Aims: The aim of this case study is to observe and analyse, in an attempt to understand, the behaviour of the Australian White Ibis (Threskiornis molucca), and understand how these behaviours may have attributed to its successful urban lifestyle. Multiple locations were selected to observe any changes in behaviour that may be the result of a different environment. Introduction: Background on the Australian White Ibis The Australian White Ibis is a wading bird that belongs to the family Threskiomithidae family. It is a cousin of the African Sacred Ibis (Threskinornis aethiopicus), which is native to Africa and the Middle East.

In 1970 Holyoak proposed that the three species shared too similarities to be considered different species and should all be identified as T. aethiopicus. However in 1991 Lowe and Richards published an assessment of the plumage of each species, highlighting their differences as well as their similarities. This was then followed by a chromosome study which showed that each of the three species posses as different …show more content…

These birds are considered a nuisance in tourist areas or areas where there are often large gatherings because of their smell is found to be unpleasant by most people. These birds have been known to scavenge for food in bins, around people eating, or even snatching food off of people while they're eating. These feeding behaviours are likely what allows such a bird to thrive in urban areas. The Australian White Ibis has a varied diet, eating both terrestrial and aquatic invertebrates as well as feasting on human scraps. The birds seem to favour crayfish and mussels, which the bird collects using their long beaks. During their breeding season (usually from August to November), Ibis create a shallow bowl-like nest from sticks, grasses and reeds. These nests are typically located near a body of water. Each breeding female will lay a clutch of 2-3 dull-white eggs and incubate them for 21-23 days. Hatchlings of this species are altricial and take 2 days to
