International Bird Rescue releases last seabird coated in mystery goo

FAIRFIELD, Calif. (KGO) -- A renowned Bay Area bird rescue center has released the last of the birds they've nursed back to health after hundreds were discovered this year covered in mystery goo. The bird was released Wednesday in Sausalito.

In January, birds were discovered in the San Francisco Bay with a mystery goo coating them. The substance still has not been identified and 158 birds died.

The birds were nursed back to health at the International Bird Rescue in Fairfield. The non-profit spent $150,000 to care for the birds. An account has been set up to help with funding the bird rescue effort.

California has funding in place to aid in case of oil spills, but does not provide for unknown substances. A new bill has made it out of committee to help change that.
