Colour-marking of (Tundra) Bean Geese started in the 1970s in the former Eastern-Germany. However, neckbands observed today are likely to originate from the two current programme's that mainly use the systematic of ringing in Greater White-fronted Goose. Ringing has been carried out both in the breeding areas in Russia, and at the wintering sites in Germany, The Netherlands and Hungary. More recently, many Bean Geese (incl. Taiga Bean Geese) have been marked with blue neckbands in Scandinavia. Most neckbands are yellow and have a 3 digit code of which the latter 2 are placed in a 90° angle. Fewer neckbands have a code that is placed in one row. Especially these (older) neckbands are faded and may look white. When entering observations, first enter the code (e.g. A01) and then select the colour of the neckband in the dropdown menu. Note that with codes that have one 'large' digit and two smaller digits in 90° angle, always the 'large' digit should be entered first, followed by the 2 smaller digits that are placed in 90° angle. Do not use space when entering the code.
