Heart rate response of carrion crows to an auditory stimulus used for bird pest control

Abstract

In this study, we used a miniature electrocardiogram (ECG) data-logger and evaluated the physiological response of carrion crows (Corvus corone) to an auditory repellent stimulus. Three carrion crows had an average heart rate of 243 bpm before they were exposed to the auditory stimulus. Their heart rates increased significantly to 302 bpm on initial exposure to the auditory stimulus and decreased gradually as the stimulus was repeated.
