Each year approximately 1.5 million geese overwinter in the Netherlands. The mild weather and abundance of meadows and fields make the birds feel at home. With such a large migratory goose population, the country has some responsibility in their welfare. Through an extensive ringing program, questions about the origins and habits of the geese can be answered.
The geese are ringed either around a leg or the neck. The markings are clear enough to be read through binoculars at a distance, to avoid the need to re-catch the same individuals multiple times.
The Goosetrack program will allow the public to contribute to the welfare of the Dutch geese by taking part via SMS and the Internet. Ring data can be sent to Goosetrack via SMS in the field. The site will open in the fall of 2006 and offer information about geese as well as the tracking information.
