As spill grows, oil soaks delicate marshes, birds

As officials approached to survey the damage the Gulf oil spill caused in coastal marshes, some brown pelicans couldn't fly away Sunday. All they could do was hobble.

Several pelicans were coated in oil on Barataria Bay off Louisiana, their usually brown and white feathers now jet black. Pelican eggs were glazed with rust-colored gunk, and new hatchlings and nests were also coated with crude.

It is unclear if the area can even be cleaned, or if the birds can be saved. It is also unknown how much of the Gulf Coast will end up looking the same way because of a well that has spewed untold millions of gallons of oil since an offshore rig exploded more than a month ago.

"As we talk, a total of more than 65 miles of our shoreline now has been oiled," said Louisiana Gov. Bobby Jindal, who announced new efforts to keep the spill from spreading.

A mile-long tube operating for about a week has siphoned off more than half a million gallons in the past week, but it began sucking up oil at a slower rate over the weekend. Even at its best the effort did not capture all the oil leaking, and the next attempt to stanch the flow won't be put into action until at least Tuesday.

With oil pushing at least 12 miles into Louisiana's marshes and two major pelican rookeries now coated in crude, Jindal said the state has begun work on chain of berms, reinforced with containment booms, that would skirt the state's coastline.

Jindal, who visited one of the affected nesting grounds Sunday, said the berms would close the door on oil still pouring from a mile-deep gusher about 50 miles out in the Gulf. The berms would be made with sandbags and sand hauled in; the U.S. Army Corps of Engineers also is considering a broader plan that would use dredging to build sand berms across more of the barrier islands.

At least 6 million gallons of crude have spewed into the Gulf, though some scientists have said they believe the spill already surpasses the 11 million-gallon 1989 Exxon Valdez oil spill off Alaska as the worst in U.S. history.
