Middle Vistule river is a location where several taxa breed: see composition. Since this is a mixed breeding population where hybridisation is not uncommon, the ringing centre in Poland decided to label birds "Larus argentatus sensu lato". Still bulk of the breeding birds in Middle Vistula region show features of cachinnans.
Zastów Karczmiski, eastern Poland. With a population of over 350.000 people, Lublin is one of the larger cities in east Poland close to both the Ukrain and the Belarus border. If you travel only 45 km to the west, you'll find yourself in the Vistula river valley (Polish: Wisła river). This is one of Poland's larger colonies of Larus cachinnans, with about 600 breeding pairs in 2012, situated close to the village Zastów Karczmiski (click link for more info). Zastów Karczmiski - islands in River Wisła, stronghold for Caspian Gulls. In 2004 240 breeding pairs (95% cachinnans, <5% argentatus). (Ornis Fennica 2011 88, 80-89) and in 2012 592 pairs (90% cachinnans, <10% hybrid / argentatus). (pers comm. Łukasz Bednarz). Picture: Paweł Jaszczuk.

The default birds breeding at Zastów Karczmiski are cachinnans, but some breeding birds belong to either michahellis or argentatus (or hybrid offspring of these two). Mixed breeding has been recorded and documented in much detail for the Vistula river valley, and this may be the origin for argentatus (and michahellis) found in Zastów Karczmiski as well. Below we show a thumbnail selection of some 10's of birds ringed at Zastów Karczmiski. |
