Descrição
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 Galeirão-comum, Merganso-grande, Pato-real, Zarro-negrinha, Cisne-vulgar, Ganso do Canadá, Gaivota-argêntea and Pato-olho-d'ouro can be found. Often numbering in the hundreds. Within these flocks rarer wintering birds like Mergulhão-de-crista, Abibe-comum, Cisne-bravo, dabbling ducks, Mergulhão-pequeno , Ganso-grande-de-testa-branca, Estorninho-malhado, Zarro-comum, and Corvo-marinho-de-faces-brancas can be spotted. The large amounts of wintering birds attract birds of prey like Águia-rabalva, Águia-d'asa-redonda, and Tartaranhão-azulado.
When the ice melts large amounts of pipits, larks, geese, Cisne-bravo, and sometimes Cisne-pequeno, 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 Narceja-galega, Perna-vermelha-comum, Borrelho-grande-de-coleira, Abibe-comum, and Perna-verde-comum. The reedbeds around the lake are now filled with birds. Some rare birds who are sometimes found around the lakes are Abetouro-comum, Felosa-unicolor, Chapim-de-bigode and Rouxinol-grande-dos-caniços. Some rare terns and gulls like Gaivota-pequena and Gaivina-preta pass the lake during the spring migration.
Some rarer breeding birds at the lake are Rouxinol-grande-dos-caniços, Abetouro-comum, Perdiz-cinzenta, Pica-pau-malhado-pequeno, Codornizão and Guarda-rios-comum. Norrbysjön is and excellent area for night active birds. Around the lake Codornizão, Codorniz, Felosa-malhada, Rouxinol-russo, Felosa-fluvial, Felosa-palustre 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 Escrevedeira-das-neves, Escrevedeira da Lapónia and Petinha-de-garganta-ruiva are often found. Hundreds of Tarambola-dourada can often be found on the fields. Sometimes marine ducks like Pato-preto and Pato-fusco stay at the lake.
