Physical description Click here for a physical description White-necked Herons are tall herons with a completely white head and neck. Their wings and mantle are gark-grey, with a purple sheen, especially during the breeding season, when they have conspicuous spiny ("lanceolate") plumes on the back. In eclipse they lose their plumes and the colours of the plumage become duller in general. They have a grey bill, legs and feet. Juveniles have grey scalloped plumage at the front (neck, breast and belly). The back is duller grey than in adults.

Taxonomy, classification See White-necked Heron at Wikipedia .

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the White-necked Heron is available HERE . White-necked Herons breed only in Australia, but may migrate North to eastern Indonesia and southern New Guinea outside the breeding season. In Australia, White-necked Herons are found over most of the continent, including Tasmania, with the exception of the major deserts of the interior, in the eastern half of WA, the western half of SA and the south-eastern corner of the NT. On the fringes of their range towards the arid interior they are present only when there is sufficient surface water, normally after major rainfall events. White-necked Herons are only found in freshwater shallows, along rivers and creeks and around lakes and farm dams and irrigation dams, but also in ephemeral wetlands, such as e.g. ditches or flooded paddocks.

Sightings Click here for sighting information As is the case also for White-faced Herons, there is no need to go far for seeing a White-necked Heron; there are plenty along water edges almost all through the Australian continent, both inland and along the sea shores. White-necked Herons are regularly found by us in a variety of wetlands in inland NSW, including e.g. ephemeral lakes such as Goran Lake, 30 km South of Gunnedah, NSW, when full. In October 2016 a pair was found breeding at Yarrie Lake, near Wee Waa, NSW. Since then, White-necked Heron nests have been found by us at this location semi-regularly. C. Hayne reports White-necked Herons breeding regularly at Whittaker's Lagoon, 20 km West of Moree, NSW. J. Greaves reports spotting White-necked Herons at Yellow Water billabong, Kakadu NP, NT, in November 2014. White-necked Herons have also been reported to us from various locations in near-coastal QLD, and also from inland QLD, e.g. Currawinya NP, near Hungerford, QLD. R. Plumtreereports spotting White-necked Herons regularly in East Gippsland, VIC. P. Brown reports spotting a White-necked Heron along the Arnhem Highway, in the Top End of the NT, in August 2018. M. Eaton reports finding a White-necked Heron at Bagama, QLD, near the tip of Cape York peninsula, in August 2019. M. Mearns found a White-necked Heron in Diamantina NP, QLD, in August 2019. A White-necked Heron was found by C. Pears at the golf course in Margaret River, WA, in October 2018.

Breeding information

Breeding season: Sep - Jan

Eggs: 4

Incubation period: ca. 30 days

Fledging age: 42 - 49 days

White-necked Herons are colonial breeders. The breeding season of White-necked Herons can be longer, inland especially when there is plenty of water (and thereby prey).

Nest

"bungobittah", "lar", "malunna", "jindi" [bundjalung] = nest [Aboriginal]

Type: Basket

Material: Sticks

Height above ground: 10 - 25 m

Note that in water or on islands in lakes/dams White-necked Herons can nest much lower than they would do in trees in areas that can be accessed. We have found nests as low as 1-2 m above ground, with juveniles sitting on branches of low shrubs barely above water level.

Behaviour

Social behaviour: ?

Mobility: Dispersive

Elementary unit: Solitary

Although normally solitary, White-necked Herons can be found in large numbers where the pickings are rich - every single dark dot on the sky in this photo is a White-necked Heron

Food, Diet

All egrets and herons prey on aquatic creatures in fresh water or estuaries (fish, frogs, snakes or crustaceans). We are not aware of any specialisation of White-necked Herons.
