Ring info

We did note on Sunday down at Southend that we couldn't find any Common Gulls with bling on their legs, unlike some of the Med and the Black headed Gulls, which I've sent off to find out the details on. I must admit I havn't rung one myself yet but don't see many Common Gulls with rings on. Some of the large gulls do, I've often thought that I don't see Common Gulls with rings on, maybe its due to them not feeding on the tips where ringing goes on. Who knows?
