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

Bangladesh-tagged black-tailed #godwit SWAPAN flew round the clock, starting at dusk from lake near Shaliuhe, China, to make a beautiful 2000km long trek across the #Himalayas back to the nonbreeding grounds in coastal Bangladesh!

Everybody's back home in Bijagós!
#whimbrel ABU safely returned from breeding in Iceland to its Bijagós nonbreeding grounds, whilst ORANGO is getting close.
This completes yet another roundtrip of tagged #whimbrels - financially made possible by @MavaFdn in a project with @ibap. https://t.co/4bcsdODUu7 https://t.co/1uMIMbSWrP

Indeed, #whimbrel ABU passed the Parc National du Banc d'Arguin (@PNBancarguin) this morning, and may have stopped an hour or 2 at islet of Niroumi, a stronghold for whimbrel in this area (https://t.co/p6T51mB1BA). Keep an eye on ABU at https://t.co/1PU2SPD0Z9

Almost 5000km into its transAtlantic #migration, Bijagós-tagged #whimbrel ABU has reached relative 'safety' of the Sahara coast. Usually the birds carry on, without stopping at suitable #habitat like Banc d'Arguin, Mauritania. ORANGO underway too, passing Ireland. #flyway #flight https://t.co/cCGz7J7wz4 https://t.co/EY2XMFtLxp

Returning from Taymyr in late July, bar-tailed #godwit CAMINHATE stage on Lofoten island of Andoya for a long week, and then carried on along Norway coast & across North Sea to Dutch #WaddenSea. Welcome back here, Bijagós friend! Hope you find the food and safety you are after. https://t.co/p767xUdq25 https://t.co/juhgv6puN5

Yesterday,Iceland-breeding #whimbrel ABU crossed northeast Atlantic, picked up the smells or sights of Ireland (where it staged in spring), but now carries on across the big ocean stretch between Ireland and nrothwest Africa. Follow ABU to Guinea-Bissau? https://t.co/1PU2SPD0Z9 https://t.co/i7Ce75xD8t https://t.co/jRDmGcaASX

It is already mid August, but there are still black-tailed #godwits, #grutto's, #Uferschnepfe, travelling south. Yesterday IMKE, tagged as a breeding bird in UnterElbe, Germany, after staging on Ameland and often located in #WaddenSea, made the #track to Tagus, Portugal.

New paper in Bird Study @_BTO on #migration #flights of Dutch #Bitterns is available online: https://t.co/mPbeMnaxCU
Bitterns overfly the city of London and the Sahara! They may avoid too much flight, but they are certainly capable of it!

After a breeding season in Iceland, #whimbrel ACUNO returned to the shores of Amrumai on the island of Maio in the Bijagós Archipelago, Guinea-Bissau, where FORMOSA is exploring various sites in the south of Orango National Park. See 4 yourself? https://t.co/1PU2SPD0Z9

This bar-tailed #godwit belongs to @NIOZnieuws scheme. It was ringed by Joop Jukema on island of Terschelling in Wadden Sea on 21 May 2022 as an adult male with code N8RRGG. Note that in picture, the black (N) flag is just about visible. This is 1st observation after ringing. https://t.co/uRvJq1VNOp https://t.co/bVoIQXOBwF

We trust that most of you had already discovered that the #whimbrel called FORMOSA safely returned to island of Orango in the Bijagós, Guinea-Bisau. In this time ACUNO got close too, after almost 6000 km of nonstop flying from Iceland - across north #Atlantic. #migration #flyway https://t.co/sW3P5ir3ZW https://t.co/cbFGNUlbY3

We don't think that it is justified to approximate prey availability (for insectivorous birds) by vegetation growth!
The arguments that this is much too big a step are developed in Editorial in @ARDEA_journal on the 'Drent principles'. Read here & see https://t.co/Wd12RYRRFd https://t.co/nYEmIWa87z https://t.co/TMmIaokjND

With #whimbrel FORMOSA flying at night offshore Mauritania (west of @PNBancarguin) 6000 km into the #flight to #Bijagós @ibapgbissau, ACUNO also left Iceland for what will likely be a similar nonstop flight to Guinea-Bissau. #migration #flyway @eco_flyway

The Plot Thickens!
New #openaccess study by Monteiro et al https://t.co/nud9vV1IXW shows that across Europe, abundance of ground-active arthropods increases with vegetation productivity, but other potential prey don't show such trends.
Key: What do wader chicks eat, when, where? https://t.co/QYVe0vydau
