The bugling sound a bull elk makes sounds like a high pitched scream interspersed with grunts. Some people have described the sound as an eerie, guttural and ghostly singing.
Bull elk engage in bugling during the rutting season which takes place from mid-September to mid-October. Bull elk use the sound to convey a wide-range of information. The sound can be a notification to a bull elk's harem that he is close by; a warning to other bull elk to stay away from his cows; or an indication that the bull elk is displeased by his cows' straying too far from him.
