Human Hunting and the Apparent Suppression of Vocalizations by Male North American Bison During the Rut
Sarno RJ and Grigione MM. Human Hunting and the Apparent Suppression of Vocalizations by Male North American Bison During the Rut. Research Permit and Reporting System
The vociferous bellow of male bison functions as an intrasexual display to deter rival males during the mating season (Berger & Cunningham, 1994). Because mate competition is a fundamental evolutionary process, it is crucial that bison express their full repertoire of natural mating behaviors (Gates et al., 2010). Observations from populations hunted between two and six months/year indicate that bellow (the loud, vociferous roar) rate decreases with increasing hunting frequency.
