Its section of
Anatidae Information in Japan 「全国ガン・カモ類飛来情報」 (only in
Japanese language) has an interactive system which allows users to input data
of flock size of Anatidae species observed in a site and codes of
colour-marked birds in the flock. The system can show information of former
observation data of each colour-marked individual.
Individuals are distinguished with attachment of coloured plastic neck-collars or tarsal bands which are engraved with unique codes in a combination of 2 or 3 alphabets and digits.
