Acoustically Goosing a Moose

Moose news in a master’s thesis:

Evaluating the Behavioural Response of Moose (Alces alces) to Acoustic Stimuli,” Denice Lodnert, master’s thesis in biology, Swedish University of Agricultural Sciences, 2021. (Thanks to Sven Swahn for bringing this to our attention.) The author reports:

“In this study, I investigated how wild moose (Alces alces) that visited saltlick-stones in the forest responded to different acoustic stimuli: dog barking, human voice and bird calls (owl at night and woodpecker at daytime), compared to when moose are undisturbed by acoustic stimuli….”

“When exposed to any of the three acoustic stimuli, moose took significantly longer to return to a site compared to when they were undisturbed. Longest time to return was after human stimuli. These results suggest that acoustic stimuli may be used in management situations where the aim is to evoke a quick flight response. Acoustic signals may hence serve as a potential measure to prevent ungulate-vehicle collisions.”
