BATMOSPHERES: Wild tracks from filming 'The Bat Man of Mexico'

A series of field recordings taken for the BBC2 documentary 'Natural World: The Bat Man of Mexico', narrated by David Attenborough. I recorded these atmospheres in our three month journey across Mexico, from 5km underground, to the high Sierras. As rough offcuts they give as good an idea of any of the auditory landscape of our adventure.
