Description
Kagsmosen is a small protected bog that is squeezed inside by the motorway and buildings. In the 19th century, the swampy and difficult-to-penetrate area was part of the large fortification that encircled Copenhagen with Vestvolden, Utterslev Mose and the defense batteries in the north. Vestvolden lost its significance from 1920 and in 1939 they began to make Kagsmosen more audience-friendly and built paths. The area is now laid out as a park but has retained its character of bog with several peat digging lakes and canals. In certain areas, nature care is carried out for the benefit of animals and plants. Breeding waterfowl include Corcodel mic, Corcodel cu gât roșu, Lebădă de vară, Gâscă de vară, Găinușă de baltă and Lișiță. The area also houses breeding Ciocănitoare pestriță mare, Pițigoi codat, Cocoșar and Privighetoare de zăvoi as well as many songbirds, including Lăcar de stuf and Lăcar de mlaștină. In previous years, the relatively rare Boicuș has bred in the bog. Cojoaică cu degete scurte has been found breeding since 2012. Șorecar comun and Erete de stuf breed in certain years. On Vestvolden up to the bog or in the bog itself, Uliu păsărar often breed.
Kagsmosen is also an excellent bird area for resting and migrating birds. Many ducks, geese and Rață mică, Rață lingurar, Rață moțată and Rață cu cap castaniu can be seen and many of birds of prey. Especially Șorecar comun and also Viespar, and occasionally Gaie roșie, Uliu porumbar, Șorecar încălțat, Codalb, Uligan pescar and Erete vânăt. Cocor annually pass the bog. In addition, many species of waders, larks, swallows, pipers, thrushes, songbirds and finches migrate through the area. The winter season often offers a lot of ducks and Lebădă de iarnă, as well as occasionally Ferestraș mare, herons, raptors and waterfowl. Apart from many different passerines, it is sometimes possible to see Pescărel negru and in certain years flocks of invading Mătăsar. A few years ago Cojoaică cu degete scurte started to overwinter here. Pescăraș albastru is a seldom but regular guest in the area.
In winter, you can visit the nearby locality Harrestrup Å, Islev (Marked with a star on the map), where especially the stretch between Brunevang and the motorway can show both Pescăraș albastru, Pescărel negru and Codobatură de munte.
