Finally, researchers have been able to know about the secretive love life the koala, Australia's favorite marsupial. During the mating season, both male and female koalas show different behaviors. At one place, males hardly interact with other males in this season and females love to interact with others.

Study's lead researcher Dr. William Ellis from the University of Queensland said that koalas' call works two ways. It not only attracts females, but also warns other males.

Ellis said that koalas are quite loved by many people and enjoy such an iconic status, but then also not much is known about their mating habits. It is because of their private lifestyle. The researchers have unveiled that female koalas are 'reflex ovulators'.

It means that female koalas can only ovulate and become fertile after they receive stimulus like the male roaring. Koalas also have a breeding season running from September to December. Ellis said, "That means if you want to monitor a number of individuals in a population, you either need a pretty big field team where you're constantly watching them or you need to make use of some pretty cool technology".

He added that they used the second method. An experiment was conducted in which 21 koalas on St Bees Island were fitted with proximity logging-GPS enabled tracking collars. Through this device, the researchers were able to know with whom they have interacted and travelled.

After months of observation, the researchers came to know that especially in the breeding season female koalas become more social and spend more time together. Contrary to it, males do not interact much with each other during this time of the year.
