Sand martin

Sand martins live off of insects which they catch in flight. They build tunnels in bare steep sandy walls, which serve as their nest. Sand martins breed in colonies, so that you often see multiple holes in the wall. Breeding in a steep sandy wall is not without risks: there is great danger of collapsing. The Lauwersmeer is an important breeding area for sand martins.

Sand martins on Texel

Sand martins would sometimes nest on Texel, but it wasn't consistent. There used to be a large colony of around 100 pairs in the 'tuinwallen' (garden walls) on the Hoge Berg. They were also nesting in Dijkmanshuizen and in the vicinity of the Schans and Ceres. Because sand martins often made their nests in old dikes or tuinwallen, they were called 'dike martins' on Texel. In 1994, nests were found in a ground depot in the harbor of Oudeschild. There is now a cement wall in a part of the old sea dike by Minkewaal, specifically designed for sand martins. In 2010, there were at least 11 pairs.

    In order to maintain the colonies, cement walls with holes are sometimes placed against a steep slope. These walls are meant to fight erosion. Examples of these walls are found on Texel and in the Frisan Ureterp.
