"B. lesueur" is very vocal, communicating through grunts, hisses, and squeals. It shelters in burrows, the only macropodiform to do so. Burrows vary from simple tunnels to complex networks with multiple entrances and deep, interconnecting tunnels. These elaborate burrows, or warrens, have been seen having from four to 94 entrances. Warrens are communal, housing an average of 20-40 bettongs. Bettongs appear to switch warrens from time to time, though each has one or two preferred warrens. During the day in the warrens, they form groups of one male and one or many females; males never share warrens with other males. Some of the female-female groups seem to be mother-daughter associations. However, individuals seem to forage alone, showing none of the day-range group associations.
