IJmuiden Gull Research Team season 2022 review

Our review of the 2022 season describing the results of our research into Lesser Black-backed Gulls, Herring Gulls, Common Gulls, and Oystercatchers at IJmuiden Forteiland in the Netherlands is now available.


  • The season was very successful in terms of the number of birds that fledged.
  • A small decline in the number of breeding birds was recorded compared to last year.
  • While avian flu had a huge impact in bird colonies across the country, our colony was fortunately spared. Only a few individuals were affected.
  • The Lesser Black-backed Gulls that are fitted with GPS loggers once more showed very interesting data, with one adult wintering as far south as Dakla in the Western Sahara.
  • We observed mixed Herring Gull and Lesser Black-backed Gull pairs and a Lesser Black-backed Gull family with 4 chicks.

The report is available as a PDF and can be downloaded via the following links:
