Caroline Rowley is the director of the Endangered Primate Research Center (EPRC) located in Cuc Phuong National Park (CPNP) Vietnam. She and her team are using SM4BAT FS and Echo Meter Touch 2 Pro ultrasonic recorders to monitor lorises in CPNP including those that have been rescued from wildlife trafficking, rehabilitated, and released into the wild.
They hope to improve the release process through increased knowledge of the wild loris population in the park and their habitat preferences.
SM4BAT FS recorders will be paired with camera traps for long term studies to estimate the population density and gauge increases or decreases of the loris population in CPNP over time.This will help direct and validate the release program and improve the tracking capability for released lorises.
Echo Meter Touch 2 Pro recorders will be used while radio tracking the lorises. The tagged animals will be tracked acoustically also, increasing the chances of locating them, and gathering information on other individuals that might be in the area.
Unseen for 75 years, the Blue-eyed Ground-dove, one of the rarest birds in the world, was rediscovered in 2015 in Botumirim Brazil. Biologist Albert Aguiar and his coworkers at SAVE Brasil’s team are working to save this species and are using acoustics to help. Kaleidoscope’s clustering technology allows Albert to analyze almost 1500 hours of recordings per year, looking for the rare calls of the dove. These recordings will then allow him to understand the current population and the consequences of removing eggs or adults for captive breeding or translocation. He is also looking for population trends and predators. Clustering is a perfect tool for his work as it will help to find these rare calls among all the other sounds of the nature reserve where these animals live.
