Zastów Karczmiski & Wytyckie Lake, 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).
50 km's to northeast of Lublin, close to the town of Urszulin, is a large lake called "Wytyckie" (in Polish: Jezioro Wytyckie), about 1700 x 3700 meters large. It is dotted with small islands and fringed with reedbeds, and this location too holds good numbers of Larus cachinnans, about 150 breeding pairs in 2012.
In both locations, Zastów Karczmiski and the lake Wytyckie, Polish ringer and illustrator Łukasz Bednarz spend much time in the breeding season between April and July to do ringing projects and field research.

The map below illustrates the ringing activities in eastern Poland for year 2012 (courtesy Łukasz Bednarz). It is clear most time and energy was spend on ringing birds in the colony of lake Wytyckie.

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).

Location Wytyckie Lake.

In breeding season 2012, Larus cachinnans were ringed mainly at location Wytyckie Lake, near Urszulin. In total the ringing team ringed 59 adults "large white-headed gulls" (most cachinnans) and 160 pulli.
From these birds, they have received a total of 143 reports of recoveries, including 31 foreign recoveries. For most of the birds, the main migrating direction was westwards, although a few birds were seen in Sweden and Italy (and even south of Rome, which is a good 1241 km from the native colony in Wytyckie Lake.

Among the birds travelling the largest distance, were 1st winter birds flying to the south of the English Channel in NW France, which is a mere 1451 km from the ringing place. Other young birds were seen in Belgium (still a good 1325 km) and in the Netherlands (1217 km) from the ringing location.

See map below (blue pointers are birds ringed in Zastów Karczmiski, yellow pointers for birds from Lake Wytyckie):

It is always nice to get reports from distant locations, far abroad (the countries mentioned above, but also Sweden, Croatia, Hungary, the Czech Republic and Slovakia); but bulk of the ringed birds spend the winter in western Poland and in Germany. Of all the birds observed in Poland, most ring reading reports come from The Witoszówka (Lower Silesia), as well as from the surroundings of Poznań and Bydgoszcz. A few birds were seen also on the Polish coast of the Baltic Sea. Anyone looking for ringed birds especially, should check among the many gulls that feed on landfills in winter. The Uskok's Group is a group checking gulls regularly, they took control and worked mostly on the joints in Siemieniu, in Stoczek near Czemiernik in the Valley of the Tyśmienicy, as well as on the Vistula River.

In breeding season 2014, Łukasz Bednarz examined many breeding birds in the hand, on both locations. For both locations, a set of ringed birds has been added to this website.

- birds ringed in 2014 at Zastów Karczmiski.

- birds ringed in 2014 at Wytyckie Lake.`

Another location was visited, only to ring birds on one day, as it is a much smaller population:

- birds ringed in 2014 at Wincentów near Lublin.
