Black Swan

One of my favourite books in finance is Nassim Nicholas Taleb’s "The black swan", a term he popularized to mean "An event or occurrence that deviates beyond what is normally expected of a situation and that would be extremely difficult to predict." The chance sighting of this pair of Black Swan ( Cygnus atratus , the scientific name means ‘a swan attired in black’, ) was something like a 'Black swan' event itself. A series of unplanned events, led my wife and me to a place called Hunter wetland center, where we spotted this pair.
We spent quite sometime, watching this graceful pair. Black swans are naturally found in in the wetlands of south western and eastern Australia and were hunted to near extinction in New Zealand, where they are successfully reintroduced now.  These birds are exclusively herbivores and feed on aquatic plants and algae. The swan is the state emblem of Western Australia and appears on the state flag.
