Description
Sømosen is situated west of the suburb of Herlev, next to Lautrupparken. The green area, of which one third is a park with grass and scattered bushes, is neighbour to many large institutions and popular for a short walk in the open air. The bog itself was formed in a hollow after the last Ice Age. It is drained by the stream of Sømose Å. The bog was previously very overgrown, but during the 1980’s the municipality of Ballerup carried out an extensive re-establishment project, opening up large stretches of water and recreating islands and islets where birds can breed without being disturbed. Sømosen has developed into a little oasis with a rich birdlife. In addition to the large colony of Karabağ martı, three species of grebe breed here ( Küçük batağan, Bahri and Kızılboyunlu batağan), together with many waterfowl. Waders include Kızkuşu and Küçük halkalı cılıbıt. Sumru breed here and can be seen foraging throughout the summer. Passerines include Guguk, Benekli bülbül and many warblers. The biggest attraction for birdwatchers is probably breeding Çulhakuşu. However, the tits have unfortunately not nested here the last few years, although they can sometimes be spotted in the area in spring.
Sømosen is also an excellent locality for migrating and staging birds both spring and autumn. Geese, ducks ( Çıkrıkçın , Çamurcun , Kilkuyruk , Fiyu , Boz ördek and Kaşıkgaga ) can be observed. Raptors include a fair number of Şahin and smaller numbers of Arı Şahini, together with infrequent visitors such as Kızıl Çaylak, Paçalı şahin, Akkuyruklu kartal, Gökçe delice, Saz delicesi, Balık kartalı (often seen foraging) – and with some luck Boz doğan and Gök doðan. Balaban has been observed on a few occasions. If there are easterly winds flocks of Turna may appear. Many waders ( Poyrazkuşu , Kızkuşu , Küçük halkalı cılıbıt , Yeşilbacak , Yeşil düdükçün , Orman düdükçünü , Dere düdükçünü, Su çulluğu og af og til Çulluk ).
In addition, Karasırtlı Martı and Büyük Karasırtlı Martı and even Hazar sumrusu are occasionally seen. Also sparrows, a lot of larks, pipers, wagtails, swallows, thrushes and finches rest and pull in and over the bog. Bıyıklı baştankara is seen occasionally. Kızılkuyruk , Çayır taşkuşu, Kuyrukkakan, Benekli sinekkapan, Kara sinekkapan, Kızılsırtlı örümcekkuşu and Huş isketesi and Küçük Huş İsketesi are seen regularly. Büyük kamışçın has visited the bog for a single year.
In the winter months many wildfowl can be seen and visitors from northern Scandinavia may turn up: Ötücü kuğu, Tarla kazi and Kanada Kazı. In periods of frost, one may be lucky enough to see Su kılavuzu foraging at close range in Sømose Å or even a Küçük su çulluğu. In some years there can be invasions of Tarla ardıcı, Kızıl ardıç or İpekkuyruk, and many colourful finches.

Access
If using public transport, Sømosen is most easily reached from Copenhagen by taking bus 350S and getting off at Københavns Teknikum (the Copenhagen University College of Engineering) in Ballerup. One can also take the local 167/168 bus from Herlev Station (get off at Herlev Stadium and walk down Rørløkken to Sømosen). If coming by car, it is possible to park on Vingekrogen. There is a bird observation tower in the south-east corner of the bog, and in the north-east corner is a jetty which is very useful as a look-out post.
