Western Lesser Black-backed Gull (Larus fuscus graellsii), ad, 23.1.2015, Aarhus Harbor

This putative Western Lesser Black-backed Gull (Larus fuscus graellsii) was seen on January 23, 2015 on Aarhus Harbour in Denmark. 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.


Another Herring Gull (Larus argentatus) with yellowish legs

This European Herring Gull (Larus argentatus) was seen on January 3, 2015 at Havmølle Å on Djursland in Denmark. Note the yellowish legs, rather distinct primary pattern with much black, incomplete band on P5 and upperparts a little darken than on nearby argentatus (see video for color on upperparts).

Herring Gull (Larus argentatus) with much white in primaries

This Herring Gull was seen in Hanstholm Harbour on 30 December 2013. It has a primary pattern which reminds of what is seen in some birds labelled as hybrid hyperboreus x argentatus (Viking Gull), but as it lacks a clear influence from Glaucous Gull other than in the outer primaries, it is considered to be European Herring Gulls with reduced or aberrant pigmentation.

Note the distinct thayeri pattern on P9 on the adult-type Herring Gull in the front
