Over 200 species of birds (115 breeding birds) have been observed here.

In late autumn, regular groups of бел нуркач (the largest in the region), as well as белец, мал морски нуркач and среден северен нуркач can be seen. In winter you can regularly observe, among others Полска еја, гаќест глувчар and белоопашест орел. Among the owls observed in this area, блатен був and breeding and ушест був 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.
