Squirrels, being omnivores, have a diverse diet that includes nuts, seeds, fruits, fungi, and occasionally insects. Their primary source of nutrition comes from nuts such as acorns, walnuts, and pecans. Squirrels are known for their habit of storing food, creating hidden caches to sustain them during periods of scarcity.

Their diet is rich in proteins, fats, and carbohydrates, providing the energy needed for their active and agile lifestyles. Additionally, squirrels may consume fruits, berries, and vegetables, contributing to a well-rounded nutritional intake.

Water is obtained through their diet and is supplemented by their ability to extract moisture from the food they consume. Overall, the varied and adaptive eating habits of squirrels contribute to their survival in diverse environments.
