A total of 79 pulli were ringed with metal BTO rings. Of these two have been recovered so far. The oldest British
Black-headed Gull recovery was a bird which was over 28 years old - so it’s quite possible we’ll get more records
from this batch over the coming years. The ringing was funded by
Moor Green Lakes Group.

The Moor Green Lakes colony was deserted this year following complete failures in the previous two years. A  small
number of birds turned up late in the season and attempted to breed. When we visited the colony on 3 July to ring
the Common Tern chicks there were 7 Black-headed Gull chicks and about 6 nests with eggs - some of which had
obviously been abandoned but a few were still being incubated. Three of the chicks were colour ringed and 2 were
just ringed with metal rings, the remaining 2 chicks were too small to ring. On 12 July there was a lot of disturbance
on the island and on 13 July a check from the shore showed there was very little activity and it appears that the
colony has been predated again - the likely culprit is Mink. Some of the Terns certainly fledged - at least half of the birds we ringed should have been capable of flight by 12 July and two ringed Common Terns juveniles at Lea Farm GP on 13 July and the ring numbers read with a telescope. The Gull chicks we saw on 3 July are unlikely to have fledged by 12 July.

Once again there was fairly late breeding attempt by a small number of birds but these were all predated before any chicks hatched and the colony was deserted for the season.
