Description

Lake Sommen is quite deep and most of the lake is ice-free all-winter. During this period large amounts of Goosander, Common Goldeneye and Great Crested Grebe winter in Sommen. Sometimes in the hundreds. Among these Tufted Duck, Mute Swan, Whooper Swan, Eurasian Coot, and Common Gull can often be found. The lake is also home to quite a few rarer wintering birds like Black-throated Diver, Red-breasted Merganser, Golden Eagle, Common Scoter, Velvet Scoter, Common Kingfisher, Red-throated Diver and Black-headed Gull.

During the spring migration marine ducks can be found in the lake. At the same time Red-throated Diver, and Black-throated Diver, arrive at the lake. Black-throated Diver breeds in the lake while Red-throated Diver feeds in the lake and breeds in small neighbouring lakes. The rare White-billed Diver has been seen. Sommen archipelago hosts large colonies of Common Tern, Common Gull, Black-headed Gull, European Herring Gull, Grey Heron and Great Cormorant. Among these some rare birds like Lesser Black-backed Gull, and Arctic Tern can be seen.

The large decidous forests around sommen especially on Torpön host plenty of quite rare birds like: Red-breasted Flycatcher, Lesser Spotted Woodpecker, Nutcracker, and Long-eared Owl. Around Sommen there is also old conifer forests around which support large populations of woodpeckers. Eurasian Wryneck, Eurasian Green Woodpecker, Black Woodpecker, Lesser Spotted Woodpecker, Eurasian Three-toed Woodpecker (very rare), Great Spotted Woodpecker and White-backed Woodpecker (extinct in the area) have all been recorded. Other otherwise rare forrest birds found here are: Hazel Grouse Western Capercaillie, Black Grouse (Rocks mosse), and Nutcracker.

During the autumn birds can be seen migrating through the lake. Most common are the doves, finches, terns, and waders. At Rocks mosse Black Grouse and Western Capercaillie breed. At Visskvarn there are rapids where White-throated Dipper, and Grey Wagtail can be seen.
