* Food Availability: Squirrels primarily eat nuts, seeds, and fruits. These food sources are most readily available during the day.
* Predator Avoidance: Squirrels have many predators, including hawks, owls, snakes, and even larger mammals. Being active during the day allows them to rely on their strong eyesight to spot danger.
* Energetic Needs: Squirrels are very active animals. Their high energy demands are better met by foraging during the day when they can maximize their food intake.
* Social Behavior: Squirrels are social animals and often live in groups. Being active during the day allows them to communicate and interact with other squirrels more effectively.
* Body Temperature: Squirrels are homeothermic, meaning they can regulate their own body temperature. This makes them better suited to the warmer temperatures of the day.
While squirrels are primarily diurnal (active during the day), some individuals may exhibit crepuscular behavior, meaning they are most active during dawn and dusk. This is likely a strategy for avoiding peak predator activity while still taking advantage of food availability.
