Warden Anke Bruin-Kommerij writes today about this new nesting species for the island.
They nest in Kroon’s polders.
Great black-backed gulls started nesting regularly in the Netherlands in 1993. In 2014 there were some 60 nesting couples. They have nested on Texel, Terschelling, Ameland, Griend, and Rottumeroog islands, Zeeland province, along the IJsselmeer lake and in the Lauwersmeer national park.
