Abstract

A ll living things show various adaptations to cope with the challenges in the environmental conditions. With the changes in the temperature at winter, the challenges arise such as to find food to meet the required amount of energy. Some of the behavioral characteristics of the animals are intended to prevent or to reduce the heat loss from the body (1). The selection of suitable feeding grounds with the desired thermal property is one of the behaviors that reduces heat loss. Nest construction and also behaviors to come together are the behaviors that are aimed at maintaining the body temperature. Most living things are somnolent and minimize their energy requirements by lowering metabolism in order to overcome these kinds of difficulties (1). Mammals has been evolved as having the proficiency to keep the body temperature higher than that of the environment (ambient) and at that level constant using the heat produced by internal
