Rest periods generally last for 2-4 hours, and few are longer than 6 hours. Social Organization Giant pandas are solitary. Males and females occupy overlapping home ranges that vary in size from 2.5-4.0 sq. Females tend to concentrate their activity in a core area, which may contain important den sites and more nutritious bamboo. Males roam more widely, visiting the core areas of females and subadults.
Scent is the primary mode of communication for giant pandas.
Both males and females have a large gland, which they rub against surfaces to leave scent marks. Wild pandas have been found to repeatedly mark trees located along well-traveled routes. Studies have revealed that each panda has its own unique scent, and that pandas can distinguish between the scents of individuals. Olfactory cues are useful for long-distance communication. Male giant pandas scent mark throughout the year.
