Bats in the Night Sky

We sit on our back porch, sipping a 1999 Ironstone Pressing. The nights are starting to draw in, with darkness creeping in at 7 something rather than 8 something as we move towards the equinox. The cicadas and toads are relatively quiet. But every now and again we see the silhouette resembling a raven flap across the night sky. Its a very large fruit bat. We've seen them take off in their thousands from the Botanic Gardens, and given that our neighbours have ripe mangoes hanging from their trees, its not surprising they come to visit. Yet it is still very shocking and alien.
