What do you do up in the tower all day, but obsess?
Watch the waves crashing on the rocks below.
Watch the seagulls and pelicans flock around beneath you as they take the navigational turn around the bluffs.
The harbor seals look like lifeless grey slugs on the rocks, while the seas crash around them. It must be exhausting trying to fight against rough seas, so the cleverer of the seals hunkers down. When they are in the water, they are moving very quickly and with great agility. When they are out of the water, they are exhausted and relieved for the chance to relax on a nice safe rock. It would be difficult for a predator to sneak up on them to grab a quick snack, and if something tasty swims by them as they are saving up their calories they can motivate themselves to roll or dive off and give chase.
