Get back to the 'Common Gull' which doesn´t at all look like a Common Gull.

Well Lou since no one else seems to go for it - i might as well have a try. I´m going fast -not much thinking ;)

1. cachinnans
2. argentatus
3. argentatus
4. cachinnans

JanJ
 
2:2 (2 out of 4 correct) ;)

ok. 1st one surely is a cachinnans with that nice mirror.
and i'm impressed about your argentatus guess, it was correct (but which one of the two o:D )
and in the 1cy one, you saw the greater covert pattern and said cachi...?

The so called 'omissus' for the argentatus.

Yes I said cachinnans because of the greater covert pattern - but also seen on several other big Larus - such as michahellis - argentatus - smithsonianus and so on. The fashion of the inner primaries also reminds of cachinnans.

So what about nr 2?

JanJ
 
but as you know the fashion of the inner primaries can be very similar in cachi and micha. sorry i can show you the tail tomorrow only, original is on my own pc.
- and the famous omissus :t: is the only one from a website, and i'm sure you have seen the pic once in your life ;)... but of course structure of this bird is quite clear. tomorrow also the other whole pics.
-2nd is not argentatus (and mantle colour is appearing too dark) 3:)
