Descrição
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 Guincho-comum, Gaivota-de-patas-amarelas, Gaivota-de-cabeça-preta and waders like Perna-vermelha-comum, Borrelho-pequeno-de-coleira and Maçarico-real. Also other water birds and herons can be seen here like Franga-d'água-bastarda, Franga-d'água-grande, Frango-d'água, Galeirão-comum, Codornizão, Garça-pequena and Abetouro-comum.
During spring migration, you can observe flocks of geese (up to several hundred individuals) Ganso-comum, Ganso-grande-de-testa-branca, Tundra Bean Goose, Ganso-pequeno-de-testa-branca and Ganso-de-faces-brancas, ducks (up to several thousand) Zarro-castanho, Arrabio, Pato-de-bico-vermelho, Zarro-negrinha and Zarro-comum, etc.
In late autumn, regular groups of Merganso-pequeno (the largest in the region), as well as Mobêlha-árctica, Mobêlha-pequena and Merganso-de-poupa can be seen. In winter you can regularly observe, among others Tartaranhão-azulado, Búteo-calçado and Águia-rabalva. Among the owls observed in this area, Coruja-do-nabal and breeding and Bufo-pequeno should be mentioned. It's worth having a telescope with you, but with the binoculars only you can easily see most species.

Acesso
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.
