Description
Ölstadsjön is a nature reserve and one of the best sites for dabbling ducks in the municipality of Finspång. Although not nearly as good as the sites on the Östgöta plain Rață cârâitoare, Rață mică, Rață mare, Rață fluierătoare and Rață lingurar have all been sighted. The lake has a quite restricted area of open water so the amounts are often lacking. Other common ducks of the diving kind have also been observed. The lake was once known for its population of breeding Corcodel de iarnă, and even Corcodel cu gât negru although they are both now gone. Around the lake relatively large amounts of geese often rest all seasons except winter. Most common are Gâscă călugăriță, Gâscă canadiană and Gâscă de vară, although Gârliță mare also have been sighted. Egretă mare has been sighted and Stârc cenușiu is common.
The area around Ölstadsjön is rich in birds of prey with wetland birds like Erete de stuf, Șorecar comun, Șorecar încălțat, Codalb, and Erete vânăt often beein observed along with visitors from the forest like Uliu păsărar, Uliu porumbar and Uligan pescar.
On the field Ciocârlie, Fluierar de zăvoi, Sticlete, Graur Nagâț, Fâsă de luncă and Cânepar are often seen. Even Prepeliță has been heard. In the lake some gulls and tern are often sighted.
In the reeds Cârstel de baltă, Presură de stuf, Buhai de baltă (not often), Lăcar mic, and Lăcar de stuf are observed.
