Your posting made it on to the IBN alright.  Only seeing the shots this 
morning and they are brilliant - well done!

It does appear to me rather too Herring Gull like in overall appearance, not 
the compact, bulky, short winged look with that classic beady eye positioned 
high and far back in the head of classic GWG.  Other than the structural 
impressions I have no real comments.  I have no first hand experience of 
those messy West Coast integrades and I find discussions re same on ID 
Frontiers hard to read.  Have you guys had any opinions from the USA?

There is something vaguely familiar about the bird - it reminds me of a 
hybrid that was at Nimmo's some years ago.  Looking at shots of supposed 
integrade Glaucous-winged X Herring on the net the primaries and tertials 
often appear darker in those birds so  I wonder could it just be a well 
marked Glaucous X Herring or a Glaucous X Great Black-backed hybrid?

Nice find Derek!

Hi Edward,

Expert opinions received so far are on the side of it being a hybrid, 
possibly Glaucous-winged x Herring Gull.

Nobody in Sligo, including the finder, Derek Charles, put the bird out as 
anything other than a possible Glaucous-winged Gull.

The note on summarises current opinion fairly well "1st 
Winter type bird showing characteristics of a Glaucous-winged Gull. 
Drumcliff Bay. Hybrid not ruled out."

I posted a link to some images of the bird last night on the IBN-L, which 
doesn't seem to have gone through to the list.

Trying again here - images are posted at

It is certainly a very striking looking bird, quite unlike any other gull we 
have seen in Sligo.  The spectacular stranding of tonnes of starfish at 
Lissadell has attracted about 1,000 gulls showing up in a concentrated area, 
which yesterday included 1 Kumliens Gull, a first winter Ring-billed Gull, 
two Iceland Gulls and this bird.



PS  Just spotted that I accidentally sent last night's email from my new 
email address which is not registered for IBN-L mail - my apologies
