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 Eurasian Coot, Goosander, Mallard, Tufted Duck, Mute Swan, Canada Goose, European Herring Gull and Common Goldeneye can be found. Often numbering in the hundreds. Within these flocks rarer wintering birds like Great Crested Grebe, Northern Lapwing, Whooper Swan, dabbling ducks, Little Grebe , Greater White-fronted Goose, Common Starling, Common Pochard, and Great Cormorant can be spotted. The large amounts of wintering birds attract birds of prey like White-tailed Eagle, Common Buzzard, and Hen Harrier.
When the ice melts large amounts of pipits, larks, geese, Whooper Swan, and sometimes Bewick's Swan, 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 Jack Snipe, Common Redshank, Common Ringed Plover, Northern Lapwing, and Common Greenshank. The reedbeds around the lake are now filled with birds. Some rare birds who are sometimes found around the lakes are Great Bittern, Savi's Warbler, Bearded Tit and Great Reed Warbler. Some rare terns and gulls like Little Gull and Black Tern pass the lake during the spring migration.
Some rarer breeding birds at the lake are Great Reed Warbler, Great Bittern, Grey Partridge, Lesser Spotted Woodpecker, Corn Crake and Common Kingfisher. Norrbysjön is and excellent area for night active birds. Around the lake Corn Crake, Common Quail, Grasshopper Warbler, Thrush Nightingale, River Warbler, Marsh Warbler 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 Snow Bunting, Lapland Bunting and Red-throated Pipit are often found. Hundreds of European Golden Plover can often be found on the fields. Sometimes marine ducks like Common Scoter and Velvet Scoter stay at the lake.
