Research on avian vocalisations has traditionally focused on male song produced by oscine
passerines. However, accumulating evidence indicates that complex vocalisations can …

The accelerating loss of biodiversity worldwide demands effective tools for monitoring
animal populations and informing conservation action. In habitats where direct observation …

It is commonly assumed that aerial insectivorous bats in the tropics respond to moonlight
intensity by decreasing their foraging activity during bright nights due either to an increase in …

The extrinsic factors that most influence animal activity are weather and light conditions,
which can be assessed at hourly, monthly, and even lunar-cycle timescales. We evaluated …

Due to the increasing scale of farms, it is increasingly difficult for farmers to monitor their
animals in an automated way. Because of this problem, we focused on a sound technique to …

Monitoring wildlife abundance across space and time is an essential task to study their
population dynamics and inform effective management. Acoustic recording units are a …

Tropical forests are facing threats that may affect the dynamics of seed dispersers which
participate in the forest regeneration. To implement appropriate conservation programs, it …

Bird vocal activity is affected by endogenous and exogenous factors. Owl surveys are mainly
based on the detection of nocturnal calls, and therefore, the impact of exogenous factors on …

Current knowledge regarding the vocal behavior in tropical non-passerines is very limited.
Here, we employed passive acoustic monitoring to study the vocal activity of the white-tipped …
