Summary

In this study, we create and evaluate a protocol to estimate the density, which can be used to estimate the abundance of terrestrial sound-producing animals from single automatic sound recorders. The protocol uses cue rates from the target species as well as sampling conditions and an estimate of the distance of the individual to the recorder based on the power of the sound. We applied our protocol to estimate the density of two Hawaiian forest bird species (Hawaiˊi ˊamakihi, Chlorodrepanis virens and ˊōmaˊo, Myadestes obscurus) on the island of Hawaiˊi, USA. We validate our approach by comparing our density estimations with others calculated at the same stations using a traditional point-transect distance sampling method based on [...]

Purpose

Obtaining accurate information on the distribution, density, and abundance of animals is an important first step towards their conservation. Methodological approaches using automatic sound recorders for species that communicate acoustically are gaining increased interest because of their advantages over traditional sampling methods. This study presents a relatively simple but effective protocol to estimate animal density using single automatic sound recorders that can be adapted to any sound emitting terrestrial animal.
