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 čajka smejivá, three species of grebe breed here ( potápka malá, potápka chochlatá and potápka červenokrká), together with many waterfowl. Waders include cibík chochlatý and kulík riečný. rybár riečny breed here and can be seen foraging throughout the summer. Passerines include kukučka obyčajná, slávik veľký and many warblers. The biggest attraction for birdwatchers is probably breeding kúdeľníčka lužná. 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 ( kačica chrapačka , kačica chrapka , kačica ostrochvostá , kačica hvizdárka , kačica chripľavka and kačica lyžičiarka ) can be observed. Raptors include a fair number of myšiak hôrny and smaller numbers of Včelár lesný, together with infrequent visitors such as haja červená, myšiak severský, orliak morský, kaňa sivá, kaňa močiarna, kršiak rybár (often seen foraging) – and with some luck sokol kobec and sokol sťahovavý. bučiak veľký has been observed on a few occasions. If there are easterly winds flocks of žeriav popolavý may appear. Many waders ( lastúrničiar strakatý , cibík chochlatý , kulík riečný , kalužiak sivý , kalužiak perlavý , kalužiak močiarny , kalužiačik malý, močiarnica mekotavá og af og til sluka hôrna ).
In addition, čajka tmavá and čajka morská and even čegrava veľkozobá are occasionally seen. Also sparrows, a lot of larks, pipers, wagtails, swallows, thrushes and finches rest and pull in and over the bog. fúzatka trstinová is seen occasionally. žltochvost hôrny , pŕhľaviar červenkastý, skaliarik sivý, muchár sivý, muchárik čiernohlavý, strakoš obyčajný and stehlík čečetka and stehlík hnedkavý are seen regularly. trsteniarik veľký 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: labuť spevavá, Hus siatinná and bernikľa veľká. In periods of frost, one may be lucky enough to see chriašteľ vodný foraging at close range in Sømose Å or even a močiarnička tichá. In some years there can be invasions of drozd čvíkota, drozd červenkavý or chochľač severský, and many colourful finches.
