Mystery substance killing birds in Alameda County

FAIRFIELD, Calif. (KGO) -- Dozens of seabirds have been found on the San Francisco Bay's eastern shores covered in a viscous, mystery substance that destroys feather waterproofing, which can cause hypothermia and death. 20 birds have already died.

East Bay Regional Park District staffers notified International Bird Rescue's San Francisco Bay center about the problem late Friday. A total of 60 seabirds, including Surf Scoters, Buffleheads and Common Goldeneyes had been transported to International Bird Rescue in Fairfield.

The birds have been found in Crab Cove in Alameda, the Hayward shoreline and the San Leandro Marina.

International Bird Rescue is paying for all emergency care costs at this time and is seeking public support.
