Description

Deer start to prepare for winter months before the temperatures begin to drop. They do this by storing fat around internal organs and under their skin which insulates and provides energy reserves for the lean months ahead.

Their coat plays a major role in keeping them warm. Coarse, hollow, dark guard hairs cover soft, woolly underfur. Guard hairs can absorb solar energy but it’s the underfur that provides the most insulative value. Half the length of guard hairs, underfur is 5 times as dense. For comparison, sheep underfur is only 4 times as dense. The underfur traps layers of air, with warmer layers closer to the skin. The insulative value of underfur is increased when the hair stands on end (goose bumps for people) trapping more air.

Sebaceous glands in the skin produce a water-repellent oil that coats hair filaments as well

Deer decrease movement activity thereby lowering their metabolic rate and voluntarily reduce food intake.

eer also seek shelter in conifer stands. These areas have reduced wind speeds and snow pack and provide overhead thermal cover which means higher night time temperatures.
