In April of 2003, the Bouchard Barge 120 struck bottom and spilled its load of No. 6 fuel oil into Buzzards Bay in southeastern Massachusetts, killing more than 200 wintering loons. LPC coordinated the efforts of a number of conservation organizations to track the dispersal and fate of loons not killed outright by the spill. Our data will be instrumental in determining restitution to help replace loons lost in the Buzzards Bay oil spill.
