Colour-ring readers jave contributed greatly to the science underpinning 1️⃣0️⃣ years of WaderTales blogs. One of the best studies, in terms of feedback to observers, is the Sanderling project run by @jeroen-reneerkens.bsky.social. More here: wadertales.wordpress.com/2019/10/04/t... #ornithology

This month, WaderTales will be ten years old. I'm going to create a thread that highlights some of the research findings that have surprised me. Plenty of "Wow!" & "I didn't know that!" moments. Here's a link to the catalogue of 150 blogs wadertales.wordpress.com/about/ #ornithology

It is juvenile #Sanderling time! Observers, please share your counts of adults and juveniles with me ([email protected]; do not use the address in ageing guide!). I will use them in population models to. 📄 Find the ageing guide here: bit.ly/3HQdb5M

Sanderling. Just a few weeks old. Imagine arriving in St Andrews, from Greenland. Should you stay? Or fly to England, Portugal, Mauritania or Namibia? Where's best? If only this bird could read: wadertales.wordpress.com/2019/10/04/t... #ornithology @jeroen-reneerkens.bsky.social

I recommend the well-illustrated blog post by Alaska Audubon on our recent paper in Global Change Biology led by Eveling Tavera Fernandez and Kirsty Gurney about the effects of climatic variation on timing of nesting in arctic shorebirds. ak.audubon.org/news/arctic-...

Shorebird chicks are hatching here in Greenland! This year, egg predation has been intense, especially on Turnstone clutches, so every successful hatch feels extra special. This Turnstone male brooded its four chicks right next to my phone. A bit too close maybe...

#sanderling copulation is a balance act. It always ends with the male fiercely pecking the neck feathers of the female. I have no clue why.

Are you joining us in Groningen? This year's conference will be in The Netherlands 🇳🇱 #IWSG2025 Registration closes 30th June Details here ⬇️ www.waderstudygroup.org/conferences/...

In NE Greenland today, I watched a male Sanderling give his all to impress a female-- song and calls, slowmotion dive and nest scraping. She was not impressed and calmly kept foraging. #shorebirds never cease to amaze.

WAT HEBBEN WE ONZE GROND AANGEDAAN? Eerder vonden onderzoekers van www.birdeyes.org hoge concentraties #PFAS in levers van #grutto's, vooral in broeders kruidenrijke weilanden (www.sciencedirect.com/science/arti...). Ook eieren blijken rijk bedeeld. Het schadelijke PFAS zit dus inmiddels overal.

Millions of birds nest in the Arctic each year. But did you know they’ve been doing this since the Cretaceous? Can’t believe I finally get to share that our paper on the birds of the Prince Creek Formation is out in ‪@science.org (and on the cover)! 🧵 Art: Gabriel Ugueto ‪@serpenillus.bsky.social

The best welcome in a new house I ever got....

Sanderling flocks - passing through! wadertales.wordpress.com/2019/10/04/t... Research by @jeroen-reneerkens.bsky.social #ornithology

Seen a Sanderling recently? Some of the birds in the UK in May will have left Namibia, flown north along the Atlantic cost and crossed the Sahara. Long way still to go to get to Greenland! More here: wadertales.wordpress.com/2019/10/04/t... Research: @jeroen-reneerkens.bsky.social #UKbirding

Latest WaderTales blog reviews what we are learning from tracked waders/shorebirds: wadertales.wordpress.com/2025/05/06/m... But are researchers making full use of the data that birds collect for them? #ConservationScience🌍

Migratory Birds Advance Spring Arrival and Egg‐Laying in the Arctic, Mostly by Travelling Faster 📄

In May, lots of waders are still migrating through UK/Ireland. Sanderling from Africa and heading for Greenland. Many will stop off in the UK to refuel. Blog based on fascinating research by @jeroen-reneerkens.bsky.social wadertales.wordpress.com/2019/10/04/t... #ornithology

📄 New Paper! Migratory Birds Advance Spring Arrival and Egg-Laying in the Arctic, Mostly by Travelling Faster doi.org/10.1111/gcb.... @globalchangebio.bsky.social @mpi-animalbehav.bsky.social @animaltracking.bsky.social

🚨Publication in @globalchangebio.bsky.social by Lameris et al. → Early snowmelt = earlier egg-laying, but only 2 waterfowl arrived earlier. → Over time, most arrived earlier—regardless of snowmelt or laying. → Why? Faster migration: shorter stopovers = earlier arrival. 🔗 doi.org/10.1111/gcb....

Every year, fewer #WhiteStorks cross the Straits of Gibraltar on their annual migratory journey. In this paper, we unveil the mechanisms driving the recent and rapid loss of their migratory behaviour. 👉https://besjournals.onlinelibrary.wiley.com/doi/pdf/10.1111/1365-2656.70035

Our milestone #SIBES publication is out! We describe methods and share data of this huge sampling effort. We hope it will stimulate research, forge collaborations, and allow evidence-based management of the UNESCO #waddensea. Read the paper here: www.nature.com/articles/s41... #macrozoobenthos

We've reached 1.5°C global warming. With current policies, we're heading for a catastrophic 2.7°C warming. A new review paper in Science shows: this would change the Arctic 'beyond recognition', with knock-on effects (like rising seas) around the world. 🌊 www.science.org/doi/10.1126/...

This Registered Report masterpiece just dropped at BMC Biology, brilliantly led by a great team with the help of 300+ analysts & reviewers Same question, same data: go figure! tl;dr: Substantial heterogeneity among results comes from differences among analytical choices 🔗 doi.org/10.1186/s129...

There are many studies of phenology of components of the tri-trophic tree-insect-bird system, a useful model for understanding effects of climate change. But how do different measures relate to each other? We compared 5 methods, deriving 9 metrics, across 6 tree spp www.biorxiv.org/content/10.1...

Exciting personal news! 🎉 From March 1st, I'll start as a tenure-track researcher in Arctic avian ecology at Aarhus University. 🐦❄️ I’ll continue my fieldwork in @zackenberg.bsky.social Greenland and embark on new adventures in Svalbard. Can’t wait to get started! #ArcticEcology #ornithology

Out in @animalecology.bsky.social and open access, this beauty showing that older common terns navigate more efficiently than younger ones and that efficient navigation leads to a reduced migration duration and earlier arrival at the breeding and wintering grounds: doi.org/10.1111/1365...

New paper out in @rsocpublishing.bsky.social! Research from our group shows that males of the polygynous ruff visit many potential breeding sites within a breeding season, travelling up to 9000 km and visiting up to 23 different sites! royalsocietypublishing.org/doi/10.1098/... 1/7

Some polygamous birds blur the classic pattern of birds migrating at the end of the breeding season. Ruff males (without parental care) may visit multiple breeding sites throughout the species' range in the same year. 👇 Marked birds in the Netherlands. royalsocietypublishing.org/doi/10.1098/...

1/5 Nieuwe analyse: slechts 10 procent van de onderwaternatuur in de Waddenzee wordt effectief beschermd. Beschermingsmaatregelen zijn bovendien vaak op de verkeerde plekken gericht, volgens onderzoek geleid door @kasperjmeijer.bsky.social van @unigroningen.bsky.social 🧵
