Summary
Hawaiian hoary bat vocalization and visual detection records collected on Hawaii Island, Hawaii, September-October 2014. Bat echolocation was monitored with ultrasonic detectors and bat occurrence and behavior was monitored using thermal surveillance cameras.
Summary
Hawaiian hoary bat vocalization and visual detection records collected on Hawaii Island, Hawaii, September-October 2014. Bat echolocation was monitored with ultrasonic detectors and bat occurrence and behavior was monitored using thermal surveillance cameras.
The objective of the data collection was to determine whether Hawaiian hoary bats seen flying at close range produced detectable echolocation calls and if not, why. We examined flight behavior and acoustic characteristics to determine whether bats seen but not heard briefly stopped echolocating or engaged in behavior that may have resulted in not detecting them acoustically.
