Except for the sound of the breakers and occasional challenges by young male seals, the rookery is rather quiet during the months of March through November. Beginning in late November, however, with the arrival of the adult males who compete for dominance, vocalizing begins in earnest. Then, beginning in late December as pups appear on the beach, their chatter and the scolding of their mothers add to the level and variety of sound. Finally, mating begins in late January and extends into early March with new contributions to the noise level. Click on the pictures to listen in on these conversations.
