Sanderling Project

Sanderlings (Calidris alba) are long-distance migrating shorebirds that occur in intertidal areas, and particularly on sandy beaches, worldwide. They are well known as the clock-work-toy shorebird that runs in and out of the surf, but there are still many unknowns about the life of this enigmatic wader. We intend to answer those questions about the life of Sanderlings, and anyone can help us with this.


The Sanderling Project of the International Wader Study Group aims to learn more about migration routes, phenology and survival and reproduction of Sanderlings in Europe, Africa and Asia. The project aims to:

  • create an international network of Sanderling enthusiasts
  • increase the number of colour-ring resightings in Europe, Africa and West Asia
  • organise, stimulate and aid in setting up standardised catches of Sanderlings in Europe, Africa and West Asia
  • organise and stimulate (age) counts of Sanderlings

The Sanderling Project team consists of:

  • Jeroen Reneerkens (Project leader) in close collaboration with a.o.:
  • Niels Martin Schmidt, Olivier Gilg, Johannes Lang, Jannik Hansen and others (Greenland)
  • Gunnar Thor Hallgrimsson (Iceland)
  • José Alves (Portugal)
  • Farlington Ringing Group (United Kingdom and Portugal)
  • Shorebird Group NIOZ (Wadden Sea and Mauritania)
  • Prof. Yaa Ntiamoa-Baidu / Ghana Ringing Scheme (Ghana)
  • Mark Boorman (Namibia)
  • Hilger Lemke (ageing census)
  • Colin Corse (Scotland)

and many enthusiastic sanderling observers along the East Atlantic flyway!   More content coming soon, in three languages: flag-british40flag-french40 flag-dutch40
