Species of bird

The straw necked ibis (Threskiornis spinicollis) is a bird of the ibis and spoonbill family Threskiornithidae. It can be found throughout Australia, New Guinea, and parts of Indonesia. Adults have distinctive straw like feathers on their necks.

Straw necked ibises are large birds, around long, with a bare black head and a long, downcurved black bill. They have a distinctive, highly iridescent plumage, which can appear fairly uniform dirty dark brown in indifferent light; Their wingspan is about and weight is generally .

Straw necked ibises are commonly found throughout Australia, nesting at least occasionally in all mainland states and territories, except in the arid interior. They are less frequently seen in New Guinea, Indonesia, and occasionally in Tasmania and other islands of the Bass Strait. They are frequently seen standing on high branches of bare trees, silhouetted against the sky.

Straw neck ibises are partly migratory: some birds are sedentary, while others make seasonal or erratic movements when water conditions vary. Seasonal migrations are recorded from south eastern and northern Australia, as well as from coast and inland wetlands in central Australia, and across the Torres Strait between north eastern Australia and southern New Guinea. Non breeding migrants arrive in western Australia and leave in autumn, the arrival dates are closely correlated with rainfall during the preceding spring. They typically fly in line or in V formation, reaching high altitudes during long distance movements.

Straw necked ibises feed primarily on aquatic and terrestrial invertebrates, although their diets can vary.

Breeding season is highly variable, mainly influenced by water conditions. In southwestern Australia, it normally occurs from August to December; occasional breeding takes place in the north, but on a very small scale. Breeding has been observed for all months throughout the central and northern regions, usually occurring over the year following heavy rain in some areas. They build a large, rough, cup shaped nest of sticks and trampled plants among reeds, paperbarks, bulrushes, or trees over water. They breed in colonies, often with the Australian white ibis. Nests are used year after year. Clutches vary from 2–5 eggs, with an incubation period of around 24 to 25 days, by both parents. Both parents feed and care for the young, about 35 days after hatching. Feeding is by regurgitation and continues up to two weeks after leaving the nest.
