Sampling flying bats with thermal and near-infrared imaging and ultrasound recording: hardware and workflow for bat point counts [version 2; peer review: 2 approved]

Bat communities can usually only be comprehensively monitored by combining ultrasound recording and trapping techniques. Here, we propose bat point counts, a novel, single method to sample all flying bats. We designed a sampling rig that combines a thermal scope to detect flying bats and their fligh...
