De vinger aan de pols van de grutto populatie met een actueel overzicht van de demografische parameters op basis van langjarig veldonderzoek in Súdwest Fryslân
A complete database of research publications and outreach, produced under supervision and in collaboration with the Rudi Drent Chair in Global Flyway Ecology, both at the University of Groningen (RuG) and Royal Netherlands Institute for Sea Research (NIOZ), can be found here. This online overview covers peer-reviewed papers, books, book chapters etc.
From 1 – 8 March 2020 we visited areas in Parque Natural de l’Albufera, southeast of Valencia. We recorded resightings of individual birds and described godwit habitat. In this report we present a daily overview of our findings with photos, locations we visited, numbers present and the first conclusions and recommendations. We thank Nacho Dies for his coordination skills and help with access to the Raco de l’Olla reserve; thanks to Javier Jiménez Romo for access to Tancat de Milia.
The team monitored in Portugal (Sado & Tejo) and Spain (Doñana & Extremadura), collecting lots of information on numbers and conditions. February 2019 was much wetter than 2018 with equal maximum numbers in Portugal (40.000!), slightly more in Extremadura and many more in Doñana. They are doing a pretty good job out there with an estimated 65% of all ringed birds seen! Enjoy the read! And the pictures…

Between 23 October and 5 November 2019 the GFN team visited the most import areas in the Senegal River valley in both Senegal and Mauritania from Djoudj and Diawling NP all the way inland towards Kaédi and beyond Lake Aleg (Brakna region) to record resightings of individual birds and describe godwit habitat. In this report we present a daily overview of our findings with photos, locations we visited, numbers present and the first conclusions and recommendations.

he team visited the most import areas in the Senegal River delta and Djoudj NP Northern Senegal to record resightings of individual birds and describe godwit habitat. This report gives daily overviews of their findings with photos, locations visited, numbers present and the first conclusions and recommendations.
Harvesting international ecological knowledge to connect farming practices in the southwest of Friesland with biodiversity.
In the low countries of Europe, the downsides of industrial agriculture have been highlighted by the rampant loss of farmland birds, some of the most enigmatic of which are waders. The International Wader Study Group (IWSG) has played its role by first summarizing the ever declining numbers of breeding waders in Europe. In an attempt to be upbeat rather than the usual ‘depressed’, the IWSG international workshop in Workum, Friesland, The Netherlands on 28 September 2018 took an idealistic approach. We put all the work on our disappearing breeding waders to good use in the design of ideal landscapes with various species of meadowbirdson the horizon!
The book is bilingual, in English and Dutch. The Dutch title is called “Een horizon vol weidevogels“: Internationale ecologische kennis die de landbouw in Zuidwest-Friesland met biodiversiteit verbindt.
The GFN team visited areas in Morocco previously identified as godwit areas, as well as new areas that showed up as hotspots from the accumulated transmitter locations.
After the breeding season Black-tailed Godwits migrate to southern Europe (Spain and Portugal) and West-Africa where they stay for wintering. This expedition is part of our mission to get a good overview of the wintering grounds, resighting conditions, local facilities and knowledge and to make a start with setting up a dataset of individually recognizable godwits that winter in these areas, including habitat and prey choice. At this moment comparable research is done in NP Doñana (Spain), Extremadura (Spain) and the Tejo/Sado estuaries near Lisbon (Portugal). The report includes detailed re-sighting reports of each observed colour-marked Black-tailed Godwit.
