Omissus

Omissus (Larus argentatus omissus) is a variant of European herring gull. It is largely similar to a common herring gull, but unlike the common species, it has yellow legs.

European herring gull of the omissus variant in Ystad 2020.

There is very little research and documentation about the omissus variant, some authors believe that it may be a species of its own.

Omissus can be confused with the Yellow-legged gull, but the omissus does not have as distinctly bright yellow legs as the yellow-legged gull.

Omissus was first described in 1928 by the Russian ornithologist Theodor Pleske
