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 Озерная чайка, three species of grebe breed here ( Малая поганка, Чомга and Серощекая поганка), together with many waterfowl. Waders include Чибис and Малый зуёк. Речная крачка breed here and can be seen foraging throughout the summer. Passerines include Обыкновенная кукушка, Обыкновенный соловей and many warblers. The biggest attraction for birdwatchers is probably breeding Обыкновенный ремез. 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 ( Чирок-трескунок , Чирок-свистунок , Шилохвость , Свиязь , Серая утка and Широконоска ) can be observed. Raptors include a fair number of Канюк and smaller numbers of Обыкновенный осоед, together with infrequent visitors such as Красный коршун, Зимняк, Орлан-белохвост, Полевой лунь, Болотный лунь, Скопа (often seen foraging) – and with some luck Дербник and Сапсан. Большая выпь has been observed on a few occasions. If there are easterly winds flocks of Серый журавль may appear. Many waders ( Кулик-сорока , Чибис , Малый зуёк , Большой улит , Черныш , Фифи , Перевозчик, Бекас og af og til Вальдшнеп ).
In addition, Клуша and Морская чайка and even Чеграва are occasionally seen. Also sparrows, a lot of larks, pipers, wagtails, swallows, thrushes and finches rest and pull in and over the bog. Усатая синица is seen occasionally. Обыкновенная горихвостка , Луговой чекан, Каменка, Серая мухоловка, Мухоловка-пеструшка, Обыкновенный жулан and Обыкновенная чечётка and Горная чечетка are seen regularly. Дроздовидная камышевка 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: Лебедь-кликун, Гуменник and Канадская казарка. In periods of frost, one may be lucky enough to see Водяной пастушок foraging at close range in Sømose Å or even a Гаршнеп. In some years there can be invasions of Рябинник, Белобровик or Свиристель, 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.
