Description
Obszar Dawnej Kopalni Siarki Jeziórko is a vast open area with 19 ponds, several hundred hectares of meadows, reed beds and wetlands in post-mining sinkholes. Over 200 species of birds (115 breeding birds) have been observed here. It is an excellent place to observe the breeding gulls such as Riječni Galeb, Galeb Klaukavac, Crnoglavi Galeb and waders like Crvenonoga Prutka, Kulik Sljepčić and Veliki Pozviždač. Also other water birds and herons can be seen here like Siva Štijoka, Riđa Štijoka, Kokošica, Liska, Kosac, Čapljica Voljak and Bukavac.
During spring migration, you can observe flocks of geese (up to several hundred individuals) Siva Guska, Lisasta Guska, Tundra guska, Mala guska and Sjevernomorska guska, ducks (up to several thousand) Patka Njorka, Patka Lastarka, Patka Gogoljica, Krunata Patka and Glavata Patka, etc.
In late autumn, regular groups of Bijeli ronac (the largest in the region), as well as Crnogrli Plijenor, Crvenogrli Plijenor and Mali ronac can be seen. In winter you can regularly observe, among others Eja Strnjarica, Škanjac gaćaš and Štekavac. Among the owls observed in this area, Sova močvarica and breeding and Mala Ušara should be mentioned. It's worth having a telescope with you, but with the binoculars only you can easily see most species.

Access
The easiest way to get to the Jeziórka area is from the Grębów - Tarnobrzeg road. The oldest post-mining ponds are already visible from the road, an asphalt road leads deep into the area (further on, shallow and gravel). You can also enter or walk from the side of Wydrza on a gravel road (turn after the Primary School in Wydrza).
A very convenient means of transportation is by bike, but you might as well get there by car or hitchhike and just walk around the whole area.
