“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, Melbourne, the Gold Coast, Brisbane and Townsville. In recent years the bird has also become increasing common in Perth, Western Australia and surrounding towns in south-western Australia. Populations have disappeared from natural breeding areas such as the Macquarie Marshes in north-western New South Wales. Management plans have been introduced to control problematic urban populations in Sydney.”
