Lesser Black-backed Gull (Larus fuscus graellsii), ad, 27.8.2010, Aarhus Harbor

Putative Western Lesser Black-backed Gull (Larus fuscus graellsii). This individual is the second graellsii in Aarhus Harbor today and also the second individual this summer. The first is documented here.

Judged only on upper part colors we cannot safely dismiss an intergrade between intermedius and graellsii, but it is much paler than a classical Danish breeding intermedius.
