New Video: Kolguev 2019

During summer 2019 Russian, Dutch and German researchers again returned to Kolguev Island placed in the arctic Barents Sea. A whole summer they studied breeding biology of waders, ducks and geese. This year we produced a video about our work and the island itself. Visit the "island of geese"here.

Where do Curlews from NW Germany winter?

Equipped with a backpacked tag we`ll find out migration routes of Curlews.

Curlews are listed as a threatened meadowbird species in Germany. During winter they migrate to warmer sites along the Atlantic coast between West Africa and UK. Where in detail birds from NW German breeding population winter, is actually unknown. To determine this sites in details we tagged 42 birds during breeding season in 2020. This project is done in a joined project with University of Osnabrueck and financed by Federal Nature Conversation Agency of Germany, Lower Saxony Waddensea Foundation and administration of Landkreis Aurich. Due to the conservation permission we will not show the breeding sites and movements during breeding period, but all movement of migrating birds can be followed live on our website. Click here .

Follow tagged Greylag geese

Collar with integrated GPS tag

Within several projects we tagged Greylag geese with high resolution GPS tags in The Netherlands, Germany, Sweden, Norway and Lithunia. You can follow the migration of this geese by our webtool here. Greylags were reintroduced in western Germany and The Netherlands from 1960-1980th. The population does well and recovers in more or less all suitable places now. To find out more about the breeding biology and migration of this population we caught Greylag families and moulting geese and banded them. Some of them got collars with integrated GPS-transmitters collecting position, height, speed and behavioural data (ACC).

New: German newsletter for birders

First time we piublished a newsletter for goose watchers and other nature friends to inform about scientific projects, preliminary results and other interesting things around migratory birds. This newsletter is held in German language and can be downloaded on this website.

We`re looking for students who like to work in the field

Student jobs

During the next field season we can offer some themes for students bachelor-, master- or Phd-works on Kolguev and in on the staging sites in northern Germany. In cooperation with Institute for Avian Research, Wilhelmshaven, we'll continue our work in the arctic in 2012. Read more hier.

new book: Migratory birds in the Wadden Sea

Lots of people like to observe migratory birds on their way. By this yearly migration they achieve enormous things. The wadden sea area is stepping stone for millions of migratory birds which partly breed thousands of kilometers north and fly to africa or further south for wintering. This book, edited by Peter Südbeck, Franz Bairlein and Reno Lottmann, presents stories about this wonder and the reason why we have to protect this special kind of nature.

How to catch wild geese

How to catch wild geese in winter? In The Netherlands there is a very old tradition based on the mediaval. Goose catchers used trained decoys and clapping nets. Kees Polderdijk, one of the active goose catchers, presents how to catch in this Dutch video. Click here.

2012: NABU project: research and protection of Lesser Whitefronted Geese in Germany

The Lesser Whitefronted Goose is the most threatened goose species in Eurasia. The population decreased during the last 40 years dramatically. So, nowadays just app. 90 birds survived in Scandinavia. The wintering grounds of the Lesser Whitefronted Geese are places in Hungary, Greece, Bulgaria up to Iraq, but also a part of the population is wintering in western Europe. Well known wintering sites are Petten and oude Land von Strijen in The Netherlands. On the other hand data beginnin 1900/01 show staging adn probably wintering Lesser Whitefronts in Northern Germany as well. So, one target of the new project of BirdLife Germany is to find the stepping stone and wintering sites in Northern Germany. More information you'll find here.
