Anhinga africana

The African darter (Anhinga rufa), sometimes called the snakebird, is a water bird of sub-Saharan Africa and Iraq. [1]

Taxonomy

The African darter is a member of the darter family, Anhingidae, and is closely related to American (Anhinga anhinga), Oriental (Anhinga melanogaster), and Australasian (Anhinga novaehollandiae) darters.

Description

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.

Distribution

The African darter is found throughout sub-Saharan Africa wherever large bodies of water occur; overall the species remains widespread and common. [1]

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 Euphrat es and Tigris rivers in southern Iraq. The Turkish population disappeared during the 1930s and the Israeli population during the drainage of the Hula in the 1950s. In Khuzestan, 110 birds were counted in 1990, but the subspecies was feared extinct as a result of oil spills during the Gulf War and the drainage of the Mesopotamian Marshes that followed it. [2] However, a small population was documented in the Hawizeh Marshes in 2007. [3] The drainage of the marshes was interrupted and reversed after the Iraq War. [2]

This species builds a stick nest in a tree and lays 3–6 eggs. It often nests with herons, egrets and cormorants.

It often swims with only the neck above water, hence the common name snakebird. This, too, is a habit shared with the other anhingas. It feeds on fish, which it catches by diving.

Unlike many other waterbirds the feathers of the African darter do not contain any oil and are therefore not waterproof. Because of this, the bird is less positively buoyant and its diving capabilities are enhanced. After diving for fish, the feathers can become waterlogged. In order to be able to fly and maintain heat insulation, it needs to dry its feathers. Thus the African darter is often seen sitting along the waterside spreading its wings and drying its feathers in the wind and the sun along with cormorants, which may share its habitat.

<span class="mw-page-title-main">Anhinga</span> Species of bird

The anhinga, sometimes called snakebird, darter, American darter, or water turkey, is a water bird of the warmer parts of the Americas. The word anhinga comes from a'ñinga in the Brazilian Tupi language and means "devil bird" or "snake bird". The origin of the name is apparent when swimming: only the neck appears above water so the bird looks like a snake ready to strike. They do not have external nares (nostrils) and breathe solely through their epiglottis.

<span class="mw-page-title-main">Darter</span> Family of birds

The darters, anhingas, or snakebirds are mainly tropical waterbirds in the family Anhingidae, which contains a single genus, Anhinga. There are four living species, three of which are very common and widespread while the fourth is rarer and classified as near-threatened by the IUCN. The term snakebird is usually used without any additions to signify whichever of the completely allopatric species occurs in any one region. It refers to their long thin neck, which has a snake-like appearance when they swim with their bodies submerged, or when mated pairs twist it during their bonding displays. "Darter" is used with a geographical term when referring to particular species. It alludes to their manner of procuring food, as they impale fishes with their thin, pointed beak. The American darter is more commonly known as the anhinga. It is sometimes called "water turkey" in the southern United States; though the anhinga is quite unrelated to the wild turkey, they are both large, blackish birds with long tails that are sometimes hunted for food.

<span class="mw-page-title-main">Cormorant</span> Family of aquatic birds

Phalacrocoracidae is a family of approximately 40 species of aquatic birds commonly known as cormorants and shags. Several different classifications of the family have been proposed, but in 2021 the IOU adopted a consensus taxonomy of seven genera. The great cormorant and the common shag are the only two species of the family commonly encountered in Britain and Ireland and "cormorant" and "shag" appellations have been later assigned to different species in the family somewhat haphazardly.

<span class="mw-page-title-main">Purple heron</span> Species of bird

The purple heron is a wide-ranging species of wading bird in the heron family, Ardeidae. The scientific name comes from Latin ardea "heron", and purpureus, "coloured purple". It breeds in Africa, central and southern Europe, and southern and eastern Asia. The Western Palearctic populations migrate between breeding and wintering habitats whereas the African and tropical-Asian populations are primarily sedentary, except for occasional dispersive movements.

<span class="mw-page-title-main">Oriental darter</span> Species of bird

The Oriental darter is a water bird of tropical South Asia and Southeast Asia. It has a long and slender neck with a straight, pointed bill and, like the cormorant, it hunts for fish while its body is submerged in water. It spears a fish underwater, bringing it above the surface, tossing and juggling it before swallowing the fish head first. The body remains submerged as it swims, and the slender neck alone is visible above the water, which accounts for the colloquial name of snakebird. Like the cormorants, it has wettable feathers and it is often found perched on a rock or branch with its wings held open to dry.

The white-breasted cormorant is much like the widespread great cormorant and if not a regional variant of the same species, is at least very closely related. It is distinguished from other forms of the great cormorant by its white breast and by the fact that subpopulations are freshwater birds. Phalacrocorax lucidus is not to be confused with the smaller and very different endemic South Australian black-faced cormorant, which also is sometimes called the white-breasted cormorant.

The Mesopotamian Marshes were drained in Iraq and to a smaller degree in Iran between the 1950s and 1990s to clear large areas of the marshes in the Tigris-Euphrates river system. The marshes formerly covered an area of around 20,000 km2 (7,700 sq mi). The main sub-marshes, the Hawizeh, Central, and Hammar marshes, were drained at different times for different reasons.

The Hammar Marshes are a large wetland complex in southeastern Iraq that are part of the Mesopotamian Marshes in the Tigris–Euphrates river system. Historically, the Hammar Marshes extended up to 4,500 km2 (1,700 sq mi) during seasonal floods. They were destroyed during the 1990s by large-scale drainage, dam and dike construction projects. Since 2003, they are recovering following reflooding and destruction of dams.

Lake Amik or the Lake of Antioch was a large freshwater lake in the basin of the Orontes River in Hatay Province, Turkey. It was located north-east of the ancient city of Antioch. The lake was drained during a period from the 1940s–1970s.

The Central or Qurna Marshes are a large complex of wetlands in Iraq that, along with the Hawizeh and Hammar marshes, make up the Mesopotamian Marshes of the Tigris–Euphrates river system. Formerly covering an area of around 3000 square kilometres, they were almost completely drained following the 1991 uprisings in Iraq and have in recent years been reflooded.
