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 Чирок-трескунок, Чирок-свистунок, Кряква, Свиязь and Широконоска 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 Красношейная поганка, and even Черношейная поганка although they are both now gone. Around the lake relatively large amounts of geese often rest all seasons except winter. Most common are Белощекая казарка, Канадская казарка and Серый гусь, although Белолобый гусь also have been sighted. Большая белая цапля has been sighted and Серая цапля is common.
The area around Ölstadsjön is rich in birds of prey with wetland birds like Болотный лунь, Канюк, Зимняк, Орлан-белохвост, and Полевой лунь often beein observed along with visitors from the forest like Перепелятник, Тетеревятник and Скопа.
On the field Полевой жаворонок, Черныш, Черноголовый щегол, Обыкновенный скворец Чибис, Луговой конёк and Коноплянка are often seen. Even Перепел has been heard. In the lake some gulls and tern are often sighted.
In the reeds Водяной пастушок, Тростниковая овсянка, Большая выпь (not often), Камышевка-барсучок, and Тростниковая камышевка are observed.
