Looking at birds rings ....

Nipped over to WCPS this afternoon after work for a bit of a diversion from birding on foot from home and trying to identify every living thing in my home square. My intention was to look for colour-ringed gulls and get some photos, but by the time I left work and got there the fog had descended and it was dank with no decent light for photography. Didn't see any colour ringed gull either, but managed to get some grainy shots of a couple of metal rings that are barely discernible and are incomplete. I've made the shots greyscale and reduced the noise in photoshop to produce something just about worth posting.
