This bird seen in W. Yorkshire this morning. Could it be fuscus or would it be intermedius?

cheers,

Dave.

Looks more like intermedius on structure. I find fuscus even more attenuated at the rear and ( allowing for wear and fading ) I wouldn't expect there to be as great a contrast between the upperparts and wingtips. Having said that there is a fair amount of overlap so..................

Just for interest, another couple of pics added to try and show the birds size which was quite slighter than the accompanying LBBG.

if you can find a picture of the Lackford Lake possible fuscus from earlier in the year and compare the size difference you will notice a great deal of size between it and lbb gull. almost black headed gull in size.

There's great difference in size between male and female, this with individual variation makes size quite useless as a id feature.

In Finland this bird wouldn't catch my eye, but when identifying LBBGs location is always the most important criteria (same with Herrings) :)
