In spring 2004 a German team of ornithologists coordinated by Andreas Buchheim ringed and wing-tagged a total of 170 adult (including a few subadults) Mongolian Gulls Larus mongolicus in north-eastern Mongolia. The major aim of this activity was to get information about migration routes and wintering grounds of this little-known taxon. Each bird was ringed with a metal band (issued by the German ’Helgoland Ringing Centre’) on its right tibia. To ensure specific and individual recognition the birds were additionally fitted with white wing tags showing an individual black four-character-code: the upper row consisting of two capital letters and the lower row of a two-digit number.
