Lt. j.g. Kyle Carter told The Associated Press that five dead birds have been found.
Carter says three birds are recovering, four were in rehabilitation and released, while another died in rehab. Carter says one dog that got into the oil also was cleaned.
No injuries were initially reported in the Jan. 23 collision that closed the waterway for days.
Houston attorney Charles Livingston says he represents three workers who say they were injured while on a docked vessel allegedly struck by the tanker.
