Nature walk to work

OK, so I'm on my way to work, walking through Waterloo Park.  I stopped to take a picture of this tree that had fallen over the weekend (I keep my camera in an easily-accessible pouch just for such occasions).

After I took the picture, I noticed this going on.  Warning: explicit!


And then a few metres down the trail I witnessed this high-speed chase!

All in a day's walk, I suppose.
