An autonomous recording unit deployed in the field to record owl calls.
PhD student Julia Shonfield in Erin Bayne’s lab at the University of Alberta has developed an automated system for detecting owl calls, eliminating the need for researchers to spend nights in the field to survey owls. This new approach combines using audio recorders with a software program that can detect owl calls, called recognizers, and is similarly accurate and far more efficient than other, more traditional methods.
