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

Here on the saltmarsh of Schiermonnikoog, #WaddenSea, #spoonbills are not that far advanced with breeding. Today an early fat big chick received a code-ring, 1st of season, as otherwise the birds are either settling, incubating or with very small chicks. https://t.co/33iBMkrrEM https://t.co/qaxna5w5B1 https://t.co/Zlo4FQ6BVm

Rosse #grutto vrouw JISP werd gezenderd in PWN bij VRS Castricum. Ze is nu aan het opvetten op het #Balgzand. De meeste rosse grutto's daar zijn overigens mannen, die oostelijker voor kust van #Wieringen slijkgarnaaltjes aan eten. Dat gedrag kenden we nog niet!

THE YEAR OF DETOURS!
After staging in #Brittany for 2 weeks, #Bijagós #whimbrel ORANGO is making an interesting 2nd detour to Iceland, now rounding #NorthSea. With low pressure system moving east, is it smart with winds?

In de steek gelaten door maatschappelijke partners, heeft @GlobalFlyway de financiële restjes bijeengeschraapt om te zorgen dat deze gezenderde rosse #grutto's toch kunnen blijven vertellen over toestand van wad & toendra. En U kunt het allemaal volgen op: https://t.co/1PU2SPD0Z9 https://t.co/UpJ6jaZw4o https://t.co/FGnii9xK3A

What a fantastically deep, and richly written, story on black-tailed #godwits #grutto's in #Bangladesh by Enam Ul Haque. He recognizes godwits as strong SENTINELS of our environment, e.g. indicating wide range effects of chemical pesticides & herbicides. https://t.co/KpM8cyZCjG https://t.co/gQHBayPmej https://t.co/ury4nvxAgn

In de tussentijd vertelt rosse #grutto HOORN, door @Jantienlc gezenderd losgelaten, waar het op het Terschellinger wad goed toeven is. Dat is vlak langs waddendijk, mooi in het zicht van rustige fietsers!
Ze zijn de WAAKVOGELS van onze omgeving.

Two of the red #knots recently tagged at Parc National du Banc d'Arguin in Mauritania are now in Parque Natural de la Bahia de Cádiz in Spain. Such stopovers remained pretty much undetected, and may herald new period of adjustment to rapidly changing environments faced by birds. https://t.co/JZtkATSo5B https://t.co/sKGff8qBCk

#Whimbrel ACUNO keeps surprising us!
After three weeks on the Faeroe Island completed northward #migration by flying to #Iceland after all! This adds the island habitats to the staging sites used across the #Atlantic. Where is ACUNO now going to breed? https://t.co/1PU2SPD0Z9 https://t.co/SpCCPy54vi https://t.co/AidSoQKcYz

#NZgodwits
The 2 satellite-tagged bar-tailed #godwits that we are still in touch with, 4BWWB & 4BBRW, have both left the shores of #YellowSea in South Korea. After crossing #Hokkaido, Japan, they began #flight across north #Pacific, en route to #Alaska.

Wat nog wel lukte was dat Joop Jukema & andere #wilsterflappers stug doorgingen met jaarlijks ringen van doortrekkende rosse #grutto's. Mocht er ooit steun voor uitwerking komen, dan valt te achterhalen hoe wadvogels die broeden op snelst opwarmende plek op Aarde daar mee omgaan. https://t.co/ZyDiqImRyQ https://t.co/FGnii9xK3A

AAN HUN LOT OVERGELATEN...
dat is inderdaad precies wat wadvogelonderzoekers die wilden helpen bij bescherming & beheer van #Waddenzee de afgelopen 6 jaar is overkomen. Geen steun, dus geen nieuwe kennis over veranderende wereld, geen perspectief voor jonge bevlogen wadecologen. https://t.co/hFFMZ0DPdR

BOUNTY! Wader research is very international, and we thoroughly enjoy & cherish our international collaborations. These 2 are @TijsenW & @DelipDasBisharg who together captured & satellite-tagged a black-tailed @godwit in @provfryslan & thus connected (godwits in) NL & Bangladesh. https://t.co/wrbq5sz6iy

TEICHOTT is niet alleen de naam van Imraguen vissersdorp in Parc National du Banc d'Arguin, het is ook een Afro-Siberische kanoet die door Team vanGils van @NIOZnieuws is uitgerust met tijdelijke satellietzender. Teichott maakt nu stop in de #Waddenzee, bij Koehool, Friesland. https://t.co/mqIgkcauIj https://t.co/nFBbuqs5sq

The #northward #migration of red #knots from @PNBancarguin towards #WaddenSea & beyond is now fully underway. TEICHOTT is ahead of the pack as it reached the (Dutch) part of Wadden Sea. Several others are making stops along the way. Follow excitement at: https://t.co/1PU2SPD0Z9 https://t.co/AFFqD7ab95 https://t.co/sKGff890KM

We are not quite sure what inspired, or motivated, the black-tailed #godwit born in southwest Friesland (see the code-flag), photographed by Egbert van der Velde of 'Team Skries' @univgroningen, but its SILLY WALK surely reminded some of us of Monty Python's Ministry! @JohnCleese https://t.co/wLSOKo2UcR

@WMBD @unep_aewa @BonnConvention @UNBonn @BirdLifeAfrica @BirdLifeEurope @BirdLife_Asia Just a question. Whilst I fully agree that light at night pollutes, what is published evidence that lights at night lead to disorientation in migrating shorebirds? Our tracked waders so far never showed obvious responses to e.g. cities. Thanks for evidence-based propaganda!

CRAZY FLIGHT BEFORE LANDING
Although #ruffs often do seemingly crazy things, the rumble-tumble flights of #waders were described for other species: https://t.co/XJ9Wvhn2Kp
Now co-author Ake Lindström photographed them in such a #flight on 18 April 2022 near Vombs Ängar, Sweden. https://t.co/iA0XzZOLmB https://t.co/v2EdxMTULk

What #whimbrels, and indeed bar-tailed #godwits, are missing!
Most have left Guinea-Bissau to do their seasonal #migration towards Iceland and Taymir, respectively, for sex, sociality & family businesses. Curious? See real-time tracks of some of them at https://t.co/1PU2SPD0Z9 https://t.co/RXpswKLYdW

Our old friend ABU, a #whimbrel tagged in #Bijagós in Guinea-Bissau 5 winters ago!, was 2nd to arrive on breeding grounds after stop in Ireland. ABU is an Icelander, whilst the 'winner' this year is ACUNO, a bird from Faeroe Islands. Watch it all unfold at https://t.co/1PU2SPD0Z9 https://t.co/Z4cUUIOC7a https://t.co/q0GOYXrt3e

Our dearest #spoonbill SINAGOTE is a valuable ambassador for migratory birds.

Nanpu, Bohai Bay, China.
This is 13th season of studying survival & turnover of red #knots during #migration. Due to covid lockdowns, Xiao Liu and his father, who started working with @GlobalFlyway as drivers many years ago, have to come to the rescue for the valuable resights!!! https://t.co/5aiwzlrgTS https://t.co/NtR3xVqFep
