Beschreibung
During winter most of the Norrbysjön lake is covered in ice, but where Motala ström meets Norrbysjön the water is ususally open year round. During this period large flocks of Bläßhuhn, Gänsesäger, Stockente, Reiherente, Höckerschwan, Kanadagans, Silbermöwe and Schellente can be found. Often numbering in the hundreds. Within these flocks rarer wintering birds like Haubentaucher, Kiebitz, Singschwan, dabbling ducks, Zwergtaucher , Bläßgans, Star, Tafelente, and Kormoran can be spotted. The large amounts of wintering birds attract birds of prey like Seeadler, Mäusebussard, and Kornweihe.
When the ice melts large amounts of pipits, larks, geese, Singschwan, and sometimes Zwergschwan, use the fields around the lake as feeding grounds. The lake is usually filled with many dabbling ducks, gulls and terns. Husbyängarna are often flodded, and usually hold wading birds like Zwergschnepfe, Rotschenkel, Sandregenpfeifer, Kiebitz, and Grünschenkel. The reedbeds around the lake are now filled with birds. Some rare birds who are sometimes found around the lakes are Rohrdommel, Rohrschwirl, Bartmeise and Drosselrohrsänger. Some rare terns and gulls like Zwergmöwe and Trauerseeschwalbe pass the lake during the spring migration.
Some rarer breeding birds at the lake are Drosselrohrsänger, Rohrdommel, Rebhuhn, Kleinspecht, Wachtelkönig and Eisvogel. Norrbysjön is and excellent area for night active birds. Around the lake Wachtelkönig, Wachtel, Feldschwirl, Sprosser, Schlagschwirl, Sumpfrohrsänger can often be heard at the lake.
During autumn large amounts of geese start to visit the lake again. Many more passerine birds can be found on the fields. Among these Schneeammer, Spornammer and Rotkehlpieper are often found. Hundreds of Goldregenpfeifer can often be found on the fields. Sometimes marine ducks like Trauerente and Samtente stay at the lake.
