Behavioural Evolution

The sugar glider behaviour towards human presence have changed after it have grown larger in size over a span of 1 month. Initially, the specimen will showed 3 obvious characteristics when anyone tries to approach it. Firstly, it would create noise which is known as “crabbing”. Secondly, it will shiver at one corner until left alone and lastly, it will excrete faeces when being grabbed or taken out from its cage. However, nowadays, when any stranger approaches the cage and opens the cage door, the sugar glider will hop out of the cage onto the hands of the person. When it does so, we will give it treats like fruits and sugar glider food and it will quickly grab it and jump back into its cage. The question now, is the sugar glider approaching us because it knows we provide food or is it just bonded with us. There was also an incident where we left some grapes in a plastic on the top of its cage and it chew throw the plastic and nibble on the grapes until it could drop into the hole of the cage. From this, we can see that the sugar glider have evolved smarter in the attempt of obtaining food.  On the 20^th May 2014, at around 2.47 am, I could hear a new behaviour which was shown by the sugar glider, it made not the usual sound but instead a hissing sound which we have never heard before.
