Satellite tracking of pink-footed goose

  FRAGILE Homepage  

On 31 March 2004, 7 pink-footed geese (Anser brachyrhynchus) equipped with satellite transmitters were released at Vest Stadil Fjord, Western Denmark. 3 of the satellite transmitters had built-in solar panels, witch can expand the transmitters lifetime to several years. The geese had been captured using cannon nets, and a total of 289 pink-footed geese were trapped. All geese were marked with standard metal rings and blue neck collars with three digit codes, which enable individual recognision in the field.

The pink-footed geese will leave Denmark in late April and migrate via Norwegian stopover sites in Trondheimsfjorden and Vesterålen to the Svalbard breeding grounds. Here they arrive in late May. Late September the geese migrate back to the wintering grounds in Denmark, the Netherlands and Belgium. You can follow the positions of the geese here (remember to set start- and end date):


The aim of the project is to track the detailed migration of the pink-footed geese and locate the pre-nesting sites used in Svalbard. Also, we wish to know preferred goose-habitats during summer and autumn in Svalbard. Important is also to know of staging periods in Svalbard. In 2004, likewise 2003, a team of scientists will study breeding ecology and behaviour.
The project is part of a larger project FRAGILE, FRagility of Arctic Goose habitat: Impacts of Land use, conservation and Elevated temperatur (, funded by the European Commission.
