"I started filming a video for an English language podcast I make in order to show the listeners what a cockatoo screech sounds like as I could hear some cockatoos screeching like crazy as I walked to the shops in North Melbourne. When I finally got close enough to see them I noticed they were screeching more than usual and then that they were fighting with a possum in the tree. I watched for several minutes as they tried to bite, claw and drag the possum from the tree. I filmed the fight. I went and did my shopping and then on my return past the tree it had happened in I saw the same two cockatoos looking under a car and walking around it.
