Great day exploring the hills around Sempach ahead of a work visit to @vogelwarte.bsky.social. Good practice wt woodland birds of which I've seen very little since moving to Fryslan few yrs ago. Lovely soundscape wt whistling Red Kite, croaking Ravens, ticking Hawfinch, rattling of Mistle Thrush...

The meadows still have to flood, but the winter bird community at Blaugerzen is starting to form. The first Barnacle and White-fronted Geese are back, and mixed flocks of Lapwing, Starling and Golden Plover are on the fields again. They'll define the birding scene for next five months. #birding

1.5 MILLION RAPTORS! 🦅🤯 For the first time in BRC history, we have recorded a staggering 1.5 million raptors in a single autumn season — a true milestone after 17 years of counting! Read more here: www.batumiraptorcount.org/brc17/2025/10/15-million-raptors #ornithology #RaptorResearch

Over the past 2 weeks, no less than 10 Dutch GPS-#Spoonbills made the crossing from Iberia to Africa. They did so in classic Spoonbill fashion by starting the ocean-crossing near Cadiz, rather than taking the Strait of Gibraltar. 1/2 #ornithology www.globalflywaynetwork.org/tracks/speci...

GREAT DAY FOR EEL CONSERVATION The Basque Country is the craddle of glass eel consumption Today, the Basque Government has announced a ban on glass eel fishing due to eel's critical situation Similar movements needed in Spanish @miteco.gob.es and EU @ec.europa.eu www.eldiario.es/euskadi/gobi...

170.000 RAPTORS IN ONE DAY! After yesterday’s heavy rain and a quiet morning, today the sky exploded with Steppe Buzzards and large eagles! Continuing from 10 am until almost the end of the count. At some point, we counted over 14.000 raptors in less than 20 minutes. THAT'S BATUMI! #ornithology

After a super intense week with a back-to-back Spoonbill and Wader Study conference, its time to shift to lower gear for a bit. Starting the day with a slow stroll through the fog at Griene Dyk. Hoping for a Yellow-browed Warbler among the plentiful Gold- and Firecrests. #birding

After the thrill of reaching the million, we went straight to the peak of diversity. The challenge of counting high numbers of birds slowly shifted into identifying the (relatively) fewer but more difficult ones: the large eagle species! But they also brought a special guest along...👇 1/2

Thank you to all of today's speakers for a really interesting array of talks! So much great research, and more on the way tomorrow! #IWSG2025 #waders #shorebirds #ornithology

What an honour to open the 50th @waderstudy.bsky.social conference with a plenary on Spoonbill migration culture on the beautiful stage of DOT in Groningen. The Spoonbill-inspired concerto 'Solanum' by Tjibbe Stelwagen and Caspar Kootstra made for a perfect tandem wt the arts. #ornithology

We're got a variety of great talks at our conference today, with topics including... 👥️ Population development 💧 Resource use ☀️ Responses to environmental change 🪱 Foraging ecology and diet #IWSG2025 #waders #shorebirds #Ornithology

Here we go then! Our 50th annual conference is officially open 🥳 #IWSG2025

A vagrant juvenile Sanderling turned up in Israel—likely after a single non-stop flight from the Dutch Wadden Sea. Here’s thread explaining why that’s remarkable and interesting. @wadertales.bsky.social @globalflyway.bsky.social #Birds #Migration

A dramatic end for an ambitious Spoonbill. Yday morning LAYLA crashed into the ocean just offshore Madeira, 56h after departing from the Wadden Sea. She rested barely 7h even though she found nice Spoonbill hotspots on the way. Poor choices... #ornithology www.globalflywaynetwork.org/tracks/speci...

A true Bluesky — filled with raptors! After days of rain, we were greeted by a bright, blue, cloudless sky this morning! The result? Thousands of birds and a high species diversity. With the main message: the eagles are coming! Stay tuned for more! For daily totals: www.batumiraptorcount.org/data

The www.BirdEyes.org team is thrilled to announce a new paper by Mohamed Henriques showing how Spoonbills change space use over the course of their summer stay in the eastern Dutch Wadden Sea. After breeding, many adults converge in the Lutjewad area. #ornithology www.birdeyes.org/lutjewad-amo...

Yday >1900 #Spoonbills left 🇳🇱 via the watch-site at Cadzand! Among them were 4 GPS-birds that departed from the Delta, including LUNA who met PLUK in flight over Ostend (🇧🇪). Meanwhile, TAAS and HIDDE jointly flew from Balgzand to the Delta. #ornithology www.globalflywaynetwork.org/tracks/speci...

Astounding for the @batumiraptorcount.org crew to reach the 1 million milestone so early in the season. 😳 Congrats to all volunteers and flyway trainees, expertly led by the first ever all-women coordinating team: Eva Drukker, Elien Hoekstra and Mitra Daneshvar. Celebrations are in order! 🤩

This achievement was only possible thanks to our amazing and hard-working team – counters, trainees, coordinators – and our wonderful host families for their endless hospitality. Check out our daily counts and news flashes here: www.batumiraptorcount.org/data 2/2

A Goshawk managed to catch a Snipe at Blaugerzen the other day. Then got the attention of one, two, three Marsh Harriers. In the squabble, a juvenile harrier was eventually able to claim the prey for itself. #birding

Had a privilege and pleasure to teach terra pkg (created by @roberthijmans.bsky.social et al.) and spatial sampling with R together with Alexandre Wadoux at the #EOSummerSchool2025 at WICC. You can follow the terra tutorial from here: differ.blog/p/processing... 📹: youtu.be/q9sQkg7BeAc?...

The Honey Buzzards keep on coming! With another 50K+ counted today, we’ve now passed half a million HBs this season! Rising numbers of Black Kites — as their peak is still ahead — pushed our overall total past 700K! And it’s not just the bulk species 👇 #ornithology 📸Eduardo C. Wals 1/2

🚨 Calling researchers, students, technicians in cognition 🚨 We’re running a 10-min anonymous survey on how animal cognition is defined and studied across disciplines (from ecology, ethology, psychology, neurology, etc). 🧠✨ Scan the QR code & share widely #AnimalCognition #ResearchSurvey #Science

Foremost, we found it an exciting experience to publish our scientific debate in such a public manner, and thank @moveandconserve.bsky.social and co-authors for the constructive and cordial discussion! Exciting times ahead — only together can we connect birds, people & places across the flyway!

A new study led by @moveandconserve.bsky.social used GPS tracking to test the monitoring potential of Eilat and Batumi. An invaluable step toward linking counted birds to their origins, but we found it needed some elaboration from a migration count perspective! Our commentary: tinyurl.com/nnbzu7kc

The first week of September is barely behind us and already the impressive volunteer crew of @batumiraptorcount.org has tallied over half a million raptors making their way south along the eastern Black Sea coast. #ornithology

We are experiencing a particularly exciting season so far! For example, we've counted exceptionally high numbers of Short-toed Eagles, Marsh Harriers, and Black Kites! Meanwhile, we're not even halfway through the season yet, with still so much to come. 2/3 Photos by Eduardo C. Wals & Paul Buntfuß

Luckily, we have a great team of counters, trainees, and coordinators to count and identify the many thousands of raptors heading their way! Make sure to check out our daily count updates and season totals here: www.batumiraptorcount.org/data Stay tuned for more news from #BRC17! 3/3

Science as a conversation: In January, we published a paper about migratory bird counts www.sciencedirect.com/science/arti... For different reasons, we did not include the managers of the bird counts. But the @batumiraptorcount.org people had some important comments #conservation #ornithology 🧪🐾🌎

Ten days ago #Whimbrel LYTSE GRIENE went off radar after many weeks in Cádiz. A sign the bird had continued south, confirmed a few days later: after a 50+h flight to Guinea-Bissau, and a 5day stop in Liberia, he made it all the way to Ghana! #ornithology www.globalflywaynetwork.org/tracks/speci...

Migration is a go! Yday 3 @globalflyway.bsky.social GPS-Spoonbills flew from 🇳🇱 to 🇫🇷. Among them were adults MIGUEL (orange) and STERN (purple) who met each other in flight at noon, and then flew together for 9h until they split up again south of Le Havre. www.globalflywaynetwork.org/tracks/speci...

Zelden zag ik een motie die zó helder laat zien in wat voor zieke tijden we leven en wat er deze herfst op het spel staat

What a great and welcoming community at #BESMove2025! Was a real pleasure to share a cultural perspective on #bird #migration based on field and tracking studies of raptors and shorebirds.

We're kicking off day 2 of our annual meeting with a plenary by @wmgvs.bsky.social on raptor and seabird migration #BESMove2025

After staging at the Russian-Finnish border near Varanger for 12 days, #Whimbrel GRUTTE GRIENE departed southward in the evening of Aug 17, averaging 66km/h to reach Arcachon (SW France) in the early hours of Aug 20. Over France the bird consistently cruised at 4-5km above sea level. #ornithology

Crappy pics in enerving times. A juv Red-footed Falcon has been staging at my local patch for two days along with a notable influx of Wheatears. This morning a quick stop at the lake shore en route to the office yielded an Osprey and two nice flocks of Spoonbill heading south. #Migration! #birding

Managed a proper count of the Great Egret roost at Mardyk, Sneekermeer, yday evening wt a fellow birder. A total of 167 Egrets. Most arrived from min bf till 15 min after sunset. At the peak 40 Egrets arived in a 5 min window. Curious how this will develop towards the Egret peak in October! #birding

Being Heron is complicated - for a youngster there are so many skills to learn to simply stay alive. Learn as much from your parent while you can.

Wasn't quite sure what to make of this odd cloud formation at Blaugerzen yday evening, but it was hard to miss. Turns out to be a fallstreak hole aka 'hole punch cloud'. The cloud was noticed and photographed by many folks for miles around. Stuff of legends. 🤭 en.m.wikipedia.org/wiki/Fallstr...

The vole population around Sneekermeer has been exploding lately. One can tell as much from the huge number of mice-eaters like Great Egret roaming the fields. This evening no less than 150 Egrets came to roost at Mardyk. Overall there may be 200+ Egrets in Sneekermeer area atm! #ornithology

Very proud of @meixu-cm.bsky.social who just released a pre-print of her MSc research, showing how Eleonora's falcons negotiate prevailing winds and use islands to cross the Indian Ocean. A neat collaboration with Laura Gangoso et al from @ebdonana.bsky.social. #ornithology doi.org/10.1101/2025...
