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).
Trumpeter Swan (Cygnus buccinator) Weighing from 25-35 pounds when fully grown, the trumpeter swan is the world's largest waterfowl. When fully extended, their wingspan can reach nearly eight feet. The trumpeter is similar in appearance to other white swans, but their foreheads slope evenly to an all black bill. The more common and smaller tundra (whistling) swan usually has a yellow spot in front of its eye.
