Alien Invasion?

This morning, at about 10 to 6 (!!!), as I was getting ready to let the hens out, I heard a strange sound coming from I knew not where. It was ethereal. I turned my head this way and that without being able to locate it. Then suddenly, out of the corner of my eye, I saw something overhead that seemed to be the source of the heavenly ringing. I rushed in to get my camera.



I have no idea where they came from, or where they were going to. I have even less idea why they were emitting such strange musical tones. But it was a magic moment. I think it was what the ancients had in mind when they imagined that the universe made music.

And here am I in the middle of London!
