Wintering oystercatchers (Haematopus ostralegus) encounter many different pressures in the Wadden Sea area. Both foraging and resting birds might be disturbed by birds of prey, walkers, cyclists, cars, boats and airplanes. On the Vliehors, oystercatchers were equipped with GPS trackers to estimate the effect of such disturbances on the behaviour and time budget. It turns out that many of these birds regularly rest and feed near Texel. Observations at oystercatcher ‘hotspots’ are needed to link the GPS data to the actual disturbances in the field. During this thesis/internship, several weeks will be spent on Texel to observe oystercatchers at high tide roosts and foraging areas. During these observations disturbance sources and their effects on oystercatchers are precisely recorded. Thereafter, those field observations will be linked to GPS data from the GPS trackers mounted on oystercatchers. More information about the project on CHIRP-website.
