First record of Kumlien's Gull in Germany

The German Rarity Committee Deutsche Seltenheitenkommission (DSK) has accepted one record of Kumlien’s Gull from the major influx in Europe during the winter 2011-2012.

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.

Iceland Gull (Larus glaucoides), 3cy, 08.01.2012, Blåvandshuk, Blåvand

Date: 2012-01-08
Site: Blåvandhuk, Denmark
Observer: *Henrik Brandt, *Per Poulsen

It is considered to be an Iceland Gull (Larus glaucoides) though this is not to say it is not a Kumlien's Gull. It has without doubt some faint pigmentation along the tip of the outer primaries. However, note that it is not abnormal for 2nd- and, especially, 3rd-cycle glaucoides to show a brown wash on the outer primaries. The plumage of these immature gulls often looks quite retarded, with still lots of brown in the wing. Note that the brown wash on outer primaries of such birds simply matches the brown wash on outer secondaries, as is often the case in other 3rd-cycle gulls (e.g. Herring Gull). It is just a trait of immature plumage.

Kumlien's Gull (Larus [glaucoides] kumlieni), 4cy, 09.01-05.03.2012, Hanstholm Harbour, Hanstholm

Case: 2012-248
Date: 2012-01-09 -(03-05)
Site: Hanstholm Harbour, Denmark
Observer: Troells Melgaard, Klaus Malling Olsen, Henrik Haaning Nielsen m.fl.

This individual has been identified as Kumlien’s Gulls based on its primary pattern. Note that there is subtle dark shading on the outer webs of the outer four primaries with the colour being darker on the outer than on the inner web. Moreover, the dark shading on P7-P9 reaches the primary tips where the dark colour creates a back-curving hook onto the inner webs which is considered to be a significant kumlieni character. As is often the case with immature Kumlien’s Gulls, the dark colour is often darkest at the very tip of the primaries and also half way out on the outer web. Another very important character is the faint 'ghost mirror' on P10 combined with a dark sub-terminal pattern.

Note that the dark shading on the outer primaries is darker than the shading on the inner primaries and the primary coverts. Additionally, the outer primaries are also darker than the secondaries. The combination of the pseudo-mirror on P10 and dark subterminal spots, dark outer webs on the outer primaries and dark pattern forming a hook onto the inner webs should exclude the brown-winged glaucoides known from West Greenland and Iceland
