Opis
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 łyska, nurogęś, krzyżówka, czernica, łabędź niemy, bernikla kanadyjska, mewa srebrzysta and gągoł can be found. Often numbering in the hundreds. Within these flocks rarer wintering birds like perkoz dwuczuby, czajka, łabędź krzykliwy, dabbling ducks, perkozek , gęś białoczelna, szpak, głowienka, and kormoran can be spotted. The large amounts of wintering birds attract birds of prey like bielik, myszołów, and błotniak zbożowy.
When the ice melts large amounts of pipits, larks, geese, łabędź krzykliwy, and sometimes łabędź czarnodzioby, 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 bekasik, krwawodziób, sieweczka obrożna, czajka, and kwokacz. The reedbeds around the lake are now filled with birds. Some rare birds who are sometimes found around the lakes are bąk, brzęczka, wąsatka and trzciniak. Some rare terns and gulls like mewa mała and rybitwa czarna pass the lake during the spring migration.
Some rarer breeding birds at the lake are trzciniak, bąk, kuropatwa, dzięciołek, derkacz and zimorodek. Norrbysjön is and excellent area for night active birds. Around the lake derkacz, przepiórka, świerszczak, słowik szary, strumieniówka, łozówka 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 śnieguła, poświerka and świergotek rdzawogardły are often found. Hundreds of siewka złota can often be found on the fields. Sometimes marine ducks like markaczka and uhla stay at the lake.
