An international expedition team, with amongst others goose researchers Helmut Kruckenberg and Gerard Müskens, visited the island of Kolguyev in the Barents Sea in August 2016. They fitted 18 white-fronted geese with white GPS-neckbands with a black 2-digit code. Three of these ‘white white-fronts’ have been observed in the Netherlands, while two others were seen in Germany. Remarkably, the first observation of one of these birds was actually...

Until 2013 many have wondered what the origin is of the ever increasing numbers of moulting ruddy shelducks on the Eemmeer in the Netherlands. During recent years up to 800 birds were present. Other areas (IJsselmonding and Lauwersmeer) have also seen increasing numbers of moulting ruddy shelducks. The origin of these birds is unknown. It was always assumed that they were escaped birds from private waterfowl collections and their offspring....

Verzoek om witte halsbanden bij kolganzen zo snel mogelijk in te voeren   Deze zomer (2013) zijn op Kolguyev in Rusland 70 jonge kolganzen en hun ouders uitgerust met witte halsbanden met drie cijfers erop. In deze halsbanden zitten GPS loggers om te bestuderen hoe ganzenfamilies trekken. De GPS gegevens moeten met een speciale ontvanger uitgelezen worden op een afstand van een paar honderd...

Pink-footed geese have been neckbanded in 2012 in Denmark (March) and Svalbard (August). During the spring of 2012 we attemted to catch pinkfeets, as usual, in the Vest Stadil Fjord in Denmark. Unfortunately, the numbers caught where low (39 pink-footed geese were fitted with white neckbands). This was, among other things, due to the large and still increasing number of barnacle geese that are present in the area during recent years. We are on...

Since December 2005 a new ringing programme of Bewick’s Swans runs in the Netherlands. Part of the birds is equipped with yellow collars with built-in GPS loggers (see picture). These loggers regularly record geographical locations of these birds. This should yield information about their habitat use in winter, and how this carries over to their performance during spring migration and in the breeding season. The logged data can be...
