A black swan event is an external event that shocks markets as it deviates beyond what market participants normally would expect. Black swan events are extremely difficult to predict. The term was popularized by Nassim Nicholas Taleb’s book “The Black Swan: The Impact of the Highly Improbable.”

The black swan (Cygnus atratus) is a large waterbird, a species of swan, which breeds mainly in the southeast and southwest regions of Australia. The species was hunted to extinction in New Zealand,[citation needed]but later reintroduced. Some academics cite lack of records during a period of time as evidence that the black swan was hunted to extinction in New Zealand. Within Australia they are nomadic, with erratic migration patterns dependent upon climatic conditions. Black swans are large birds with mostly black plumage and red bills. They are monogamous breeders that share incubation duties and cygnet rearing between the sexes.

Black swans have been introduced to various countries as an ornamental bird in the 1800s, but have escaped and formed stable populations. A small population of Black swans exists on the River Thames at Marlow, and near the River Itchen, Hampshire.

Described scientifically by English naturalist John Latham in 1790, the black swan was formerly placed into a monotypic genus, Chenopis. Black swans can be found singly, or in loose companies numbering into the hundreds or even thousands. Black swans are popular birds in zoological gardens and bird collections, and escapees are sometimes seen outside their natural range.
