    Default How do deer keep warm in brutal cold winter conditions

    I went for a walk the other day in the woods. -25 C and a moderate wind. Two layers of cloths and a down Columbia coat,long jons and tinsulate hunting pants. After 5 minutes I could feel the cold seeping in.

    It amazes me how deer,coyotes etc. can keep warm 24 hrs /day with no relief. A deers hollow winter fur is not that long and under belly,head nose etc. are somewhat exposed, They scrounge for every bit of edible food as there fat energy source is used up. Am I missing something here? What are other reasons how animals keep warm . Is it something in their matabolism ? Any comments?

    Um, maybe I'm having a moment, but aren't deer warm-blooded and fish cold-blooded? They're 2 entirely different things. I don't know the answer to the deer question though. Here's a bit of info I found:

    "One good thing: The metabolism of whitetails slows down in the winter, so the animals don't have to eat as much to keep their bodies going.
    The buck's thick winter coat keeps him warm. The dark-gray color helps absorb the sun's heat. In extreme cold, a deer tightens its skin muscles and the coat hairs stand on end. This traps air near the skin's surface, insulating a deer and keeping it warm. This process is called piloerection."

    I don't really know the answer to your question, but it is not cold that kills deer, it is longs spells of deep snow.

    deer never have to worry about cold unless its 50 below for a long period of time.

    SNOW is what the deer are worried about. Suppost to get down to -30 tonight . Deer will be moving more but it wont be that big of burdon on them. As long as they can find food under the snow

    Hound... I find they don't seem to mind the cold in the freezer, but I find they like it in the warm, beside the mashed potatoes.

    ela1; Yes fish are cold blooded however, Freezing water is still about 0 C
    Gofunkel ; Good reply. A deers winter coat and motabolism etc, keep it warm whereas humans need layers. Check out a bedding spot on the snow. Very little evidence of melting

    Deer have evolved to tolerate a wide range of climates. The winter coat on a deer is a big factor. Deer will seek areas with higher temps and bed down southern exposures in daylight and move when it is really cold. The snow depth is one of the biggest issues for deer mortality over the winter. The cold temps do factor in as they have to metabolize more fat reserves to produce heat. The length of the winter is another factor. They are pretty amazing critters.

    It is all conditioning, just like construction workers they work out in the cold they can take the cold a lot better then ones that don’t have the exposure to it, like mentioned before they are insulated very well so the heat loss is minimum, and they curl up with their back to the wind and head tucked in. they go in to a survival mode and lower there metabolism. That is why you have large body’s in the north so they can maintain core temperatures. John

    PS if a dog is kept outside it can take the cold if you kip it inside it will shiver in minutes in the cold.
    Man the top predator, man the ever powerful, he could mold his environment, man that changed the earth in his image. man that's so full of him self. Nature sneezes and puts him back in the stone age. The Oldhunter.
