This week marks the one-year anniversary of the Deepwater Horizon explosion and the world's largest environmental disaster is still having an impact on birds. This week marks the one-year anniversary of the Deepwater Horizon explosion and the massive oil spill that took several weeks to cap is is still having an impact on birds along Louisiana's Coast. Melanie Driscoll with the Audubon Society says there are still remnants of crude from the Macondo Well that continues to impact the bird population. Driscoll says it has been a difficult year for the birds because they have been ingesting oil through their food supply. She also says when birds return to their traditional breeding grounds, they are coming into contact with oil that has re-appeared this spring. According to the latest US Fish and Wildlife report, over 8000 birds collected were either distressed or dead because of the Oil Spill. Driscoll says they are concerned about dispersants that were used to break up the oil. She says large-scale coastal restoration would help make up for bird populations that have been lost.
