Heuglin's Gull L heuglini
1-3: © Visa Rauste, 14-06-02. Syktyvkar, Russia.
Compared to the previous birds, this 2cy heuglini is again slightly less advanced. It shows a moult pattern similar to many graellsii: scapulars renewed but many wing coverts, several tertials, the tail and all remiges still juvenile. The complete moult has not started yet. Plumage-wise it differs much from the average graellsii but note similarities with this Norwegian intermedius.
