Mystery of dead birds in San Francisco Bay Area continues

SAN FRANCISCO (AP) - San Francisco Bay Area officials have begun laboratory tests and necropsies on dead birds found coated with a mysterious substance that looks and feels like dirty rubber cement.

More than 100 birds have been found along the shorelines in Alameda, Foster City, San Leandro, and Hayward, east of San Francisco. The goo covers their feathers and the birds lose their ability to insulate themselves and they freeze to death.

The San Francisco Chronicle reports that preliminary tests by California Department of Fish show the gray goo is not a petroleum-based substance or an organic product like vegetable or fish oil. At least 300 birds have been brought in by International Bird Rescue volunteers.

Wildlife officials hope to identify the gummy material this week, but it could be longer before they discover the source of the pollution.
