In Mapuche accounts the chonchon is the result of sorcery: either a person (commonly described in some versions as a woman) who enters into a contract with a sorcerer or an initiated kalku who undergoes a voluntary transmutation. Sources describe a procedure in which anointment of the throat with a magical cream facilitates the removal of the head, which then flies away as the chonchon. The chonchon is linked to kalku networks and contracts with an evil spirit (wekufe) and may be created by or serve such practitioners.
Described as a human head that becomes animate and airborne: the head is said to be adorned with feathers and to have unusually large ears that serve as wings, enabling flight. It detaches from the body and flies at night; accounts emphasize a terrifying appearance but note ordinary people may not see it.
Sources state the chonchon flies at night (particularly moonless nights) to attend secret gatherings or covens at a supposed subterranean location called the reni. It is said to possess the magical powers of a kalku or to be used by kalku to carry out malevolent acts, including drinking the blood of the sick or sleeping. Its cry is an omen often interpreted as predicting the impending death of a loved one. Visibility is contested in accounts: some state only other sorcerers or those seeking such power can see it while ordinary people hear its cry.

A Japanese yōkai-class apparition associated with humans (most often women) who display an uncanny bodily anomaly: either an extremely extendable neck or a head that detaches and moves independently (the latter often called nukekubi). Appears in classical kaidan collections and Edo-period encyclopedias and is variously framed in sources as a supernatural being, an illness, or the soul wandering during sleep.
