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).
A mute swan, which may have personally lost the power of flight due to extreme weight, was found to have weighed 23 kg (51 lb). The sarus crane is the tallest flying bird alive, at up to 1.8 m (5.9 ft) tall, standing about as high as Argentavis due to its long legs and neck.
