hi i purchased the blacktailed from Holland from a dealer , the common gulls came from a private collector in Belgium, the greys were from a uk zoo , the black headed are from rescue centres , there are a few zoos around Europe who keep gulls iv not found any other private keepers of them as yet , it is a shame as they are fantastic birds to keep i get many hours enjoyment watching them they are great caricatures , the little black headed are looking very promising to breed it looks like i have 2 male and the one female and one male guards her constantly and the female is starting to look heavy , considering all 3 have lost best part of one wing in the last 6 months its amazing tough little birds they sure get my vote , do think about giving some rescue birds a home if you can in France its well worth it,
