Despite the clean-up efforts, once there is an oil spill, it cannot be prevented from causing major damage to wildlife and the environment. All the migrating seabirds like guillemots, puffins, and razorbills are at risk from oil pollution. During migration, they look for calm water where they rest and fish.
