Sivholm



Swans’ nests on Sivholm.

Sivholm, at the end of Kattinge Vig, is a small, low islet close to the shore, and is almost covered in reeds. In 1954 Freddy Jensen found swans breeding on Ringø for the first time, and shortly afterwards the first colony, a sizeable one, was established on Sivholm. Previously swans had only bred in lakes and bog land, but the 1926 ban on hunting led to such an increase in population that they began to nest on islands in the Danish fjords. In the 1970s several pairs bred on Kattinge Lake, where they no longer breed regularly. Nowadays only the odd few pairs nest on Sivholm. Greylag geese, coots and a few other species also breed there.
