This website summarizes the work of researchers that are affiliated with the research groups of Theunis Piersma at the University of Groningen and the Royal NIOZ Netherlands Institute for Sea Research, and our many collaborators.

This map uses tracks of one bird in each flyway to take you along to where our projects on "tracking and tracing shorebirds" are hosted. Each flyway has a dedicate page where you will find more tracks and specific links [...] more

@waddentweets met 'economie' bedoelen jullie toch zeker 'korte termijn economie', want voor de lange termijn zijn weerbare biodiverse wadden juist erg nodig?

Een heel oud ambacht, grote passie, en met oud & jong op jaarvergadering in bovenzaal van Het Wapen van Baarderadeel in Jorwert nog steeds SPRINGLEVEND!

Heftig & ontroerend verhaal in @lc_nl over #trekvogel-onderzoek van boeren-professor Joop Jukema. Hindernissen die hij ondervindt om aan cultuur & wetenschap bij te kunnen dragen. Koppeling van werk van 'amateurs' & professionals is geheim achter >100 publicaties!

NARROW ESCAPE?
It was great to discover at https://t.co/baocug4ZOp that black-tailed #godwit SLINKEWEI managed to leave the Sahara coast again for a continued #migration to the #Tagus estuary, Portugal. This also illustrates, once more, the importance of this area! #grutto https://t.co/OoCz4OB9LG https://t.co/sC4GxcJfyk

BIOMONITORING! In new paper we show that prey ingestion rates of #spoonbills in #WaddenSea can be estimated from acceleration data. In this way spoonbills can directly essay spatial & temporal variation in availability of small fish & shrimp! #OpenAccess: https://t.co/PDULjGO8yP https://t.co/53JjNP1xzI

@ja_bakker @waarneming @Natuurmonument @vogelnieuws @Sovon @KeningGreide De kans is groot dat het bij deze vroegelingen om IJslandse grutto's gaat, Jorien. Voor het echte bewijs moet je dagelijks even naar deze website: https://t.co/baocug4ZOp
Kun je zien wanneer de eerste individuen echt vanuit de stopplaatsen in Portugal & Spanje naar ons toekomen.

The Frisian islands with Dutch Wadden Sea in foreground, looking east & northeast across German and Danish Parts of Wadden Sea, with the Siberian tundra in the distance (relevant as breeding area for a lot of birds using the foreground) made this NASA picture already much used. https://t.co/grklPJtfeM

Cool!
But: does #feather number goes up with body size?
In 1988 Piersma published figure for great crested #grebes, really counted and published in @ARDEA_journal. 14,000 rather than more than 20,000, even though the smaller grebes are always in water...

HOERA! maar de meesten zijn nog onderweg!
En het leuke is dat iedereen deze #grutto-trek vanuit de luie stoel kan volgen.
Klik op: https://t.co/baocug5xDX
Het gaat hier om grutto's met zenders die in Portugal, Spanje, Duitsland en Nederland zijn aangebracht. Leef met ze mee! https://t.co/bvik1EwzDG https://t.co/4Xu37PHF5z

Country-wide breeding distribution & home ranges of black-tailed #godwits (#grutto, national bird of NL) assessed in unbiased ways (using individuals tagged during staging in Iberia) shows how sparse suitable grassland has become.

The real-time online #tracking resource of @GlobalFlyway https://t.co/baocug5xDX nicely shows surge in #migration of black-tailed #godwits from wintering areas in West-Africa to staging areas in Portugal & Spain. Several tagged birds overfly Morocco and #Atlantic ocean right now. https://t.co/Huj1Gp0lPq https://t.co/sC4GxcJNnS

Magnifique. Le Guérande est très probablement l'endroit où notre #spoonbill SINAGOTE traîne en ce moment. Lisez à ce sujet l'édition française du livre qui porte ce nom : https://t.co/b3IgYX9Lb8

#SIBES stands for 'Synoptic Intertidal Benthic Surveys'. It is both a CONCEPT & many PROJECTS. E.g. every year @NIOZnieuws covers the entire Dutch #WaddenSea in a grid-based benthic survey. Great to see the concept applied in #SIBES_Formosa

In #migration from Guinea-Bissau to Iberia, having passed @PNBancarguin & Canary Islands, black-tailed #godwit SLINKEWEI made a U-turn to the coast of Morocco... Checking the #winds on 19 January shows it was facing head-winds of 50 km/hr. Fingers crossed!

ANIMAL CULTURES are a reality, but so far receive privileged acknowledgement for some charismatic mammals & the 'smart' birds (parrots & corvids). https://t.co/1chz6LQpts
Book on #SINAGOTE (a female #spoonbill) & friends, implies how #waterbirds also love, learn & work together. https://t.co/sEULw8PsSD https://t.co/hwVtDs9YK0

Wat een ongelooflijk rijke compilatie aan gegevens en verhalen en geschiedenissen over vogels, vogelmensen & biotopen in Zeeland! Gefeleciteerd noeste werkers. Heel leuk om hier en daar 'snippets' uit werk van @GlobalFlyway tegen te komen, zoals geringde 3teen & kanoet TenAlloul. https://t.co/DE1dYNhjbM
