Crab apples, air dried and frozen on the tree, provide this fox squirrel with winter energy to stay alive in sub-zero temperatures. Although squirrels prefer other foods, crab apples provide about 3.2 kJ / gram of energy (Nutrient Facts, n.d.) and squirrels probably find them easier to access than acorns buried under up to a foot of snow and frozen soil.
