Herring Gull (Larus argentatus) with reduced pigmentation seen in Feldballe

Some of these pale type Herring Gulls can recall birds labelled as hybrid hyperboreus x argentatus (Viking Gull), but as this individual lacks a clear influence from Glaucous Gull when it comes to the pattern on each feather, is is considered to be European Herring Gulls with reduced or aberrant pigmentation.

It was seen on April 6, 2014.
