Gray squirrels predominantly feed on tree nuts, but will also eat flowers, seeds, fungi, insects and even the occasional bird eggs. In addition to serving as an important prey species, the nut storing tendencies of the gray squirrel help to disperse tree seeds within their habitat.hese small, tree-dwelling rodents fit easily into a number of habitats due to their remarkable adaptability. Gray squirrels are easily recognized by their gray coat (varying from yellowish gray to pure silver, though different color morphs exist), ruffed tail and cream-colored underbelly.
Adaptations enable living organisms to cope with environmental stresses and pressures. One common form of physical adaptation is acclimatization. Acclimatization allows the organism to survive in a new environment. Adaptation can be structural or behavioral. Structural adaptations are special body parts of an organism that help it to survive in its natural habitat (e.g., skin color, shape, body covering). Behavioral adaptations are special ways a particular organism behaves to survive in its natural habitat.
