Earth, water, air, and flyer...

First, I apologise for the terrible pun on the classic four elements, but it amused me....
Possibly my favourite blip photos are those that you just come across when you're at a loss what to photograph. I saw this as I left the office, walking to my car, thinking I had nothing from the day. Right by the car, bingo, the light on this puddle, then bingo, a bird flew over....and the blip was 'in the can'. Phew.
