A Swan

My office windows are rectangular, long in the vertical and high up. I see three quarters sky to a quarter rooftops. Today's bitter snow-filled clouds are passing right to left as is usual. But unusally today I have just watched a swan fly past. I don't think I have ever seen a swan flying before, especially high in the sky like that. I worried about where it was coming from, although it looked like it was going to Finsbury Park. For some reason I was concerned that it might not have the energy to get there.
