Lesser Black-backed Gull (Larus fuscus graellsii), 2cy, 18.10.2010, Børsmose Strand

Putative Western Lesser Black-backed Gull (Larus fuscus graellsii). Judged only on upper part colors we cannot safely dismiss an intergrade between intermedius and graellsii (known as Dutch Intergrade), but it is much paler than a classical Danish breeding intermedius.
