Allen's gallinule (Porphyrio alleni), formerly known as the lesser gallinule, is a small waterbird of the family Rallidae. Its former binomial name is Porphyrula alleni. Porphyrio is the Latin for "swamphen", and alleni, like the English name, commemorates British naval officer Rear-Admiral William Allen (1792–1864).
Allen's gallinules are found year-round in marshes and lakes in Sub-Saharan Africa. It has occurred as a vagrant in several European countries, and is the only purely Sub-Saharan bird species to reach Great Britain. They are similar in size to the only slightly larger water rail. The Allen's gallinule has a short red bill, greenish back and purple upperparts. They have red legs with long toes, and a short tail which is white with a dark central bar underneath. Breeding males have a blue frontal shield, which is green in the female. Immature Allen's gallinules are sandy brown with a buff undertail. The downy chicks are black, as with all rails. They nod their heads as they swim.
Allen's gallinules are very secretive in the breeding season, particularly in the dense swamps they favour, and are... Wikipedia →

With luck
About 10% of wildlife watchers report an Allen's Gallinule sighting in N'Djamena on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 51st most-seen of the 70 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
July and September
In those months about 20% of wildlife watchers report an Allen's Gallinule in N'Djamena on a given day, against under 5% in March and April, the lowest months. Those are among N'Djamena's wettest months, with about 110 mm of rain a month against almost none in January. June, August and October–December have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Allen's Gallinule sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 5
Of the 5 cities where we can rate Allen's Gallinule sightings, N'Djamena ranks 3rd at about 10%. The best odds are in Mombasa (Kenya, about 30%) and Ouagadougou (Burkina Faso, about 10%).
GBIF citizen-science records
It is estimated from how often the Allen's Gallinule is recorded against all the birds logged in N'Djamena (9 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.
