Washing the windows a few weekends ago definitely needed to be done, but now several birds have flown into them (thankfully not too hard - yet). Most of the solutions I've read about (http://lifehacker.com/5911467/how-to-stop-birds-from-flying-into-your-windows), from using tape to decals, won't make my own view more attractive. However, hanging wind chimes just might be the answer.
Unbelievably, I don't have any wind chimes. So that will be rectified today. My desire for clean windows needn't be the cause of harm to the avian population. And of course, there are many inspirations on how to make them to be found on the internet.
