Over the summer and early autumn we were involved in bird and bat surveys in Northern Germany. By far the commonest large bat we are used to recording in the UK is the Noctule. In contrast the regular large bat in Schleswig-holstein is Serotine, so it was great to see them flying at dusk and start to become familiar with the frequencies they use.
