🐦🪺 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.

🚨 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
