The male koala has a scent gland on his chest. This is how he marks his territory, rubbing the gland on tree trunks to let others know when it one of his home trees. The scent gland stains his chest fur a brownish yellow colour.
Normally, yes male koalas are larger than female koalas.
The males have a brown patch of fur on their upper legs and groin area. It is the glands where the male gives off its scent for marking family territory. The females, not needing to mark their territory (hence the need for a mate), do not have these glands or fur coloration.
Only the male koala has a scent gland which he uses to rub against the trunk of a tree. He is scent marking to indicate his home trees, and this is to attract the female, rather than to mark territory. Koalas have a range of around one square kilometre, and they have numerous home trees within that territory. Male koalas use scent marking to have a possible mating with females who then pick up their scent from the tree trunks.
Yes. Male koalas will engage in territorial disputes during breeding season.
Male koalas fight for territory, females, and a sense of dominancy (higher ranking) within a group or family.
Male koalas become quite territorial during breeding season.
All koalas, both male and female, react similarly when they are in danger. They climb the nearest tree in order to escape the danger.
Koalas are not bears. Koalas can be male or female, otherwise they could not reproduce.
Not at all. Male koalas will readily breed with numerous different females each season.
Yes. Koalas are not monogamous, so once the male has mated, he moves on. The female raises her joey alone.
No only female.
The ears of male and female koalas do not differ in any way. The only way koala ears differ is that koalas from southern parts of Australia have ears which have shaggier fur and tend to be browner in colour.
