A Study Of The Abundance, Distribution And Daily Activities Of The Australian Raven (Corvus Coronoides) In Urban Wetland Parks, Desiree L. Moon Jan 2005

A Study Of The Abundance, Distribution And Daily Activities Of The Australian Raven (Corvus Coronoides) In Urban Wetland Parks, Desiree L. Moon

Theses : Honours

Habitat destruction as a result of urbanisation has resulted in the population decline of some bird species. However, the Australian Raven (Corvus coronoides), has adapted well to the urban environment and is thriving. Although naturally occurring seasonal food sources are at times restricted in an urban setting, this adaptive species finds alternative food sources. As carrion-eaters this includes roadkill, as well as refuse discarded on the ground and into bins. Coupled with few natural predators, the species enjoys optimal conditions for breeding and survival. This biogeographical study investigated whether seasonal-influxes of populations of ravens cause problems at three urban wetland …


Some Aspects Of The Ecology Of An Urban Corvid : The Australian Raven (Corvus Coronoides) In Metropolitan Perth, P. J. Stewart Jan 1997

Some Aspects Of The Ecology Of An Urban Corvid : The Australian Raven (Corvus Coronoides) In Metropolitan Perth, P. J. Stewart

Theses : Honours

The relatively recent and noticeable increase in abundance and distribution of the Australian Raven (Corvus coronoides) in the Perth metropolitan area, has led to an increase in the amount of problems associated with the bird resulting in a need to quantify its ecology in an urban context. This research documented the abundance and distribution of the raven, possible reasons for its increase, the basic nesting characteristics, peoples attitudes, basic morphology, food items and problems associated with the bird in Perth and Kings Park. These aims were achieved by using observational field data, culled birds, a newspaper questionnaire and Geographic Information …
