A visit to Fishers Green was undertaken to ring Black-headed Gulls on the Friday evening. Due to some issues with raft fences we were only able to visit two of the rafts and ring a sample of gulls. Common Tern nests were checked and counted and this was a useful exercise.

The Southern Colour Ringing Group rings Black-headed Gull pulli (young in the nest) nesting on rafts at Fishers Green in the Lee Valley Regional Park.

In addition to a conventional BTO metal ring, we also fit colour rings (yellow with a black code starting with '2') which allows the birds to be relocated without needing to be recaptured. There are many more bird-watchers looking for colour-ringed birds, so this greatly improves our chances of understanding the movements of the birds from the Lee Valley breeding site.

If you see a bird with one of our colour rings, please use the submission form or send details (ring-code, date, location, species) to This email address is being protected from spambots. You need JavaScript enabled to view it..
