Even if BP's top kill procedure works this week, the damage has been done.
On Sunday, some brown pelicans coated in oil couldn't fly away on Barataria Bay of the Louisiana coast. All they could do was hobble. Their usually brown and white feathers were jet black, and eggs were glazed with rust-colored gunk.
When wildlife officials tried to rescue one of the pelicans, the birds became spooked. Officials weren't sure whether they would try again, and U.S. Fish and Wildlife spokeswoman Stacy Shelton said it is sometimes better to leave the animals alone than to disturb their colony.
Pelicans are especially vulnerable to oil because they dive into the water to feed. They could eat tainted fish and feed it to their young, or they could die of hypothermia or drown if their feathers become soaked in oil. Just six months ago, the birds had been removed from the federal endangered species list.
