These studies suggest that the sound of a walrus bellowing is influenced by seasonal testosterone levels, contingency learning, and breeding displays.
The sound of a walrus bellowing, particularly during breeding displays, is a complex phenomenon influenced by various anatomical and behavioral factors. Research has focused on understanding the mechanisms behind these sounds, their purpose, and the conditions under which they are produced.
Knocking Sounds and Forehead Movements:
Clapping-Induced Cavitation:
Contingency Learning and Sound Variability:
The sound of a walrus bellowing is primarily produced through rhythmic knocking sounds associated with forehead movements and intense clapping-induced cavitation. These sounds are influenced by hormonal levels during the breeding season and can be modified through learned behaviors. The ability of walruses to produce a variety of sounds through contingency learning highlights their vocal plasticity and adaptability.
