Two key questions for anyone starting out are:

  • What do I need to start recording nocturnal bird migration?
  • How much do I need to spend?

As a minimum you’ll need a microphone to place outside and something that digitally saves the sounds detected by the microphone. Then you’ll need a computer on which to review the recordings and a pair of headphones for listening to individual bird detections. There are countless permutations of microphone–recorder, but the right option for you will depend on what you already have, where you want to record and your underlying motivation (ranging from detecting garden ticks to making high quality recordings). Answering these questions will determine how much you need to spend.

Below is an outline of some of the popular options for nocmig recording, arranged roughly in order of increasing cost (assuming you already own a smartphone and desktop PC/laptop). Some of the information is based on personal experience and some on discussion with other nocmiggers. To see examples of how some of these solutions have been used, see the gallery. To see/hear recordings from some different kit, see the Comparisons page. There will be options we haven’t yet considered – please let us know what we’ve missed via the Contact form.
