Description

The Black-necked Stork is the only species of stork found in Australia. The distinctive black-and-white waterbird stands an impressive 1.3m tall and has a wingspan of around 2m. The head and neck are black with an iridescent green and purple sheen. The massive bill, short tail and parts of the wings are also black and the long legs are a conspicuous orange-red to bright red. The rest of the body is white. Females have a yellow eye, the males dark-brown. Juvenile birds are generally brown. Black-necked Storks are usually seen singly or in pairs in NSW, occasionally in loose family groups. In flight, they may intersperse their slow, heavy wingbeats with short glides, or soar on thermals. Storks are generally silent.

Distribution

The species Ephippiorhynchus asiaticus comprises two subspecies, E. a. asiaticus in India and south-east Asia, and E. a. australis in Australia and New Guinea. In Australia, Black-necked Storks are widespread in coastal and subcoastal northern and eastern Australia, as far south as central NSW (although vagrants may occur further south or inland, well away from breeding areas). In NSW, the species becomes increasingly uncommon south of the Clarence Valley, and rarely occurs south of Sydney. Since 1995, breeding has been recorded as far south as Buladelah.

Habitat and ecology

  • Floodplain wetlands (swamps, billabongs, watercourses and dams) of the major coastal rivers are the key habitat in NSW for the Black-necked Stork. Secondary habitat includes minor floodplains, coastal sandplain wetlands and estuaries.
  • Storks usually forage in water 5-30cm deep for vertebrate and invertebrate prey. Eels regularly contribute the greatest biomass to their diet, but they feed on a wide variety of animals, including other fish, frogs and invertebrates (such as beetles, grasshoppers, crickets and crayfish).
  • Black-necked Storks build large nests high in tall trees close to water. Trees usually provide clear observation of the surroundings and are at low elevation (reflecting the floodplain habitat).
  • In NSW, breeding activity occurs May - January; incubation May - October; nestlings July - January; fledging from September. Parents share nest duties and in one study about 1.3-1.7 birds were fledged per nest.
  • The NSW breeding population has been estimated at about 75 pairs. Territories are large and variable in size. They have been estimated to average about 9,000ha, ranging from 3,000-6,000ha in high quality habitat and 10,000-15,000ha in areas where habitat is poor or dispersed.
