When the nor'west wind causes high waves to break over the Canso Causeway and mackerel or billfish are being bashed on the rocks the gulls hang suspended by the wind about 15 to 20 feet above the pavement, waiting for an easy meal. They are high enough to clear small vehicles but suffer a high mortality to the trucks. However they multiply faster than rabbits so are in no danger of extinction.
A crow is always aware of dangerous surroundings but the greedy gulls often forget to look both ways.
