The western swamphen (Porphyrio porphyrio) is a species of swamphen in the rail family Rallidae, one of the six species of purple swamphen. This chicken-sized bird, with its large feet, bright plumage and red bill and frontal shield is easily recognisable in its native range. It used to be considered the nominate subspecies of the purple swamphen, but is now recognised as a separate species. The western swamphen is found in wetlands in Spain (where the largest population lives), Portugal, southeastern France, Italy (Sardinia and Sicily) and northwestern Africa (Morocco, Algeria and Tunisia).
The western swamphen was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He placed it with the coots in the genus Fulica and coined the binomial name Fulica porphyrio. The specific epithet porphyrio is Latin for a swamphen. The word is from Ancient Greek πορφυριον (porphurion) meaning "swamphen" which in turn is from πορφυρα (porphura) meaning "purple". The species had been described in 1678 by the English ornithologist Francis Willughby under that Latin name Porphyrio and English name "purple water-hen". Linnaeas specified... Wikipedia →

Possible
About 30% of wildlife watchers report a Western Swamphen sighting in Chennai on a given day, based on 2,509 verified sightings from GBIF citizen-science data. It is the 27th most-seen of the 223 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
January
In that month about 40% of wildlife watchers report a Western Swamphen in Chennai on a given day, against about 20% in April to June, the lowest months. That is one of Chennai's driest months, with about 15 mm of rain against 290 mm in November.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Western Swamphen sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
10th of 77
Of the 77 cities where we can rate Western Swamphen sightings, Chennai ranks 10th at about 30%. The best odds are in Visakhapatnam (India, about 40%), Indore (India, about 40%) and Durg (India, about 40%).
Same family: Rallidae
The closest relatives of the Western Swamphen that you can see in Chennai (family Rallidae, Rails, Gallinules, and Coots) are White-breasted Waterhen (about 40%), Common Moorhen (about 30%) and Eurasian Coot (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Western Swamphen is recorded against all the birds logged in Chennai (2,509 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
