This is nonsense. A classic case of mistaking an anecdote for data.

There's lots of year-to-year variation in currents which affect life in the ocean. In turn, the birds which depend on seafood vary tremendously.

For example, two years ago Pelagic Cormorants had tremendous problems with their food source off of Northern California. So the Cormorants moved around seeking food. Santa Clara County, which normally goes years without seeing this species, saw dozens.

If you want to find out if something is actually going on, go talk to the ornithologists who monitor the nesting sites for the seabirds.
