Mangrove Gerygones Gerygone levigaster were banded at six sites in the Greater Brisbane region, Queensland over 5.5 years, and at three sites in Darwin, Northern Territory, over 8-9 years. The species was highly sedentary in both regions, and no movements were recorded among sites at either location. In Darwin, males were larger than females in […]
Food exploitation patterns in forest bird assemblages have: (1) management significance, with respect to maintaining the resources required to support these assemblages under various forest usage regimes, and (2) theoretical interest, regarding the roles of interspecific and intersexual competition in shaping such assemblages. The foraging behaviour of the bird assemblage of a vertically stratified Mountain […]

The threatened Black- breasted Button-quail Turnix melanogaster is thought to have an omnivorous diet comprising seeds and invertebrates; however, very little study has been undertaken to confirm or refute this claim. A thorough understanding of a species’ diet is required for its effective conservation management. To determine the species’ diet, T. melanogaster faeces were collected […]

No alleged recorded calls of Buff-breasted Button-quail Turnix olivii have been directly linked to observations of an individual vocalising. Recorded calls have proven as elusive as a photograph of a live bird. The best descriptions of calls date back to the 1920s. Using spectrograms, we analysed the call structure of ‘booming’ calls recorded on automated […]

Several different survey techniques are commonly used to assess the richness and abundance of birds. These methods can vary with respect to the likelihood of detecting species with different habits or characteristics and their effectiveness in different vegetation structures. It is advisable, therefore, to test the effectiveness of different methods for specific vegetation types and […]
