Demolition of the old Bay Bridge, which was damaged in the Loma earthquake in northern California 25 years ago, is being delayed by about 800 birds that refuse to leave a portion of the old span that connects Oakland and San Francisco.
The double crested cormorant is not on the Endangered species list though it is recognized as a "protected" species under the migratory bird act of 1918.
Officials have tried expensive decoys, bird recordings, and fake nests in an attempt to lure the cormorants 100 feet to the new span, but their efforts have failed.
The estimated cost so far for the delay is $33 million - $40,000 per bird. The costs could skyrocket if the birds are still entrenched in February when it's time for them to start laying eggs.
