Wader distribution

Wader map musselbed North Sea


We investigate the spatio-temporal use of the Balgzand area, a shallow area in the Dutch Western Wadden Sea, by Oystercatchers (Haematopus ostralegus) to gain more insight into the use of the intertidal area by the Oystercatcher in relation to fine-scale structures in sediment, immersion time and food availability.

We use GPS tracking to monitor the whereabouts of birds throughout the season in combination with a stand-alone camera which collects continuous observations of all foragers near a local mussel and cockle bed. By using the GPS and camera observations in conjunction, a rich data set is constructed which is being used to develop and test site-specific foraging models.

This project is a collaboration between the CGE Group, the IMARES Institute and the Dutch Centre for Field Ornithology (SOVON) and is financed by the Netherlands Science Foundation (NWO).
