Koalas do have times when their mating season is at its peak. Their peak mating season also depends upon the region they are living in as well. For example, the Northern koalas from the Queensland region have the peak mating month in November while the Southern koalas have their mating season at its peak during the month of December.

The peak mating season within koalas occur during the summer season. The peak mating season for the Northern koalas occurs during the month of November while for the Southern koalas it occurs during the month of December.

These observations do indicate that the summer season is the peak mating season for the koalas because the months of November and December are considered as the beginning of the summer months for the Australia’s Northern and Southern regions respectively. On the other hand; some other sources reveal that the peak mating season within koalas occurs during the month of September.

During the mating season the male koalas are very vocalized. Their vocalization could be heard at the night time when they are usually very active. Male koalas vocalize loudly to attract the female koalas within their territories and the nearby areas. Furthermore; the male koalas also tend to mark trees with their scent marking which is released from their chest and they also mark the trees with their claw marks as well.

Male koalas tend to vocalize at night to attract the female koalas. Male koalas also scent mark the trees to let their presence known to the rival male koalas as well.

The purpose of this overall activity is to let the other males to stay away from their territory. Occasionally; the territorial conflicts also occur in between the male koalas which are usually brief but decisive.

On the other hand; the female koalas are quite receptive to the loud vocalization of the male koalas during the mating season. Usually the female koalas greet the male koalas with a low snarl or a weak bellowing. As the male koalas’ approach near the female koalas, their (female koalas) snarling gets louder and louder.

Female koalas are quite receptive to the loud vocalization of the male koalas. However; females do tend to struggle away from the male koalas at the time of mating.

Whenever the male koalas approach the female koalas, females are mostly reluctant and tend to struggle away from the male koalas. On the other hand; the female koalas with babies are often very aggressive towards the male koalas and a quarrel may erupt between the male and female koalas, if the male tries to breed. The joeys (having an ability to come out of pouch) with the females often cling to the back of their mother during the fight while the joeys less than 6 months old tend to remain inside the pouch.

The breeding season also allows koalas to become a bit social as well. Koalas are solitary animals and the breeding season is the only way when the adult male and female koalas get socialize with one another. According to researchers, koalas spend 93 percent of their time alone during the non-breeding season. Whereas; during the breeding season, koalas spend 86% of their time alone.

The koalas’ breeding season does allow the adult koalas to briefly socialize with other koalas. Koalas are 7 percent more socialized during the breeding seasons than during the non-breeding seasons.

The mating time of koalas is quite short and it lasts around a minute or two. Therefore; the mating season does allow the adult koalas to briefly communicate, interact and build a short-term relationship with other koalas. Other than that, koalas are strictly the solitary marsupials.

Lastly; during the mating season, koalas also face two key challenges. First the dog attacks and second one includes the road accidents. Experts have noted that during the breeding seasons, koalas are always on the move and they shift from one tree after another in search of their mate. Male koalas are especially very active during the breeding season.

During the mating season, koalas face key challenges of the dog attacks and the road accidents. Both of these challenges prove out to be very fatal and deadly for koalas.

This is where things get bad for them and they may end up facing the domestic dogs in both the urban and the rural areas. Similarly; koalas also move from one territory to another. They may have to cross roads and might suffer from the road accidents as well. According to the estimates, most of the koala road accidents and dog attacks occur during the peak months of the koala mating season.
