Here is a special paper for 6thIGM participants and other gull people: "The Identification of Yellow-Legged Gulls". It is a present from Norman van Swelm, who was not able to participate. It is almost totally in pdf-format, so use these links to read it. Start by NEWCACHINNA. It is perhaps good to open two pages, one for text-pdf and the other for pictures, so it easy to move between them.
Please, have a nice look. Comment to me if you have any problems in reading. Note that sizes of some files are about 600-870 kb, so the loading can take a while. (email:Risto.Juvaste@kolumbus.fi)
