This report

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.

Black-tailed Godwit Demographic Project: Spring migration of Black-tailed Godwits in Iberia between 31 January and 24 February 2019

Publisher(s): University of Groningen, Global Flyway Network

Publication date: January 2020

Author(s): Jos Hooijmeijer, Egbert van der Velde, Bob Loos

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.

Meadowbirds on the horizon of southwest Friesland

Publisher(s): International Wader Study Group (IWSG)

Publication date: July 2019

Author(s): Ruth Howison, Heinrich Belting, Jennifer Smart, Mark Smart, Ole Thorup, Theunis Piersma, International Wader Study Group (IWSG)

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.

Describing habitat and finding colour rings of Black-tailed Godwits (Limosa limosa) in Doñana, Spain, from 3 – 10 October 2018

Publisher(s): Global Flyway Network

Publication date: January 2019

Author(s): Jos Hooijmeijer, Ruth Howison, Theunis Piersma

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.
