When trying to take photos of the local Rock Doves, I noticed one individual had a ring on it's right leg. So I zoomed in and tried to capture as much of the ring info as I could. This resulted in me noticing the terrible state of the birds feet. Most of the toes were missing or gnarled, but the bird still walked as normal. I believe this can be caused by a mite infestation, and is obviously not caused by the metal ring. An investigation into the origins of this bird is underway, as it's number looks readable in the many photos taken (ES 58139).
I also downloaded some Rock Pipit photos I took yesterday, which included another very Grey looking bird. This bird had an extensive grey colour to most of it's upperparts, and flanks, but lacked the stonking White 'super' of the previous bird.

The colours in the photo below have not been altered.
