Aan het eind van het winterganzenseizoen 2016/2017 zijn op 10 mei jl. door Gerard Muskens c.s. met het kanonnet 23 Rotganzen op Terschelling  gevangen en geringd. Veertien rotjes kregen de al langer in gebruik zijnde rood-zwart (R.N.) ringen. Negen exemplaren zijn geringd met de nieuwe kleurringcombinatie lime-groen (L.G.). Omdat de aanwezige kleine groep rotjes op één dier na in zijn geheel werd  gevangen, is het aannemelijk dat het 8...

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...

The barnacle goose population wintering in western Europe has increased markedly during the past decades. They also stay much longer on the wintering grounds in spring. Barnacle geese breeding in Arctic Russia may stay in the Netherlands and Germany up to mid May, before flying almost non-stop to their norther breeding grounds. Howver, there are also individuals that leave much earlier, and use stopoer sites in the baltic area before oving...

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...
