At Waardenburg Ecology I lead a team of bird ecologist on various projects ranging from multi-year monitoring programs to smaller consultancy work. My own main research focus is on the foraging ecology of Sandwich Terns in the Netherlands, including tracking with GPS loggers and colour rings. Other projects focus on the effects of offshore windfarms on birds. We conduct and analyse many marine wildlife cencuses, use radar to study bird flight, and use geolocators and GPS loggers to track birds.
