

• Reindeer or in North America called 'caribou' are the only species in which the females also grow antlers in order to defend food in small patches of cleared snow.
• In colder climates the increase in blood flow in the nose will help keep the nose's surface warm, so that the air gets warm too before it gets to their lungs.
• Golden eagles are the leading predator of caribou calves in the late spring and fall.
• Caribou migrate over 3,000 miles in a year, more than any other land mammal.
• Some subspecies have knees that make a clicking noise when they walk so the animals can stay together.
