Heuglin's Gull L heuglini

Heuglin's Gull - Larus heuglini

1-4: © Visa Rauste, 14-06-02. Syktyvkar, Russia.

A mix up of advanced 2cy fuscus with Heuglin's Gull L heuglini is rather unlikely, as only a few 2cy heuglini return to Europe with 8+ renewed primaries. This is an example of such an advanced 2cy heuglini. Note the bluish-grey adult-like feathers, much paler than in 2cy fuscus.
