🚨 Master’s project!
Curious how birds find their way? 🧭🐦
Analyze decades of ringing data to study abnormal migratory routes and uncover what these deviations can reveal about the mechanisms guiding birds on their journeys. Drop me an email for details! #ornithology

Round trip complete! Spoonbill PRUNUS reached the Wadden Sea yday evening, and after mingling with the Spoonbills on Texel for the night, she arrived back at her Vlieland home this morning - 41 days since she left on her epic adventure! #ornithology

Even in summer, Doñana's flooded marshes sustain countless migrant birds from NW Europe.

Godwits en route to West Africa, and teenage Spoonbills 'oversummering' in Iberia made do with fish ponds & rice fields last few yrs. Now, they much prefer the marsh! #ornithology

Save the date! - NVG Annual meeting 2025 - 19-21 November 2025

The 2025 NVG meeting will be held from Wednesday November 19th to Friday November 21th in Egmond aan Zee, The Netherlands.

Details on registration, abstract submission and conference attendance grants for MSc students will follow.

What a beautiful map of our data! I just found this, very nice!

Cool study!

Tracks of 24 juvenile Spoonbills tagged in June 2025 in the Dutch Wadden Sea.

Tracks of adult Spoonbills in the Wadden Sea, including 14 individuals tagged in the 2025 breeding season.

Thanks to meticulous data management by @arnevaneerden.bsky.social, the 2025 Spoonbill cohort is now visible on globalflywaynetwork.org/tracks/speci...

Among them 24 juveniles (left) from 6 Wadden Sea islands. Follow along & discover how they establish routines in coming months! #ornithology

Wat leren we nog over lepelaars? Recent onderzoek geeft steeds meer inzicht in lepelaarlevens.

Prachtige bloemlezing uit het NL Lepelaaronderzoek.

Over de rol van ring- en zenderwerk in fundamenteel en toegepast onderzoek door Camilla en collega's (lowland-ecology.network), Tamar Lok (ecomoves.nl), werkgroeplepelaar.org en @globalflyway.bsky.social.

Wageningen Universiteit schrapt banen vanwege bezuinigingen De komende jaren verdwijnen er waarschijnlijk 130 tot 180 banen.

Binnenkort ook aan de WUR: bijltjesdag. Weer een ontzettend verdrietig gevolg van de onnodige bezuinigingen op hoger onderwijs en onderzoek van dit kabinet, gesteund door de destructieve oppositie van oa CDA, CU en SGP. Lekker gewerkt Eppo!

This seems like an appropriate time to remind decision makers of the comprehensive Ardea special on Great Cormorants which offers a clear evidence-baded response to calls for managing Cormorant by culling. #ornithology

De afgelopen dagen is een dikke golf #Lepelaars aangekomen in Nederland, en onder hen de #Waakvogels. Tot ver in het najaar zullen zij een schat aan informatie produceren over het Lepelaarleven in de Waddenzee. Kijk mee met de near real-time tracks via www.waakvogels.nl.

Pasen, dat betekent eieren zoeken. De eerste nesten gevonden op de Schiermonnikoogse kwelder voor ons @birdeyes-gfn.bsky.social onderzoek. Het paar van het voorste nest heeft er zin in: met maar liefst 5 eieren verwachten ze een succesvol broedseizoen!

Kijktip - vanavond om 20.25 uur op NPO 2 de documentaire De lepelaar in een roerige wereld van Hilco Jansma 📺

Hoogleraar trekvogelecologie Theunis Piersma adviseerde Jansma tijdens het maken van de documentaire, die laat zien hoe onze wereld verbonden is met die van lepelaars 🐦

De geringde grutto heet JOUKE SJOERDSPOLDER. In die polder in @gemeenteswf.bsky.social werd zij op 22 mei 2020 gevangen door @arnevaneerden.bsky.social, en geringd en gezenderd door Jos Hooijmeijer en @roelandbom.bsky.social. Vandaag gefilmd door Jouke Altenburg in rijstvelden van de Taag, Portugal.

Last week, 56,000 #btgodwits were counted in the rice fields of the #Tagus estuary, the highest concentration of the species in the EAF. In this rice field alone, 36K godwits were recorded by drone!

Read the paper in @amornith.bsky.social or the blog: americanornithology.org/balancing-ne... if you want to know if they have favourite tree species, avoid lesser noddy colonies, and have a specific height preferences (and more!).

We also found that females placed their nests near the territory border if their male neighbor is older than their partner. Could nest placement facilitate extra-pair matings?

A key finding was that pairs with helpers can take more risks. Pairs with helpers nested in food-rich areas, even with higher predator density. In contrast, pairs with helpers choose sites away from nest predators.

🐦🪺 How do birds select their nest-site? Simple question, but hard to answer. Our latest (my first authored 🎉) paper investigates how food availability, predator density, and helpers influence nest-site selection and nest survival in the Seychelles warbler.

When, where, and why so Spoonbills die? Thanks to volunteers all along the flyway the Dutch spoonbill research team @birdeyes-gfn.bsky.social is able to verify many cases.
Researcher Tamar Lok summarised the deaths from the 2024 autumn season in a brief report:

Wonderful! Could you add me as well?
