A cubic centimeter (cc) is volume which is a measure of the displacement of the engine. This is the total volume of all the cylinders (no. of cylinders x cross section area x stroke length) 1000 cc = one liter. so a 1500 cc engine is the equivalent displacement of a 1.5 liter engine.
The trumpeter swan (Cygnus buccinator) is a species of swan found in North America. The heaviest living bird native to North America, it also is on average, the largest extant species of waterfowl with a wingspan that may exceed 10 ft (3.0 m).
The feathers on the tundra swan are white. Sometimes the head and neck feathers turn slightly red if the swans are in areas of iron-rich food. Their legs, feet and beak are black and they have a distinctive yellow mark close to the eyes. Baby swans are grey in colour with pink legs, beak and feet.
