It is one of the crowned pigeons and is very similar to other crowned pigeon species, the crowned pigeon , the red-breasted crowned pigeon and the Sclaters red-breasted crowned pigeon .
Fan pigeons were shown at London Zoo as early as 1848. Numerous zoological gardens now keep fan pigeons in their tropical halls, European zoos are endeavoring in a conservation breeding program to ensure the survival of the species that is classified by the IUCN as near threatened - potentially endangered. In the zoo animal husbandry, breeding is now very regular.
