Rosie,
Just a word of warning. If you're going to use your recorder for natural soundscapes you may find the levels are quite low on playback on the H2. Don't be tempted to use the 'normalizer' in the machine it takes far too long. Download your recordings into your PC in something like Cool Edit (or whatever) or Audacity, reduce the peaks and then normalize, it will take a much shorter time.
