On Greylag Geese, coloured legrings as well as neckbands have been used. During the last decades birds were mainly ringed with neckbands. The majority has been banded with codes placed as presented below. There is one upright ´large´ letter and under 90˚ two letters or numbers or one letter with one number are placed which in general have to be read from head to body (but there are some exceptions). The codes have to be entered with first the ´larger´ letter and then the other two, without space in between (so for instance A23). Codes like NX and XN or 09 and 60 have not been used at the same time (only when it is clear that the first one died).
The colours which are in use in the projects on this website are: blue, yellow, darkgreen, white and black. For other colours check www.cr-birding.org. Almost all birds which are equipped with a neckband also wear a metal ring on one of the legs. In some project (for instance in Sweden and Holland) also coloured legrings with in principle the same codes as on the neckband are in use. On these rings the codes are placed in line (see below) and have to be entered on the website with the abbreviation of the colour before the code. So a darkgreen legring with the code A23 should be entered as GA23.
