BAY AREA (KRON)– The state Department of Fish and Wildlife has determined the mysterious goo that killed hundreds of birds on the East Bay shoreline is a mixture of non-petroleum-based fats or oils.
However, the department has yet to determine what the source of the substance is and how it got into bay waters.
The substance has gotten onto around 500 seabirds and was extremely difficult to clean off of the birds.
Officials were able to capture 323 birds covered in the substance alive.
Most of the birds were taken to the International Bird Rescue in Fairfield to recover.
The rest of the birds were already found dead.
Despite the bird rescue’s effort, 102 birds died at the rescue.
As of last week, about 100 seabirds had been released.
