🚨 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

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

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.

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.

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.
