By October, most Lesser Black-backed Gulls have left the colonies and surrounding feeding grounds near the Maasvlakte (the Netherlands) and migrate south towards France, Portugal and Morocco. Many first winter birds that are still present in the Netherlands have moved in from northern breeding grounds in Southern Scandinavia: south tip of Norway (Vest-Agder, Kristiansand), SW Sweden (Bohuslän to Malmö), northern Germany (Helgoland) and Denmark.

At least several of these intermedius LBBG may stay in the Netherlands in winter, as proved a Swedish ringed individual, seen at December 21 2000 at Westkapelle. During late fall and early winter we did some surveys in the south of the Netherlands at the Maasvlakte (port of Rotterdam) and along the coast at Westkapelle, 65 km south of the Maasvlakte (see map). More details can be found at the distribution Section. 

Origin of 1cy LBBG in October

The juvenile - first winter Lesser Black-backed Gulls present in October in the Netherlands originate from all directions: Belgium and Britain (race graellsii), local Dutch LBBG (known as Dutch intergrades) and Scandinavian LBBG of race intermedius.
