Description
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 Foulque macroule, Harle bièvre, Canard colvert, Fuligule morillon, Cygne tuberculé, Bernache du Canada, Goéland argenté and Garrot à oeil d'or can be found. Often numbering in the hundreds. Within these flocks rarer wintering birds like Grèbe huppé, Vanneau huppé, Cygne chanteur, dabbling ducks, Grèbe castagneux , Oie rieuse, Étourneau sansonnet, Fuligule milouin, and Grand Cormoran can be spotted. The large amounts of wintering birds attract birds of prey like Pygargue à queue blanche, Buse variable, and Busard Saint-Martin.
When the ice melts large amounts of pipits, larks, geese, Cygne chanteur, and sometimes Cygne de Bewick, 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 Bécassine sourde, Chevalier gambette, Grand Gravelot, Vanneau huppé, and Chevalier aboyeur. The reedbeds around the lake are now filled with birds. Some rare birds who are sometimes found around the lakes are Butor étoilé, Locustelle luscinioïde, Panure à moustaches and Rousserolle turdoïde. Some rare terns and gulls like Mouette pygmée and Guifette noire pass the lake during the spring migration.
Some rarer breeding birds at the lake are Rousserolle turdoïde, Butor étoilé, Perdrix grise, Pic épeichette, Râle des genêts and Martin-pêcheur d'Europe. Norrbysjön is and excellent area for night active birds. Around the lake Râle des genêts, Caille des blés, Locustelle tachetée, Rossignol progné, Locustelle fluviatile, Rousserolle verderolle 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 Bruant des neiges, Bruant lapon and Pipit à gorge rousse are often found. Hundreds of Pluvier doré can often be found on the fields. Sometimes marine ducks like Macreuse noire and Macreuse brune stay at the lake.
