The Sugar Glider (Petaurus breviceps) is a small, omnivorous, arboreal, and nocturnal gliding possum belonging to the marsupial infraclass. The common name refers to its preference for sugary foods like sap and nectar and its ability to glide through the air, much like a flying squirrel.
Sugar gliders are highly social animals. They live in family groups or colonies consisting of up to seven adults, plus the current season’s young. Up to four age classes may exist within each group, although some sugar gliders are solitary, not belonging to a group. They engage in social grooming, which in addition to improving hygiene and health, helps bond the colony and establish group identity.
Within social communities, there are two codominant males who suppress subordinate males, but show no aggression towards each other. These co-dominant pairs are more related to each other than to subordinates within the group; and share food, nests, mates, and responsibility for scent marking of community members and territories
