The Australian Black Swan ( Cygnus atratus ) is completely black except for the white flight feathers on its wings ; the chicks of black swans are light grey in colour, and the South American Black-necked Swan has a black neck.

The Mute Swan and Black-necked Swan have a lump at the base of the bill on the upper mandible.

There is some evidence that the Black-necked Swan is migratory over part of its range, but detailed studies have not established whether these movements are long or short range migration.

The Black-necked Swan ( Cygnus melancoryphus ) is the largest waterfowl native to South America.

The Black-necked Swan was formerly placed in monotypic genus, Sthenelides.

The wetlands created by the Great Chilean Earthquake like Carlos Anwandter Nature Sanctuary in Cruces River have become important population centers for the Black-necked Swan.

The Black-necked Swan, like its nearest relatives the Black and Mute Swan is relatively silent.

Widespread and common throughout its habitat, the Black-necked Swan is evaluated as Least Concern on the IUCN Red List of Threatened Species.

They are also on average smaller than other geese, though some very large taxa are known, which rival the Swan Goose and the Black-necked Swan in size.

The Black-necked Crane ( Grus nigricollis ) is a medium-sized crane in Asia that breeds on the Tibetan Plateau and winters mainly in remote parts of India and Bhutan.

Cygnets may ride on their parent's back for longer trips into deeper water, but Black Swans undertake this behaviour less frequently than Mute and Black-necked Swans.

Like all grebes, the Black-necked Grebe nests on the water's edge, since its legs are set very far back and it cannot walk well.

In 2004 and 2005 thousands of Black-necked Swans in the Carlos Anwandter Nature Sanctuary in Chile died or migrated away following major contamination by Valdivia Pulp Mill located on the Cruces River which feeds the wetlands.

: Generally similar to Black-necked Stilt, but black on head and neck more extensive, usually extending below the eye.

Black-necked Storks fed almost exclusively on fish in wetlands located inside managed, protected areas in Australia and India.

The Black-necked Weaver feeds on insects and vegetable matter.

In 1932 a pair of Black-necked Grebes bred at the lake, the only occasion on which this species has been recorded breeding in Somerset.

Black-necked Cranes forage on the ground in small groups, often with one bird acting as a sentinel.

The Black-necked Crane is evaluated as Vulnerable on the IUCN Red List of Threatened Species.

It is home to a wide variety of birds when wet, including Black-necked Stilts, Roseate Spoonbills, Great Egrets, American White Ibis, and many others.

Two species, White and Black Stork, reach Europe and western temperate Asia, while one species, Oriental Stork, reaches temperate areas of eastern Asia, and one species, Black-necked Stork, is found in Australasia.

However, a cladistic analysis of the forelimb skeleton found it highly similar to the Great Crested Grebe and unlike the Painted Buttonquail ( now known to be a basal charadriiform lineage ), the Black-necked Stilt ( a more advanced charadriiform ), or the Limpkin ( a member of the Grui suborder of Gruiformes ), namely in that its dorsal condyle of the humerus was not angled at 20 °– 30 ° away from long axis of the humerus.

This combination of colouration ultimately distinguishes it from similar species in Asia, like the Hooded and Black-necked Cranes.

The Black-necked Grebe ( Podiceps nigricollis ) known in North America as the Eared Grebe, is a member of the grebe family of water birds.

The Black-necked Grebe is long.

Black-necked Grebes of the nominate subspecies P. n. nigricollis in the cooler temperate regions of the Old World also winter further south, with many European birds moving to the Mediterranean area.

The Black-necked Grebe is an excellent swimmer and diver, and pursues its prey underwater, eating mostly fish as well as small crustaceans, aquatic insects and larvae.

Most sources recognize 6 species in 2 genera, although the White-backed and Hawaiian stilts are occasionally considered subspecies of the Black-necked Stilt.
