Trip Report - Gull Ringing 29 June 2003

a team went out to the Outer Bund at the end of June to ring an annual quota of 500 Gulls for English Nature. Sarah Dawkins reports ...

Having visited the Outer Bund on 15 June to undertake the colony count and assess the best date for ringing, it had been decided that today was the day to ring the majority of the gull chicks. Hence a team of 6 met bright and early at the Nene End before driving around to the back of the seawall to begin the walk out across the mudflats to the Outer Bund on the falling tide.

Approaching the colony, it was clear that this was going to be perfect timing for the ringing phase of the gull monitoring contract as there were good numbers of very large gull chicks running around the grassy slopes.

Operating as a team we rounded up small groups of chicks from the slopes and creched these with a team to do the ringing whilst a couple of people checked through the rocks for more chicks. We operated like this for four hours (with a brief respite for lunch) and, by the time we were due to depart the island, had managed to use 443 of the 448 rings we had with us. Obviously, we couldn't leave it like that and three people went off to see what they could find, returning with 5 birds and the perfect species mix to finish off the ring strings! Our initial assessment had been spot on and most of the chicks were the perfect size for ringing; we would not have wanted to delay another week - some of those caught flew off when released!

Most nests had hatched by now. Chick mortality was not particularly high, although a few very large and well-feathered chicks had succumbed since our last visit. There were a few more dead adult gulls than on the previous trip including just one recovery of a herring gull.

Team returned to the seawall at about 4pm very hot and tired, and smellier than I care to remember - and this time there wasn't even the option of a shower at base before the journey back to Norwich!
