It is very common for the male Koalas to have different territorial encounters and fights with one another on variety of occasions. Usually the core reason in between the fighting and territorial encounter is the area to rule for any male koala. Koalas are usually very calm, and the territorial encounters and fighting in between the koalas is very rare. Moreover, from the nature’s perspective for the male Koalas it is not in their best interest to fight, because they will lose energy and calories and it will be hard for them to actually reload into their bodies.
The fighting starts whenever, a dominant or a bigger koala spots a smaller male Koala on the tree. If the bigger male Koala is on the move to relocate and wants an ideal tree that comprises of better nourishments, surely it will see if there is any competitor for it. Whenever, it will see a competitor it will be ready for the fight to take a particular territory. Usually there are rare occasions that they fight. Mostly the younger and smaller sized koalas run for their life, when they see a bigger and stronger Koala.
However, sometimes, it does happen that the bigger male Koala grabs the smaller male Koala and this is where the fight starts, but smaller male Koala will always fight. It will both climb to the tree top at maximum and then try to come down and leave the territory for the bigger male and so on. In some cases, the other competitor is of the equal size. This is where the competition arises and that’s where the ultimate territorial fights in between two male koalas start.
