Lumholtz's tree-kangaroo are solitary animals, except for male-female mating and the long, intimate mother-joey relationship. Each kangaroo maintains a "home range" and will be hostile towards a member of the same gender that enters it (the one exception seems to be non-hostile encounters between adult males and their male offspring). Thus, the male will vigorously protect his home range and visit the females' ranges in his group. Mating takes place in episodes of about twenty minutes and is often quite aggressive.
