Subadult Lesser Whitefroned Goose with transmitter (c) G. Müskens

To restock the decreasing breeding population of Lesser Whitefronted Geese in Sweden, Nordens Ark and Swedish Hunter foundation started to breed Leeser Whitefronts long time ago. In the beginning of 2000th complete breeding population was changed to birds of wild Russian origin. Now this breeding stock has increased and the Swedish collegues are able to release aroung 50 juvenile and subadult birds per year. In 2014 50 birds of the Russian-Swedish breeding stock were released at a moulting site in Lappland. Five of this were equipped with a satellite transmitter to follow their fate. Here you can see one of this geese migrating to the wintering grounds. To protect the breeding sites against disturbances we show only the movements of this birds starting mid of September.

Actual news from the Swedish Lesser Whitefronts

Our Swedish collegues present actual news about the Lesser Whitefronted goose migration and also field observations of the tracked birds on their website. For more information click here

Searching for Lesser Whitefronted Geese

While the breeding areas as well as the wintering sites in the Netherlands are still well know, we do not know anything about their migration routes and staging sites on autumn and spring migration. For this reason in this project we`ll catch some of the geese to equip them with GPS transmitters showing us more about migration routes, night roost and staging sites.

Goose catching - tricky to do this.....

To put on a transmitter on the back of the goose you have to catch them. This is even no simple job: geese are shy, skeptical and In march 20123 we failed when a snow storm came up. So we made another trail in the beginning of September at Hudiksval, north of Stockholm. During four days we observed the behaviour of the geese and studied their preferences. Then we put out a whoosh-net. During the morning when the geese were feeding on stubblefields outsite the town we tested our net six times. Unfortunatly when the geese sat in front of the net, this didn`t fly as it should and the geese escaped.

Catching at Sweden

We put out the net
and cover is with grass.
Barnacles came up in front of the net
and Lesser Whitefronts followed them.
The wildcam at the net shows the Barnacles,
but in the most important moment the net stuck!
