This video shows Dr Maarten Loonen, Arctic tern researcher at Groningen university in the Netherlands. In Svalbard, he holds Arctic tern Guusje, the first tern provided with a geolocator in Dr Loonen’s Arctic tern migration research on Spitsbergen island. If the glue of the ring around Guusje’s leg will be dry, then she will be released, to (probably) travel all the way to the Antarctic, and back to the Arctic.
Of the 39 2013 geolocator Arctic terns, 13 individuals were caught again at the same nesting colony in Spitsbergen in 2014. The majority of the 2013 terns had not returned to the nesting site, as it suffered much from Arctic foxes stealing eggs.
The Arctic tern Beauty had already been ringed and provided with a geolocator in 2012; this bird was caught again in 2013, but not in 2014.
Names of the terns ringed in 2013 and recaptured in 2014: Anke, Benji, Henk de Groot, Inky, Jacobird, Jan Pier, Karmijn, Lubbe, Marjolein, Mystic, NoorDrenthe, Suzanne, Tom.
Names of the terns, ringed in 2013, and not caught again in 2014: Angelo, Annelies, Arctic Jewel, BenJeanette, Berna, Ellen, Flo, Frederico Segundo, Gerie, Gerrit de Veer, Guusje, Herman, Hidde, Imiqutailaq, Joanne, Jonathan, Krukel 1, Maamke, Maarten, Meliora, Riiser-Larsen, Ruth, SolarAccess, Stirns, Suzanne, Viti.
In 2014, also 18 Arctic terns nesting in Groningen province, in the Eemshaven harbour, in the Netherlands have been provided with geolocators.
This video by Maarten Loonen says about itself:
9 June 2013
I am joining Derick Hiemstra and Klaas van Dijk in the Eemshaven to observe and ring Arctic Terns. In this industrial area, activity is low and Arctic Terns have started breeding. On this location the world champions [in] migration distance were equipped with a geolocator two years ago and recaught one year ago. Today Derick and Klaas are doing their normal checks. They read colour rings but also metal rings from terns. Then we continue catching and ringing some breeding pairs. All this is part of my preparation for this summer field season on Spitsbergen.
20 Arctic terns nesting in the White Sea region in Russia got geolocators in 2014 as well.
