Many neotropical rainforest mammals are shy, cryptic or nocturnal, and it is only possible to detect their presence through their distinctive vocalizations. This is an audio guide to these mammal sounds, featuring the calls of 109 species or sub-species, including almost all species of primates and commonly-encountered larger mammals. Information on the behavioural context for each call and where it was recorded is included in an accompanying booklet. This also cites the relevant pages in the matching field guide, which is published separately.
