In this photo combo, oil stained pelicans and baby pelicans are seen on May 23, 2010, left, on Cat Island, an island that is home to hundreds of brown pelican nests as well at terns, gulls and roseate spoonbills, while it is impacted by oil from the Deepwater Horizon Oil Spill just inside the the coast of Lousiana. In the second photo, taken at the same spot on April 8, 2011, shows the shoreline heavily eroded, and the lush thickets of mangrove trees mostly dead or dying. Biologists from the Louisiana Department of Fish and Wildlife say this is largely because the island was completely overwashed by the oil, and poorly maintained oil booms contributed to the damage as well. less
