From the rear it looks like a Robin.
No interactions present.
Any ideas about where I could sent the photograph of the ring for ID?
As cetacean says unless you can read all the letters and numbers on the ring you cannot. If you do have lots of high resolution images that let you do so then http://blx1.bto.org/euring/lang/pages/rings.jsp?country=EN will let you report it.
The ring is a BTO type. You need all the letters and numbers on the ring to see where it was ringed which sadly you cannot get from this photo.
OK folks, thanks; I didn't get close enough to get a clear definition of the ring, so will let it go.
