The African black duck (Anas sparsa) is a species of duck of the genus Anas. It is genetically closest to the mallard group, but shows some peculiarities in its behavior and (as far as they can be discerned) plumage; it is accordingly placed in the subgenus Melananas pending further research.
The African black duck is a black duck with pronounced white marks on its back, a dark bill, and orange legs and feet. A purpish-blue speculum is often visible, especially in flight. It lives in central and southern Africa. It is also known as the black river duck, or (A. s. leucostigma) West African black duck or Ethiopian black duck. It is a medium-sized duck, with a length of 48–57 cm (19–22 in). The male is larger than the female.
The African black duck is mainly found in eastern and southern sub-Saharan Africa from South Africa north to South Sudan and Ethiopia with outlying populations in western equatorial Africa, in southeast Nigeria, Cameroon and Gabon.
It is a very shy and territorial duck. It is usually seen in pairs or small flocks. It breeds throughout the year in different areas. Incubation is about 30 days by... Wikipedia →

With luck
About 10% of wildlife watchers report an African Black Duck sighting in Nairobi on a given day, based on 102 verified sightings from GBIF citizen-science data. It is the 84th most-seen of the 234 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.
February, May–June and August–December
In those months about 10% of wildlife watchers report an African Black Duck in Nairobi on a given day, against under 5% in January, March–April and July, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most African Black Duck sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 8 cities where we can rate African Black Duck sightings, Nairobi ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Johannesburg (South Africa, about 10%) and Lilongwe (Malawi, about 10%).
GBIF citizen-science records
It is estimated from how often the African Black Duck is recorded against all the birds logged in Nairobi (102 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.
