Adult Steppe Gull (Larus (c.?) barabensis)
(upper bird). This individual has a somewhat armenicus-like
primary pattern, in that P7 looks similar to P8 with regard to

most armenicus, yet the outer primary coverts have prominent
blackish lines that are typical of darker barabensis and
not typical for armenicus. The lower bird is not a full
adult; I would tentatively suggest cachinnans, based on
the paler mantle and prominent gray inner-web tongues on P7 &
P6 which are paler and expand slightly at their distal tip:
