The African pygmy goose (Nettapus auritus) is a perching duck from sub-Saharan Africa. It is the smallest of Africa's waterfowl, and one of the smallest in the world. Though pygmy geese have beaks like those of geese, they are more related to the dabbling ducks and other species called 'ducks'.
It is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. The African pygmy goose was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux in 1785. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Anas aurita in his catalogue of the Planches Enluminées. The type locality is Madagascar. The current genus Nettapus was erected by the German naturalist Johann Friedrich von Brandt 1836. The word Nettapus is from the Ancient Greek... Wikipedia →

With luck
About 10% of wildlife watchers report an African Pygmy-Goose sighting in Mombasa on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 112th most-seen of the 146 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report an African Pygmy-Goose in Mombasa on a given day, against under 5% in June, September and November–March, the lowest months. That is one of Mombasa's driest months, with about 30 mm of rain against 220 mm in May.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most African Pygmy-Goose sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Mombasa, in our data
Mombasa is the only city on Wallace's Line with enough records to rate African Pygmy-Goose sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Anatidae
The closest relatives of the African Pygmy-Goose that you can see in Mombasa (family Anatidae, Ducks, Geese, and Swans) are White-faced Whistling Duck (about 50%) and Egyptian Goose (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the African Pygmy-Goose is recorded against all the birds logged in Mombasa (13 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.
