They are eating my figs (thank goodness figs produce a lot of fruit) and the neighbours pears more. I saw about four or five in the neighbours tree at once. I hear the flap, flap, flap though the night and their squeaks. Plus them landing near or on my house at times. The plums, so far, don't appear badly effected, but I haven't checked my tree this morning yet.
I hear the possums growling at times. This could be at a rival, but I also suspect it's at their rivals, the bats. The dog next door goes mad at them.
Re the figs; I am not eating many of them at present, as figs are not my favourite fruit, but I will eat figs when the other fruit is finished, and figs give me fruit for a month or two after the other fruit is gone. Figs produce continuously through the fruiting season, unlike the other fruit which have their fruit and then no more. Figs tarts are nice, as cooking improves figs. If the bats leave me enough.
I do find the sky more interesting with bats whizzing across it (they can fly fast). It's them whizzing towards my fruit trees I find disturbing.
I think you would have enjoyed a scene I saw once in central Sydney. I was staying in a hotel on the eight floor and I looked out the window at dusk and the sky between the tall buildings was filled with hundreds (thousands?) of bats heading out for the night. Gothic!

The bats are not as thick above my house as this image, as they spread out, but still plenty.https://www.google.com.au/search?...
