Nahan's partridge (Ptilopachus nahani), also known as the Nahan's francolin, is a bird traditionally placed in the family Phasianidae. As suggested by its alternative name, it was formerly believed to be a francolin and placed either in Francolinus or Pternistis, but it is now known that its closest relative is the stone partridge and together may in fact be the only African representatives of the New World quails (Odontophoridae).
At about 25 centimetres (9.8 in) in length, the Nahan's partridge is a relatively small, terrestrial bird with a red eye-ring, legs and base of the bill, brownish upperparts, and black-and-white underparts and head. It is named after Captain Paul-François-Joseph Nahan (1867-1930), a Belgian mercenary who served in the Belgian Congo where he collected the specimen.
This endangered species is found in the rainforests in northeastern DR Congo and western Uganda, and it is threatened by habitat loss and hunting. As of December 2024, the Royal Zoological Society of Scotland is surveying the species' habitat to update its population count. Wikipedia →

Rare
Under 5% of wildlife watchers report a Nahan's Francolin sighting in Semuliki National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 203rd most-seen of the 280 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
August and November–December
In those months about 10% of wildlife watchers report a Nahan's Francolin in Semuliki National Park on a given day, against under 5% in January–July and September–October, the lowest months.
Only Semuliki National Park, in our data
Semuliki National Park is the only park on Wallace's Line with enough records to rate Nahan's Francolin sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Nahan's Francolin is recorded against all the birds logged in Semuliki National Park (13 verified sightings from 2019 to 2026), 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.
