I suspect Domoic Acid influence.  As you probably know, there is a
massive domoic acid outbreak along the southern and central California
coast affecting everything from seabirds to whales. One of the effects
of domoic acid toxicosis is loss of directional sense, so affected
animals wander far from their habitats. Other effects lead to
malnutrition.  Brown Pelicans in SoCal have been hard-hit by this outbreak.

We had Dr. Padraig Duignan on The Ecology Hour talking about domoic acid
last fall, explaining what it is and how it works:
