Nature Notes: Sooty Shearwater

Have you ever wondered what inspired Alfred Hitchcock’s movie The Birds? The Santa Cruz Sentinel reported that thousands of crazed sooty shearwaters were regurgitating anchovies, flying into buildings and dying in the streets in August 1961. This event, along with a short story written by Daphne du Maurier, inspired the thrilling movie. Scientists examined the stomach contents of sea turtles and shorebirds from samples that were saved at Scripps Institute of Oceanography and almost 80 percent of the plankton the animals were eating were diatoms that produced domoic acid. This toxin causes confusion, disorientation, scratching, and even death.
