Gulls, Tbilisi, Georgia (1 Viewer)

[Val35]

Saw plenty of gulls in Georgia and a few are confusing to me. I know the main species in Tbilisi are Yellow-Legged, Caspian and Armenian.
These with dark irises and small rounded heads look like Armenian to me but the bill pattern doesn't quite fit (or is there a lot variation ? Maybe also depends on the age of the birds ?). Thanks for your input, all pics taken in Tbilisi on the 16th of September. Each pic is a different bird.

All Armenian. The black band on the bill is mainly present outside of breeding season and is starting to appear on some of these.

Thank you very much ! Interesting, for some reason I thought it was actually appearing during the breeding season and wondered why it was kind of faint on those birds.
