A female Long-tailed Duck has been visiting various urban water bodies along the south side of the Thames for the past few days. Peckham, Greenwich, and now Rotherhithe, which is where I caught up with it this evening. It shows like a dream, at times coming too close for my long lens. I love birds like this, and I don't care where they come from as long as I get to see them! The light was pretty OK for the 6-7pm slot, so real complaints at all from me on that score which is pretty unusual!
