Every ten yards we’d find another ten bodies of these sweet little things.” Cassin’s auklets are tiny diving seabirds that look like puffballs. They feed on animal plankton and build their nests by burrowing in the dirt on offshore islands. Their total population, from the Baja Peninsula to Alaska’s Aleutian Islands, is estimated at somewhere between 1 million and 3.5 million. Last year, beginning about Halloween, thousands of juvenile auklets started washing ashore dead from California’s Farallon Islands to Haida Gwaii (also known as the Queen Charlotte Islands) off central British Columbia. Since then the deaths haven’t stopped. Researchers are wondering if the die-off might spread to other birds or even fish. More
