These past two summers I have been spending time recording colour ringed gulls in the breeding colonies, rather than trying to ring new adults. This is because there is greater value to my studies by identifying the nesting sites of as many of my known birds as possible. A recent trip to colonies on Sark enabled me to identify the nesting sites of 57 gulls (40 LBBGs and 17 Herring Gulls). These records included one LBBG known to have been raised on Burhou, Alderney, which has clearly recruited into a colony on a different Channel Island.
