Is it one of Santa's reindeer?

This is the scene from my office window one night last week. Did it get to cold in the North Pole for Santa's reindeer?
Actually it is a regular deer we see them from time to time as they come out of the woods behind out building. This is one of the Fog rolling in, we have had a lot of fog here in the last week.
If you double click on the pictures you can see the deer better.
