Mystery of incident that inspired 'The Birds' solved?

Dan Vergano in USA Today: Whodunit? A final mystery surrounding the work of film legend Alfred Hitchcock— what triggered the crazed bird flocks that helped inspire his 1963 thriller The Birds— appears solved by scientists.

Dying and disoriented seabirds rammed themselves into homes across California's Monterey Bay in the summer of 1961, sparking a long-standing mystery about the cause among marine biologists. The avian incidents sparked local visitor Hitchcock's interest, along with a story about spooky bird behavior by British writer Daphne du Maurier.

"I am pretty convinced that the birds were poisoned," says ocean environmentalist Sibel Bargu of Louisiana State University in Baton Rouge. She led a team finding that naturally occurring toxins appear to have been the culprit.

Call it the Case of the Poisoned Plankton. Looking at the stomach contents of turtles and seabirds gathered in 1961 Monterey Bay ship surveys, Bargu and colleagues have now found toxin-making algae were present in 79% of the plankton that the creatures ate. In particular, the team finds in the current Nature Geoscience journal that the leading toxin inside the plankton was a nerve-damaging acid, which causes confusion, seizures and death in birds...
