Three top Obama administration officials are returning to the Gulf Coast to monitor the massive oil spill that seems to have no end in sight _ the devastation underscored by oil-stained pelicans and their eggs on an island where hundreds of the birds nest, AP reported. On Saturday, the pelican colony off Louisiana's coast was awash in oil. An Associated Press photographer saw several birds and their eggs coated in the ooze. Nests rested in mangroves precariously close to the crude that had washed in. Workers had surrounded the island with oil-absorbing booms, but puddles of oil had seeped through the barrier. Anger with the government and BP PLC, which leased the rig and is responsible for the cleanup, has boiled over as more wildlife and delicate coastal wetlands are tainted. U.S. Environmental Protection Agency chief Lisa P. Jackson was headed Sunday to Louisiana, where she planned to visit with frustrated residents. -- SPA
