I have been filming a camp of Grey-headed flying foxes, Australia’s largest bat with a 1m wingspan and weighing up to 1kg, in Joalah NP. Their noise and the stench of their urine are pervasive. Their impact on the rainforest vegetation is noticeable. Even when they are roosting in the tops of palm trees, they are a fair distance from the camera. I filmed numerous adults cloaking young under their wings. Today a drop of bat urine hit my eye. They say urine is sterile. I had long wanted to film flying foxes, thinking it would most likely be at night because I thought they only visited the Mountain for food. It was only recently that I heard about the camp in Joalah.
