I am going to use the widely-accepted (in Europe) English
name for this form: Caspian
Gull Larus cachinnans; this form is also
referred to as Steppe Gull, and L. argentatus cachinnans,
and L. michahellis cachinnans. I include in this form
the taxon ponticus - with the English name Western Caspian
Gull, and nominate cachinnans - with the English name
Eastern Caspian Gull. I am placing images of the form barabensis
in a separate location. Note that all identifications of birds
in Bahrain are tentative,
especially my assignments to race (ponticus or cachinnans)
- please interpret each use of a racial name (xxx) as
meaning "appears to be closest to xxx based upon
population averages":
