wing-tags show an individual black four-character code, with
the upper row consisting of two capital letters and the lower
row of a two-digit number. This
project involving tracking individuals of known origin will
help determine whether the identification criteria for this
species have to be modified and will help us find out more
about individual strategies in both breeding and wintering
over extended periods. If you come across one of these gulls
please record all relevant details including date, site name,
geographical coordinates, code on wing-tag, number of other
gulls present, etc.
send the information and a photograph if possible to my e-mail:
You will receive all relevant data on your bird in return.
