Australian Darter

The darters or snakebirds are mainly tropical waterbirds in the family Anhingidae. 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 (A. anhinga) is more commonly known as the Anhinga. It is sometimes called "water turkey" in the southern United States for little clearly apparent reason; 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.

"Anhinga" is derived from the Tupi ajíŋa (also transcribed áyinga or ayingá), which in local mythology refers to a malevolent demonic forest spirit; it is often translated as "devil bird". The name changed to anhingá or anhangá as it was transferred to the Tupi–Portuguese Língua Geral. However, in its first documented use as an English term in 1818, it referred to an Old World darter. Ever since, it has also been used for the modern genus Anhinga as a whole.

The Anhinga (Anhinga 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 the Brazilian Tupi language and means devil bird or snake bird.

It is a cormorant-like bird with an average body length of 85 cm (33 in), a wingspan of 117 cm (46 in), and a mass of 1.35 kg (48 oz). It is a dark-plumaged piscivore with a very long neck, and often swims with only the neck above water. When swimming in this style the name Snakebird is apparent, since only the colored neck appears above water the bird looks like a snake ready to strike.

The Anhinga is placed in the darter family, Anhingidae, and is closely related to Indian (Anhinga melanogaster), African (A. rufa), and Australian (A. novaehollandiae) Darters.

Unlike ducks, the Anhinga is not able to waterproof its feathers using oil produced by the uropygial gland. Consequently, feathers can become waterlogged, making the bird barely buoyant. However, this allows it to dive easily and search for underwater prey, such as fish and amphibians. It can stay down for significant periods.

The Australasian Darter or Australian Darter (Anhinga novaehollandiae) is a species of bird in the darter family, Anhingidae. It is found in Australia, Indonesia, New Zealand, and Papua New Guinea. It weighs around 2.6 kg, spans 85-90 cm in length, and has a lifespan of up to 15 years.

It is closely related to American (Anhinga anhinga), African (Anhinga rufa), and Oriental (Anhinga melanogster) Darters.

Typical habitat is freshwater or brackish wetlands more than 0.5m deep with fallen trees or logs and vegetated banks; less commonly, Darters are found in sheltered saltwater or estuarine environments.
