Glaucous Gull (Larus hyperboreus), 3cy, 18.01.2020, Grenå Harbour

Together with a 1cy Caspian Gull (Larus cachinnans).

Lesser Black-backed Gull (Larus fuscus graellsii), ad, 18.1.2020, Grenå Harbour

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.
