2018 05 23 Seventy Acres 08

The first visit to the rafts at Seventy Acres Lake was made today primarily to count nests. There were a few young Black-headed Gulls to ring and it was pleaseing to count some Common Terns that had laid. Final total count for the morning was 142 pairs of Black-headed Gulls and 9 pairs of Common Terns. We will probably make a visit to ring more gulls next weekend. One bonus was on counting some gulls that had nested on wire cages for fish refuges we discovered a Pochard sitting on a nest which trapped itself in the cage. A quick grab and it wa secured for Adam to gain a ringing tick!

Methods

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..
