Description

Lake Sommen is quite deep and most of the lake is ice-free all-winter. During this period large amounts of Ferestraș mare, Rață sunătoare and Corcodel mare winter in Sommen. Sometimes in the hundreds. Among these Rață moțată, Lebădă de vară, Lebădă de iarnă, Lișiță, and Pescăruș sur can often be found. The lake is also home to quite a few rarer wintering birds like Cufundar polar, Ferestraș moțat, Acvilă de munte, Rață neagră , Rață catifelată, Pescăraș albastru, Cufundar mic and Pescăruș râzător.

During the spring migration marine ducks can be found in the lake. At the same time Cufundar mic, and Cufundar polar, arrive at the lake. Cufundar polar breeds in the lake while Cufundar mic feeds in the lake and breeds in small neighbouring lakes. The rare Cufundar cu cioc alb has been seen. Sommen archipelago hosts large colonies of Chiră de baltă, Pescăruș sur, Pescăruș râzător, Pescăruș argintiu, Stârc cenușiu and Cormoran mare. Among these some rare birds like Pescăruș negricios, and Chiră polară can be seen.

The large decidous forests around sommen especially on Torpön host plenty of quite rare birds like: Muscar mic, Ciocănitoare pestriță mică, Alunar, and Ciuf de pădure. Around Sommen there is also old conifer forests around which support large populations of woodpeckers. Capîntortură, Ghionoaie verde, Ciocănitoare neagră, Ciocănitoare pestriță mică, Ciocănitoare de munte (very rare), Ciocănitoare pestriță mare and Ciocănitoare cu spate alb (extinct in the area) have all been recorded.

During the autumn birds can be seen migrating through the lake. Most common are the doves, finches, terns, and waders. At Rocks mosse Cocoș de mesteacăn and Cocoș de munte breed. At Visskvarn there are rapids where Pescărel negru, and Codobatură de munte can be seen.
