Correct Answer:

It is nocturnal

Explanation:

The key characteristic that distinguishes the Flying Squirrel from other native squirrels in Pennsylvania is its nocturnal behavior. While most squirrels, such as the Eastern Gray Squirrel and the Fox Squirrel, are diurnal and active during the day, Flying Squirrels are adapted to be active at night. This nocturnal lifestyle allows them to take advantage of reduced competition for food and predators during nighttime hours. Their big eyes are a feature adapted for low-light conditions, enhancing their ability to navigate and forage in the dark. Their unique adaptations for night activity, combined with their gliding capabilities, make the Flying Squirrel stand out among Pennsylvania’s native squirrel species.
