These beach nap reprieves serve a social as well as biological purpose for the female seals, as they are able to absorb the nutrients from their hunting themselves before going back to the rookery to nurse the summer pups, and also to get away from the males for a while. But...
However this day ended happily with all mammals in harmony. I always like to add that I strongly discourage people from bothering or approaching wildlife. However in this very isolated area seals and humans are used to seeing one another and these encounters are pretty normal. ☮️
