Description
Straw-necked ibises are large birds, around 59–76 cm (23–30 in) 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; the wings are dark, with an iridescent, multicoloured sheen in sunlight. They have a shiny blue-black back, with a metallic purple, green and bronze glow, and a dark collar. The upper neck is white, as are the underparts and the undertail; their legs are usually red near the top and dark grey toward the feet. Adults have straw-colored feathers on the neck, giving the bird its common name. Their wingspan is about 100–120 cm (39.5–47 in) and weight is generally 1.1–1.5 kg (2.5–3.5 lb). Sexes are similar, although males have longer bills and females have a dark band across their upper breast. Juveniles have duller colors and shorter bills with less curvature, and lack the straw-like plumes on the neck.

Feeding Habits
Straw-necked Ibis's diet consists of invertebrates, insects, mollusks, frogs, crayfish, and occasionally reptiles and rodents. They forage in shallow waters and on land, often consuming pests beneficial to agriculture. They are less opportunistic than related species, rarely scavenging human waste.
Habitat
Straw-necked Ibis predominantly inhabits freshwater environments such as shallow wetlands, edges of swamps, and lagoons, as well as wet or dry grasslands and cultivated pastures. These birds are highly adaptable and can also be found in open forests, irrigation areas, and occasionally human-altered landscapes like gardens, farms, and dumps. They are nomadic, often moving in search of favorable conditions, and though they favor inland habitats, they generally steer clear of arid, coastal, and saline areas. Straw-necked Ibis may roost in trees or reedbeds and construct nests in various wetland vegetation or even on the ground.

General Info
Distribution Area
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 most abundant on the east coast, and are vagrant to New Zealand, Norfolk Island and Lord Howe Island. They are less frequently seen in New Guinea, Indonesia, and occasionally in Tasmania and other islands of the Bass Strait. Found around shallow freshwater wetlands, cultivated pastures, edges of swamps and lagoons, and wet or dry grasslands. They tend to avoid arid and saltwater areas, and coastal mudflats. They are extremely nomadic, and are constantly on the move searching for suitable habitats. They are frequently seen standing on high branches of bare trees, silhouetted against the sky.
