Beskrivelse: In many US-fiels guides this is a Whimbrel - and like that also (partly)on 'netfugl' (since the ssp. rufiventris is a possible 'hit' when one look up 'Whimbrel').
Also N. hudsonicus (American Whimbrel) is a possibility... also to find on 'netfugl'.
Avibase recognizes the split.
I don't know what to believe - anyway: sub-species or full species? - this is the bird I saw :-)

Hi Richard,
Could you give some input to why this is a hybrid? If I saw this bird in Denmark I would mostlikely just have called it a Glaucous Gull.
Best regards
Jens
Yeah structurally the head is all wrong for a Glauc - it's one dopey looking beast with that large eye, lacking any snouty look while the dark tip bleeds into the gape on close inspection as well as the thick set structure more akin to Glauc-winged. Additionally, even for a Glauc, it's very short-winged...
Cheers
Rich
I don´t think the structure is "totally wrong" for a Glaucous, regarding that we have a West Coast bird here. The wing is short, but similar short wings can be seen in many males, which however normally will appear "bruter2 than this bird. But few characters are wrong for Glaucous:
1: the bill is too dark at basal parts, and the black tip has a diffuse division from the paler basal parts, whereas a 100% Glaucous should have pink bill with sharper divided black tip.
2: the presence of some more uniform grey feathers in breast-sides, flanks and hindneck is a character from Glaucous-winged.
ID of the gull as a hybrid Glaucous x Glaucous-winged Gull is thus advocated.
