Lesser Black-backed Gull (Larus fuscus graellsii), ad, 17.3.2005, Egå, Aarhus

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, but it is paler than a classical Danish breeding intermedius.
