Mammals in Rezavka Nature Reserve

Thanks to the high variety of its biotopes, Rezavka Nature Reserve is home to mammals dependable on meadows, forests and water areas.

Water Bat (Myotis daubentoni) hunts merely in complete dark. It flies quite quickly, 5–20 cm above the water surface and usually in circles. During spring season it hunts also in vegetation and forests. About 90% of its catch is made of mosquitoes and midges. It can live up to 40 years, however according to Czech records its longest life length does not exceed 28 years.

Eurasian Otter (Lutra lutra) is the best swimmer out of all carnivores. It masters even the most complicated turns with lightness and elegance. An otter chooses its territory at rivers sites leaving urine or excrements mark on their visible places like the sticking-out stones, roots of trees or sand benches.

Western European Hedgehog (Erinaceus europaeus) lives a lonely life except of its reproduction period. It gets active at night when it can be often heard puffing and stamping. During the day it rests in its nest filled with grass and located in hardly accessible places, such as under the stones or in between roots of trees. Though being an omnivore, it prefers animal food, especially invertebrates like slugs, earthworms, beetles and other insect.
