The accepted bird was a 3cy individual seen 15.3-5.4.2012 in Salzgitter Heerte in Niedersachsen. Martin Gottschling has kindly allowed me to include his photos in this post.

Kumlien’s Gull in Norway during the record influx in 2012

The Norwegian Rarities Committee (NSKF) has recently accepted seven records of Kumlien’s Gull from the major influx during the winter 2011-2012. However, note that not all claims have yet been submitted and the actual number of Kumlien's Gull in Norway during the influx may thus be higher.

Herring Gull (Larus argentatus) with reduced pigmentation seen in Grenaa Harbour

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.

Caspian Gull (Larus cachinnans), 1cy, 14.9.2014, Grenaa Harbour














As highlighted by Lou Bertalan please note that the P5 in right wing is pale and looks like a 2nd generation feather.

Note that the pale P5 in right looks like a 2nd generation feather. S1 in left wing is pale greyish in a similar way

Caspian Gull (Larus cachinnans), 4cy, 14.9.2014, Grenaa Harbour

This could be a pure cachinnans and even though one may argue that most of the features seen in this bird also fit argentatus, there are firm clues that at least one of the parents must have been a cachinnans. Even though the upperparts are rather pale; iris rather pale; head relatively striated; and the black band on P5 rather narrow, it would not surprise me if it still fits within the phenotypic variation found in true cachinnans. However, a hybrid or backcross is not easy to rule out.

The winter streaks in head are needle-thin and very distinctive without the typical coarse spotted argentatus appearance; cachinnans can have such streaks in autumn as also seen on Netfugl.

Characters in favor of cachinnans are e.g. the relative and thin long legs compared to the adjacent Herring Gulls, a bill which is relative slim without pronounced gonys angle, a dark red orbital ring, reminiscence of a cachinnans neck boa with dark spots on lower neck, and upperparts which are marginally darker than on nearby argentatus.
