The African darter (Anhinga rufa), sometimes called the snakebird, is a water bird of Sub-Saharan Africa and Iraq. The African darter is a member of the darter family, Anhingidae, and is closely related to American (A. anhinga), Oriental (A. melanogaster), and Australasian (A. novaehollandiae) darters.
The African darter is 80 cm (31 in) long. Like other anhingas, it has a very long neck. The male is mainly glossy black with white streaking; females and immature birds are browner. The African darter differs in appearance from the American darter most recognisably by its thin white lateral neck stripe against a rufous background colour. The pointed bill prevents confusion with cormorants.
The African darter is found throughout Sub-Saharan Africa wherever large bodies of water occur; overall, the species remains widespread and common. The only non-African subspecies, the Levant darter (Anhinga rufa chantrei), occurred at Lake Amik (Amik Gölü) in south-central Turkey, in the Hula Valley lake and marshes in northern Israel and in the Mesopotamian Marshes of the lower Euphrates and Tigris rivers in southern Iraq.

Rare
Under 5% of wildlife watchers report an African Darter sighting in Johannesburg on a given day, based on 161 verified sightings from GBIF citizen-science data. It is the 88th most-seen of the 219 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May, July–August and October–November
In those months about 10% of wildlife watchers report an African Darter in Johannesburg on a given day, against under 5% in June, September and December–April, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most African Darter sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 11
Of the 11 cities where we can rate African Darter sightings, Johannesburg ranks 7th at under 5%. The best odds are in Dakar (Senegal, about 30%), Cape Town (South Africa, about 30%) and Brazzaville (Republic of the Congo, about 30%).
GBIF citizen-science records
It is estimated from how often the African Darter is recorded against all the birds logged in Johannesburg (161 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.
