Bearded seal (Erignathus barbatus)

Jan 19, 2023, 09:51 AM

Bearded seals produce typical downsweept trills underneath the Arctic sea ice. Calls are produced by males in spring to defend underwater territories. Specific trajectories and areas are patrolled by males under the ice while producing these acoustic displays. Calls are thought to attract potential mates and repel potential rival males.
