Ibises (pronounced "EYE-bis-es") are a group of long-legged wading birds in the family Threskiornithidae. They all have long down curved bills, and usually feed as a group, probing mud for food items, usually crustaceans. Most species nest in trees, often with spoonbills or herons. The word ibis comes from Greek, originally borrowed from Ancient Egyptian hib. The Australian White Ibis (Threskiornis molucca) is a wading bird of the ibis family Threskiornithidae, also known as the "Sheep bird". They are widespread in eastern and south western Australia. This ibis occurs in marshy wetlands, often near open grasslands and has become common in Australian east coast city parks and rubbish dumps since 1998, which along with its large size has led to the nickname of "Tip Turkey". The Australian Ibis is known to have a putrid smell of rotting fish or rubbish dumps. Historically rare in urban areas, the Australian White Ibis has immigrated to urban areas of the east coast in increasing numbers since the late 1970s; it is now commonly seen in Wollongong, Sydney, the Gold Coast, Brisbane and Townsville. Debate continues on whether to consider it a pest or vulnerable species. Populations have disappeared from natural breeding areas such as the Macquarie Marshes in northwestern New South Wales. Despite this, the species has been culled in parts of Sydney due to their smell and at times obtrusive nature. This ibis feeds on various fish, frogs and other water creatures, and also insects and garbage. This species has a bald black head and neck and a long black down-curved beak. The body plumage is white with some black feathers near the tail. The legs are dark and red skin is visible on the underside of the wing. The head and neck are feathered in juveniles. The Sacred Ibis was also an object of religious veneration in ancient Egypt, particularly associated with the god, Thoth. This photograph is part of the Imagine Images Collection, hosted by Alamy.
