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

Last week @GlobalFlyway lost its oldest & most ardent supporter.
Thank you MAVIS RUSSELL for >25 years of hard work, encouragement & abundant good vibes!
Plenty of memories to be shared. Look at her, 75y old, in pink pants during neap-tide mud game at 80Mile Beach in Oct 1999! https://t.co/7EvoJLKOTa

IS DIT IT?
DIT IS IT!
sei Teade de Boer, en stjoerde ús op wei!

De kuiertocht yn 't tsjuster oer it boerelân by Wommels wie in geweldige ofslúting fan it projekt ‘Oer de râne fan de tiid’ om 75 jier Fûgelwacht Wommels te fieren.

Marten Winters betocht it útropfraachteken. https://t.co/UVZjRntNgG https://t.co/9bYVINCVQJ

With the whole world as its witness (https://t.co/h0yuMmdZNa), bar-tailed #godwit 4BBRW made it to New Zealand, the missing part of its track showing that #flight across #Pacific took longer than a week. Missing bit of track is now filled by 4BWWB who is 4000km into #migration. https://t.co/9REfnL88Vp https://t.co/wN0vmV7rOf

Yesterday, @GlobalFlyway was witness to symposium on 'Milestones in migration research' (as part of annual conference of @DOrnitholGes), celebrating the life & work of Prof. FRANZ BAIRLEIN in word and deeds! With a heart-warming appearance of team of 'Vogelwarte Wilhelmshaven'. https://t.co/OSqlPPYYxB

Bar-tailed #godwit 4BBRW touched Fiji in #flight, but certainly not on land & nicely continued his flight for last 1000km or so to Pukorokoro-Miranda @miranda_trust in New Zealand. Keep on eye on him at https://t.co/h0yuMmdZNa

In addition to adult bar-tailed #godwits that can be seen @globalflyway, youngsters were tagged, which are now showing how long-distance #migration is learned in life. Adrian Riegen from @miranda_trust summarizes movements in their 3rd year in latest PMNews issue! https://t.co/nooXEDMtbM https://t.co/BcucfH5WLL

AGREE!!!
And for a summary account of what all this amazing #endurance & #navigation means for advancing our understanding of #migration and #biology in a more general sense, see our big review in #Ornithology (@AmOrnith): https://t.co/mnCJVq2r1O

New paper on limits to food intake in red #knots: #sulfur. This happens @PNBancarguin when knots eat a small bivalve called Loripes that hosts endosymbiotic (!) chemoautotrophic (!) bacteria. Knots eat more when sulfur load is less, and can get accustomed. https://t.co/QpWChLykqx https://t.co/Un65ujmUpQ

SO FAR, SO GOOD!
Bar-tailed #godwit 4BBRW is now flying 500km to west of Hawaii. This is about 5000km into its #migration from Yukon-Kuskokwim Delta, #Alaska, to Miranda, New Zealand. Witness this epic #flight performance yourself at: https://t.co/h0yuMmexCI

YES! One of our 2 satellite-tagged bar-tailed #godwits from New Zealand called 4BBFRW is off, and on his way across the mighty #Pacific! Departure date is a few days earlier than before, as he left on 19 Sep in 2020 and on 17 Sep in 2021. Have a smooth flight! #flyway https://t.co/qbR0Pd7hD5 https://t.co/xdC8KXJMU1

Met de (trek)vogels gaat het een stuk minder... en we weten maar nauwelijks waarom!

Waarom?

This is interesting, as CLJ 'ended up' in its 2nd or possibly 3rd yr of life, as a 'winterer' at Miranda, Firth of Thames, New Zealand winterer. In fact, it was just seen there (on 3 Sep) by Tony Habraken. Early arrival in NZ this year suggests CLJ arrived direct from Alaska. https://t.co/ZdiBuVmJdI

Indeed, for some earlier (now published) work on another Numeniinid, the black-tailed #godwit, see latest paper by Mo Verhoeven et al. in @AnimalEcology: https://t.co/owLDj6V2CW
