Re: Herring Gull or???

I did not myself see the gull and the observer only managed this single shot, so we have no view of tail or opened wing. It might not be possible to judge from this single photo, but I have trouble seeing any white p10 mirror, I find the upperpart pattern rather unusual for a second winter cachinnan...

Herring Gull or???

This second winter gull from Denmark has been debated: http://langelandsfugle.wordpress.com/2011/02/01/ny-kaspisk-mage-i-spodsbjerg-havn/#comment-31 Some states that it is a Caspian Gull, but to me it is most likely a Herring Gull (rather matching this one: http://www.talk.gull-research.org/viewtopi...

Re: Larus canus?

Also to me it is a Common Gull. Just for comparison here is a Danish bird with heavily patterned underparts: http://gulldk.blogspot.com/2008/01/stormmge-larus-canus-2k-1122005-rhus.html and some 1st winter plumage variation in Common Gull seen en Norway 2010: http://gulldk.blogspot.com/2010/09/commo...

Re: leucistic Herring Gull?

Hi Peter,

Thanks for your comment.

What also says that it is a Herring Gull is the reduced white tertial and scapular crescent.

New photos have been added including the standing bird and stretched wing: http://gulldk.blogspot.com/2010/12/herr ... _7918.html

leucistic Herring Gull?

To me this is a leucistic Herring Gull, but people start to speculate… http://gulldk.blogspot.com/2010/12/herring-gull-larus-argentatus-with_13.html As fare I can tell there are two coverts on the left side which looks wheat, but in fact show a degree of normal pigmentation and thus appear darker th...

Re: Can this be argenteus?

Here is another Herring Gull with long, pale tongue on the underside of P10. Please note the yellowish leg colour indicating an eastern or north-eastern origin. http://3.bp.blogspot.com/_wpfoS655UiU/R4p5faV1L6I/AAAAAAAAAXU/-BA3W6F9r2s/s1600-h/KEO01625E995_29.11.2007.JPG and http://1.bp.blogspot.com/...

Re: Caspian? or hybrid in Denmark

Hi Jan, Great, that you would share a comment. I fully accept that due to the change in appearance between the different photos nobody feels comfortable with a final ID. Nevertheless it’s an interesting gull which forced me to follow it for a long time in order to take documentation for all the diff...
