Descrição
The lake of Boren hosts a large variety of waterfowl. Dabbling ducks are often plentyful in the lake (sometimes numbering in the hundreds) during spring and some of whom stay to breed. During autumn and winter the lake is often dominated by geese (most common are Ganso-comum, Ganso do Canadá, and Ganso-campestre. But often also: Tundra Bean Goose, Ganso-de-bico-curto and Ganso-grande-de-testa-branca), and mergansers (mainly Merganso-pequeno and Merganso-grande). Among them it is not uncommon to find a few marine ducks (mainly Pato-de-cauda-afilada, Zarro-bastardo and Pato-preto). In the lake Frisada, Mergulhão-de-crista, Corvo-marinho-de-faces-brancas, Zarro-negrinha, Cisne-vulgar and many more often nest.
The reedbeds in the southern part of the lake are often used by Rouxinol-grande-dos-caniços, Abetouro-comum, Felosa-dos-juncos, and Tartaranhão-ruivo-dos-pauis. In the north Noitibó da Europa and Galinhola can often be heard during the night. There are large amounts of deciduous forest around Sjöboknäppan which attract Quebra-nozes, Papa-moscas-pequeno, Pintarroxo-carmíneo and Felosa-comum and many more.
A migration route passes through the lake during the spring migration in May with migrating tern, waders, and gulls sometimes seen in larger numbers. Among these Gaivota-pequena and Gaivina-preta are sometimes found. The lake holds often Galeirão-comum, Frango-d'água, Merganso-pequeno, Mergulhão-pequeno and Cisne-bravo during the winter. If the lake is ice-free during this period large amounts of ducks, and geese also winter on the lake. In and around the lake 204 bird species have been recorded.
