Koala Poo on the Driveway

Last night we could hear a male koala calling out, (really grunting) to find a mate. It's a scary noise if you haven't heard it before, kinda like a cross between a pig and motorbike! He kept going for hours. What stamina!
We've got an amazing Spotted Gum in our backyard - it's about 40 metres high and he was sitting up there announcing his presence to the world.
Anyway when we went to go to work we found his poo all over the driveway - so I took a photo.
