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 Лысуха, Большой крохаль, Кряква, Хохлатая чернеть, Лебедь-шипун, Канадская казарка, Серебристая чайка and Гоголь can be found. Often numbering in the hundreds. Within these flocks rarer wintering birds like Чомга, Чибис, Лебедь-кликун, dabbling ducks, Малая поганка , Белолобый гусь, Обыкновенный скворец, Красноголовый нырок, and Большой баклан can be spotted. The large amounts of wintering birds attract birds of prey like Орлан-белохвост, Канюк, and Полевой лунь.
When the ice melts large amounts of pipits, larks, geese, Лебедь-кликун, and sometimes Американский лебедь, 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 Гаршнеп, Травник, Галстучник, Чибис, and Большой улит. The reedbeds around the lake are now filled with birds. Some rare birds who are sometimes found around the lakes are Большая выпь, Соловьиный сверчок, Усатая синица and Дроздовидная камышевка. Some rare terns and gulls like Малая чайка and Чёрная крачка pass the lake during the spring migration.
Some rarer breeding birds at the lake are Дроздовидная камышевка, Большая выпь, Серая куропатка, Малый пёстрый дятел, Коростель and Обыкновенный зимородок. Norrbysjön is and excellent area for night active birds.

During autumn large amounts of geese start to visit the lake again. Many more passerine birds can be found on the fields.
