This evening I was running a bit late for my fitness class and was hurrying out of my office building. As I fast-walked to my car, I could hear an audible "beep" sound from the road. Everytime a vehicle whizzed by, "beep" the sound would go.
I thought the traffic police had installed some motion detector device to count the number of vehicles which went by. But why on earth would the traffic police want a count of the number of vehicles? Oh, or maybe, they were tracking speed - but what an odd place to keep such a device!
By this time, I was quite captivated by the "beep" sound and decided to watch for a bit. Then I realized, the beep wasn't actually happening every time a vehicle went by. It just happened randomly.
Which was when I noticed - right on top of the stone name board at the entrance to the office complex sat a tiny brown bird. And every few seconds, it opened its tiny beak and went "tweet", "tweet". The "beep" sound I thought I heard was the tweeting of a bird!
As a city-dweller, how disconnected am I from nature that the operation of a motion detector seems to be a much more natural explanation for a beeping sound than the tweeting of a bird!
