Gull Identifications - Chew Valley Lake, England 26.08.18

I struggle with gulls - particularly judging the alleged differences in bill size & structure and the variability of tertial patterns. So help with the attached gratefully received.

I have identified the first as a Great Black-backed Gull, the second and third as Herring Gulls and the fourth and fifth as Lesser Black-backed Gulls.

Many thanks

Paul

Agree on ##1-4. Think #5 might be another Herring, as it has pale notches on the tertials.

But I'm crap at immature large gulls as well, so don't rely on my guesses

Three has been correctly identified as a Yellow-legged Gull. (I really am terrible on juvenile gulls.)

All the best

Of #3 - if the bird was at Mornington Crescent, then it was a YLG

Just the one pic retained. I tend to be fairly brutal in only keeping one of very similar shots or deleting inferior ones and I only took a profile picture.

All the best
