Så er geden blevet barberet. Fuglen er med i et Hollandsk forsøg, som det fremgår af nedenstående:"In 2004 the University of Groningen, has started a new wader-research in Southwest Fryslân, a province in the north of The Netherlands. We focus on the migration of Ruffs and the breeding ecology of Black-tailed Godwits. The use of colour-rings is an essential instrument in both projects. In the attachments you find a brief description of our research and the colour-ring scheme we use. More extensive information can be found on our website: http://www.rug.nl/biologie/onderzoek/onderzoekgroepen/dieroecologie/onderzoek/researchStudies/migratimmune.
Once a year I will send detailed information to the observers about the bird(s) they reported."
