Since 2009 I’m working as a technician at the NIOZ Royal Netherlands Institute for Sea Research in the Coastal Systems department. I live in the beautiful town of Oosterend on the island of Texel, close to mudflats of the Wadden Sea.
I coordinate the colour- ringing of Bar-tailed Godwits and Red knots in the Wadden Sea and on the Banc d’Arguin, Mauritania. I’m therefore involved in catching shorebirds, and I spent a lot of time on the mudflats for ring reading and sampling.
Besides the work on shorebird movements and demography, I’m working on their prey, the intertidal macro zoo benthos, as one of the team members in the SIBES project. During each summer since 2008 we sample the entirety of the intertidal mudflats of the Dutch Wadden Sea and process all these samples in our lab facility at the NIOZ. I’m also one of the experts in species identification and taxonomy of benthic species. For Dutch readers, see also Basismonitoring Wadden.
In the months of the year that Red Knots and Bar-tailed Godwits are present in the Wadden Sea, we’re catching with mistnets, on the island of Griend or the sandbank Richel which is our main research area nearby the NIOZ institute on Texel. Our fieldwork is facilitated by the NIOZ Research Vessel Navicula and the mobile bird observatory, the Wadden Potoon 'De Richel' which makes our fieldwork efficient and flexible.

New subspecies of bar-tailed godwit officially recognized
As of today there are no longer just five subspecies of bar-tailed godwits, but six. In the latest issue of the ornithological journal Ibis, a new subspecies is described by an international team of biologists. “Limosa lapponica yamalensis has a…

Satellite-tagged red knots will cross borders this summer, while home-stuck scientists are forced to track them online to the High Arctic
Last week, 13 red knots have been equipped with light-weight satellite tags (4-5 g) in the easternmost part of the German Wadden Sea in Schleswig-Holstein. The birds have been caught by the VICI-team of Jan van Gils (NIOZ) in collaboration with Jutta…

What are the odds: same individual bird ‘Yellow-Green’ found by same researcher three times, 8,500 kilometres apart
A male knot that was fitted with colored rings in Siberia in July 2019, was resighted yesterday in the Wadden Sea, east of the island of Texel. He is one of the very first knots that arrived in the Dutch Wadden Sea this spring. Last November, this…

Migratory birds are worse off in West Africa
Migratory sandpipers breeding in Greenland who choose to spend the winter in West Africa instead of elsewhere along the East Atlantic coast have a lower chance of survival, are more likely to skip their first breeding season and arrive later at their…
