Normally I do not deploy autonomous recording units, except for scientific monitoring. Why? For me, the best part of sound recording is listening during the recording process (actually, of course, a recording would not have to be done at all to do so).

I was in a marsh area in Mecklenburg-Vorpommern to do a certain job (sound recordings of Whiskered Tern flight calls for my bird ID website birds-in-flight). In the afternoon, I noticed that a thunderstorm came up. Occasions to get thunderstorms recordings without made-noise are rare. So I deployed a second recording kit and continued to do my job.

Thus, this is a rather improvised sound recording of the thunderstorm, including some typical bird sounds of a Brandenburg marshland: White-tailed Eagle, Greylag Goose, Common Tern, Whiskered Tern, Grey Heron, Great Cormorant, Savi's Warbler, Mallard, Eurasian Coot, Gadwall, Black-headed Gull...
