The biggest library of bat sounds has been compiled to identify bats from their calls in Mexico -- a country which harbours many of Earth's species and has one of the highest rates of extinction and habitat loss.
An international team led by scientists from UCL, University of Cambridge and the Zoological Society of London (ZSL), developed the reference call library and a new way of classifying calls to quickly and accurately identify and differentiate between bat species.
It is the first time automatic classification for bat calls has been attempted for a large variety of species, most of them previously noted as hard to identify acoustically.
The researchers say the method can be used to monitor biodiversity change and complete information on bat species distributions in remote and understudied regions in Mexico. It could also be expanded for use in other areas across the Neotropics, which incorporates South and Central America, and the Caribbean Islands and Florida.
