When I first lived in Sydney I was shocked to find a fruit bat hanging off the tree right outside my front door staring at me as I left for work. They are very big (not like that bat though)
Got used to them would hear them in the night munching away at the fruit then see them as leaving for work just as they were falling asleep I was told they are drunk from the fruit
But one of those flying close to you was scary (only thankfully happened once)
