Description
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 Siva Guska, Kanadska guska, and Guska Glogovnjača. But often also: Tundra guska, Crvenonoga guska and Lisasta Guska), and mergansers (mainly Bijeli ronac and Veliki ronac). Among them it is not uncommon to find a few marine ducks (mainly Patka ledara, Patka crninka and Crna patka). In the lake Patka Kreketaljka, Ćubasti Gnjurac, Veliki Vranac, Krunata Patka, Crvenokljuni Labud and many more often nest.
The reedbeds in the southern part of the lake are often used by Veliki Trstenjak, Bukavac, Trstenjak Rogožar, and Eja Močvarica. In the north Leganj and Šumska šljuka can often be heard during the night. There are large amounts of deciduous forest around Sjöboknäppan which attract Kreja, Mala muharica, Rujnica and Zviždak 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 Mali Galeb and Crna Čigra are sometimes found. The lake holds often Liska, Kokošica, Bijeli ronac, Mali Gnjurac and Žutokljuni Labud 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.
