  • An update on the project by NIOZ and the University of Amsterdam who have fitted our juvenile and adult Lesser Black-backed Gulls with a GPS-logger.
  • A comparison using stable isotopes between the diet of our gulls at Forteiland and those at a similar colony at Texel.
  • Various other projects including research into bird flu.
  • Results of the Oystercatchers and Common Gulls that are breeding on the island.
  • Observations of other bird species and mammals.
  • An interesting insight into the beetles that are present on the island.
