Wildlife rescue effort ongoing after California oil spill

Two birds oiled after an undersea pipeline ruptured off the Southern California coast have been treated and released. Birds are often the first wildlife affected by an offshore spill.

Officials have reported 28 oiled birds since the spill off the coast of Orange County. Forty-five birds have been found dead, though not all were visibly oiled.

Katrina Foley, Orange County Supervisor said "We have cleaned 22 birds, there's been two released, but there's also 57 birds that were dead on arrival. So definitely an impact to our wildlife here. They are still patrolling, as you heard, and we'll keep monitoring it."

Michael Ziccardi, Director, Oiled Wildlife Care Network said "Every spill is different. When the one was first reported, as far as some of the initial volumes that were projected, we were very, very concerned. Obviously a very sensitive area, very important. And so that's why we mobilized rapidly and sent a large number of teams out there to do that."

The spill was confirmed on Oct. 2, a day after residents reported a petroleum smell in the area. It leaked at least about 25,000 gallons and the cause remains under investigation.
