Common Grasshopper Warbler

      Locustella naevia

      Information

      The song of the Common Grasshopper Warbler, a monotonous, mechanical whirring reel, which is mostly heard at dusk, may easily be mistaken for the chirping of a cricket or a grasshopper. The male sings in such a way that it is difficult to spot. If the Common Grasshopper Warbler is flushed, it quickly skulks in dense vegetation moving like a mouse. If it does fly, it only flies a short distance close above ground in order to disappear in the vegetation again.
