SANTA BARBARA, Calif., March 7 (UPI) -- Naturally seeping oil off the Southern California coast is taking a toll on seabirds, with dozens ending up coated in crude oil and tar, wildlife officials say.
The naturally occurring oil bubbles up every winter but wildlife rescuers in recent weeks have seen an unusual influx of oiled seabirds stranded on the shore, with the region's main rehabilitation center in San Pedro having treated 140 birds since Jan. 1, the Los Angeles Times reported Wednesday.
