The Purple Swamphen (Porphyrio porphyrio) is a "swamp hen" in the rail family Rallidae. Also known locally as the pūkeko, African Purple Swamphen, Purple Moorhen, Purple Gallinule or Purple Coot. From its French name talève sultane, it is also known as the sultana bird. This chicken-sized bird, with its large feet, bright plumage and red bill and frontal shield is easily recognizable in its native range.
There are 13 or more subspecies of the Purple Swamphen (depending on the authority) which differ mainly in plumage color.
The species makes loud, quick, bleating and hooting calls, which are hardly bird-like in tone. It is particularly noisy during the breeding season. Despite being clumsy in flight it can fly long distances, and it is a good swimmer, especially for a bird without webbed feet.
The Purple Swamphen prefers wet areas with high rainfall, swamps, lake edges and damp pastures. The birds often live in pairs and larger communities. It clambers through the reeds, eating the tender shoots and vegetable-like matter. They have been known to eat eggs, ducklings, small fish and invertebrates such as snails. They will often use one foot to bring food to their mouth rather than eat it on the ground. Where they are not persecuted they can become tame and be readily seen in towns and cities.
Evidence from Pliny the Elder and other sources shows that the Romans kept Purple Swamphens as decorative birds at large villas and expensive houses. They were regarded as noble birds and were among the few birds that Romans did not eat.
The common name in New Zealand, used by Maori for the subspecies P. p. melanotus, is the Māori language name Pūkeko. The New Zealand Purple Swamphen was held in high regard as a chiefly pet in New Zealand and in Samoa, where it is called "manuali'i" (literally, "chiefly bird").
The Purple Swamphen was introduced to North America in the late 1990s due to avicultural escapes in the Pembroke Pines, Florida area. State wildlife biologists attempted to eradicate the birds, but they have multiplied and can now be found in many areas of southern Florida. Ornithological authorities consider it likely that the swamphen will become an established part of Florida's avifauna.
