White (Sacred) Ibis

The Australian white ibis is widespread in eastern, northern and south-western Australia. It occurs in marshy wetlands, often near open grasslands and has become common in Australian east-coast city parks and rubbish dumps in the urban areas 

Historically it was rare in urban areas; the first influx was noted after drought drove birds eastwards in the late 1970s. The urban population further increased after a further period of drought in 1998. The first big colony set up in the Sydney suburband started to cause anxiety in the local community. 

It is estimated the colony was the largest outside the Macquarie Marshes, their natural breeding wetland in inland NSW.
