Yes, gulls really do need friends.....
In more natural situations (so not Aberystwyth roof tops!) gull populations are struggling, with black headed gull, common gull, herring gull and great black backed gull all red listed by BTO/RSPB within Wales.
Med gull (localised breeder), little gull (European conservation concern) and lesser black backed gull (localised breeder) are all on the amber list.
Surprisingly, the gull we all find it more acceptable to like (and worry about), the kittiwake, is green listed in Wales now, having been moved from the amber list at the last review due to an apparently stable population
