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. Oil covered seas look calm to birds, and they land on the water by thousands, only to be trapped in the oil and die of starvation. The birds which don't become trapped usually die as well from trying to remove the oil from their feathers, the birds ingest the oil and that usually kills them in a few days.

In my hometown in New Brunswick, finally, traffic lights do not apply to tractors, all terrain vehicles, or pickup trucks, which together account for most vehicles on the road. In fact, were any observant Canadian dropped from an alien space vessel at an unspecified intersection anywhere in this vast land, he or she could almost certainly orient him-or-herself according to the surrounding traffic patterns.
