2cy cachinnans: June

Trapping and ringing of Larus cachinnans in breeding season 2014. More info about this project.

Locations:
- Largest Polish colony at the banks of the Middle Vistula river; birds ringed at Zastów Karczmiski (click link).
- Few birds ringed at Wincentów near Lublin (click link).
- Birds ringed Wytyckie Lake near Urszulin, eastern Poland presented below, on this page.

The default birds breeding at Wytyckie Lake are cachinnans, but some breeding birds belong to either michahellis or argentatus (or hybrid offsprings 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 Wytyckie as well. There is at least some exchange between Wytyckie and Zastów, as illustrated by 1P34.

Few images to illustrate Wytyckie Lake and the nesting situation on the island in the lake: small wooded islands where the chicks can hide in the vegetation. Pictures: Łukasz Bednarz ringing team. (click images to view larger sizes)
