Ecologists Sound out New Solution for Monitoring Cryptic Species
ScienceDaily (Nov. 28, 2009) — Ecologists have at last worked out a way of using recordings of birdsong to accurately measure the size of bird populations. This is the first time sound recordings from a microphone array have been translated into accurate estimates of bird species’ populations. Because the new technique, reported in the British Ecological Society’s Journal of Applied Ecology, will also work with whale song, it could lead to a major advance in our ability to monitor whale and dolphin numbers.
