A wren analogue to the chicken story

Some time back I wrote about a bird's nest in my wife's helmet. We had left it on a hook in the shed all summer, and some feathered family took advantage of the cozy location. This weekend I had to work (see tomorrow's post) and no rain was forecast, so I left my helmet on the bike, covering the GPS holder. One day! Yesterday afternoon I noticed a wren flying away from my bike as I approached the area with a load of firewood. So I went over and  looked for droppings, figuring that even though the bike is no garage queen, there was no sense letting that acidic stuff make a permanent stain. No droppings, but a stick peering out from under my helmet. (One day!) I lifted the helmet to find a couple more twigs, and a ring of dust on the tank. One day!! Sorry—no photo; I immediately cleaned out the helmet, dusted off the tank, and went for a quick ride. One day, and the birds make a next in my helmet! I guess I just need to ride more...
