Why don't deer freeze to death in winter?
White-tailed deer adjust their metabolic rate, home range, and food supply in the winter. During the longer summer days, deer have a higher metabolic rate to take advantage of higher quality and more abundant food supplies. During the shorter days of winter, they lower their metabolic rate and reduce their body temperature. They survive on lower quality food such as white cedar and mountain maple twigs. They need to eat 6-8 pounds of this reduced nutrition food. Deer also reduce their home range in winter. They often stay in the shelter of a conifer grove, especially at night. Studies have shown that night temperatures in these groves are up to 60 degrees warmer than out in the open. A deer's heavier winter coat, with its hollow hairs, also provides needed insulation against the cold. Deer also match their reproductive cycle to the change in the seasons. They mate in fall. During the early part of their pregnancy, which occurs during the worst of the winter, the fetus develops very slowly and requires very little from the female. During the last trimester, the spring thaw provides more and higher quality browse for the mother such as aspen, willow, and birch. The fetus then grows rapidly and is born after the snow melts.

Thanks for the feedback!
Part of the answer is that their fur helps trap heat close to their body. Secondly, their skin is black which helps absorb rays from the Sun that do reach the north pole. And …lastly, a healthy dose of body fat provides insulation to keep their internal organs warm.
because the ice on top of the water has little atoms stick to each other and sir gets grapes in side between the atoms which makes ice flot on top of the water and that preven…ts the water from freezing and also the water below is moving in rivers and oceans
Birds actually use several tricks to keep their legs from freezing. First they can stand on one leg and pull the other up under their feathers when one leg starts getting too …cold. And if it gets really cold, they can squat to cover both legs with breast feathers. If you see a bird doing this, they may be getting uncomfortably cold legs.Also birds’ feet are mostly bone and tendons, so unlike mammals, they have a limited supply of nerves, blood vessels or muscles to freeze. Their feet are also covered with scales which isn’t a living tissue and less susceptible to freezing.Finally, birds don’t have sweat glands in their skin to produce any moisture to freeze. Heat and moisture are accumulated in sacs, transferred to the lungs and eliminated through the mouth. No moisture escaping through their feet is also the reason they don’t stick to metal perches in the winter.
I've heard a couple different things about why this could be. 1. It's a fight-or-flight reflex. The only "defense" (if you could call it that) that it knows is to s…tand perfectly still, almost like it's playing dead, except it's usually still standing. 2. It's a challenge. The deer is staring you down, and may attack if approached further. It's a form of "You'd better leave me alone, or I will attack."
I would think it is to protect each other from predators, as they are unable to run as fast in the deep snow.
The oceans are saline or salt water. This affects the temperature at which they freeze. Plain water freezes at about 0°C at sea level, but saline, at the concentrations norma…lly found in the ocean, freezes at close to -2°C. Pressure also affect freezing temperature. The deep ocean is at great pressure, so even though it can be at temperatures of -3°C it does not freeze. The temperature of the surface of the ocean varies from about -2°C to about 34°C depending on currents and latitude. Much of the surface of the Arctic ocean is frozen all year round, but the extent varies during summer and winter. An area of the sea around Antarctica also forms sea ice in winter each year, but much less area is permanently frozen than in the Arctic.
Deer manage through the winter by keeping warm beneath their hides and by digging through snow to uncover grasses. Note that "old" grass retains much of its nutrient value. It…'s just dry and brown. Deer also nibble on any trees or on bushes that have any leaves left on them. They even eat bark and twigs, which they don't do in the "greener" times of the year. Certainly anything like sagebrush that keeps its foliage all the time is food. Note that wildlife biologists encourage folks not to feed deer in winter. Winter feeding is done in rare cases where deer, elk, or the like gather in large herds within protected areas (where there is no hunting and limited predation), but this is the exception. Deer will browse on any plants they can get their teeth on in winter. Vegetation varies a lot throughout the range of these animals, so what is available in one locale isn't necessarily on the menu in another. But there is browse available for the animals or they wouldn't be there. Deer move around through a given year, and a lot of the shifts involve a change in altitude. By moving to lower elevations in the winter, they avoid the deeper snows that make their food too hard to get at.
Deer eats pine trees and bateria located in the woods
Fish go further down than the ice. The ice usually doesn't freeze all the way to the bottom. If the fish are trapped in shallow water or if the lake or stream freezes to t…he bottom, they will freeze.
You can give the deer corn. Or if you have apple cores you can put them out there for the deer
Deer do not go anywhere in the winter, during which season they stay in their home territory.
Yes, it has happened to quite a few people.
This is not a scientific answer, but, I have noticed that the summer coat color will match the colors in which the deer finds itself. The light brownish color matches the clay… dirt and is of the earthtones. This holds true for the winter coat. In the winter, the leaves are gone and the brownish coat that gave them the invisible status is gone too. Winter brings the gray dead look of the tree trunks, and dead leaves on the ground, without any foliage and the deer's coat will change as God's way of providing the animals with the protection of invisibility in the winter. That's my take on it.
Hypothermia refers to the body's inability to maintain internal temperature, which drops to the point where bodily functions can no longer continue normally. It is a dangerous… condition that can lead to death. The expression "freezing to death" is not accurate, because death comes well before the body reaches freezing temperatures. A more accurate term is "dying from exposure" (to low temperatures). The human body must maintain an inner temperature that will allow the chemical reactions that sustain life to occur. When it drops too low, the body's own temperature regulation system malfunctions, and even if the outside temperature is brought up to normal, the body's systems may not "restart" properly. Treatment includes bringing the victim's temperature up by keeping them warm externally, giving them warm liquids if they are able to take them orally, and getting them to medical care as quickly as possible. Children succumb more quickly than adults, because their small bodies lose heat faster. Hypothermia can occur at any time when the outside conditions are such that the body's heat is carried away faster than the body can generate it. For example, water carries heat away from the body rapidly, and hypothermia can occur in water as warm as 75 degrees F. if the body is immersed long enough. This is especially true if food is not available. Deaths from hypothermia often occur in temperatures well above freezing on land, as well, when people are caught away from shelter under conditions where they cannot stay warm -- such as hikers who get wet from a sudden rain in low temperatures (50° F. or less) and are unable to get dry or out of the wind. It is far easier to avoid hypothermia to begin with, by carefully planning for the possibility of deteriorating conditions in advance, than it is to treat it once it has occurred.

A dogs nose does not freeze in the winter because it contains a blood flow. It may not also freeze because there is warm air that goes in and out of it at all times.
Emperor Penguins do not freeze to death in the Antarctic as they are well adapted to their surrondings. A penguin doesn't freeze to death because: It has a thick layer of blub…ber or fat to keep it warmIt has black skin which is good at absorbing and keeping in heatA penguin's Feathers are tightly compact and when a penguin 'preens' itself by putting a special oil made from a gland in its tail on it, it becomes Waterproof.When penguins do get cold, they huddle together for warmth. To you or I it i cold in the Antarctic but to a Penguin, it is normal as it has adapted to the cold weather, just as we have adapted to our surrinding
