It's Impossible

What's impossible? Gull ID, that's what! Well, maybe not impossible, but always a challenge.

Here's a few pics from Stubber's Green today, which may or may not illustrate this point.



Yellow-legged gull - note the yellow legs



Yellow-legged gull - note the absence of any legs!



Common gull - not actually all that common!



Great black-backed gull - okay, that one's fairly easy



Caspian gull? No. Had us excited for a bit though!

Here's another picture, taken at the same site last year, of a probable Caspian gull.



Was it? Who knows?

I love gulls, me!
