The distribution of a flute-like dialect in territorial songs of the Superb Lyrebird Menura novaehollandiae in the New South Wales North Coast and New England Tableland Bioregions

Posted: 08/05/2019
Publication: Corella
Category: Volume 43
Author(s): Hollis Taylor, Vicki Powys, and Carol Probets

On-site recordings were made and field data obtained on the territorial songs of the Superb Lyrebird Menura novaehollandiae at 100+ sites in forests of the New South Wales North Coast and New England Tableland Bioregions during winter from 2009-2014. Songs were categorized as either ‘flute-like’ or not flute-like, and the two song types are compared. […]

Faecal analysis reveals the insectivorous diet of the Black-breasted Button-quail Turnix melanogaster

Posted: 08/05/2019
Publication: Corella
Category: Volume 43
Author(s): Patrick Webster, Allan Lisle and Peter Murray

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 […]

Unravelling the mysteries of the Buff-breasted Button-quail Turnix olivii: a possible booming call revealed

Posted: 08/05/2019
Publication: Corella
Category: Volume 43
Author(s): Geoffrey C. Smith and Michael T. Mathieson

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 […]

Effectiveness of transects, point counts and area searches for bird surveys in arid Acacia shrubland

Posted: 08/05/2019
Publication: Corella
Category: Volume 43
Author(s): Bruce A. Pascoe, Christine A. Schlesinger, Chris R. Pavey and Stephen R. Morton

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 […]

A method for investigating Rufous Scrub-birds using automated recording and rapid, semi-automated data analysis

Posted: 08/05/2019
Publication: Corella
Category: Volume 43
Author(s): Alan Stuart and Margaret O’Leary

Calls made in a Rufous Scrub-bird Atrichornis rufescens territory were recorded for periods of about seven days using an automated recording unit. We developed a method using Raven Pro to scan these recordings for scrub-bird chipping calls for rapid analysis. We present a preliminary analysis of field data showing that the use of this analytical […]

Reproductive effort of urban Little Ravens: nest site selection and brood defence

Posted: 08/05/2019
Publication: Corella
Category: Volume 43
Author(s): Alan Lill

Altricial birds’ reproductive effort typically includes choosing an optimal nest site and protecting it in some manner against species constituting a threat to successful breeding. Pairs of urban Little Ravens Corvus mellori nested predominantly in tall eucalypts with a broader, denser canopy and fewer neighbouring trees of similar or greater height than control trees 100 […]

Reproductive effort of urban Little Ravens: the nest attendance regime

Posted: 08/05/2019
Publication: Corella
Category: Volume 43
Author(s): Alan Lill

Parental care is a major component of reproductive effort in altricial birds, but the time allocated to it is patchily documented for Corvus species, including Little Ravens Corvus mellori. Nest attendance by Little Ravens was documented in urban Melbourne to: (a) assess its extent and potential to entail costs sufficient to significantly reduce its obvious […]

Assessment of band recoveries for four Australian falcon species

Posted: 08/05/2019
Publication: Corella
Category: Volume 43
Author(s): S. J. S. Debus, Jerry Olsen and Candice Larkin

Available band recoveries from 1958 to 2015 were analysed for the Nankeen Kestrel Falco cenchroides (n = 97, recovery rate 3%), Brown Falcon F. berigora (n = 78, recovery rate 6%), Australian Hobby F. longipennis (n = 13, recovery rate 11%) and Peregrine Falcon F. peregrinus (n = 97, recovery rate 8%). Nankeen Kestrels banded […]

Assessment of avian site fidelity in arid Acacia shrubland based on a ten-year mark-recapture study in central Australia

Posted: 08/05/2019
Publication: Corella
Category: Volume 43
Author(s): Bruce A. Pascoe, Christine A. Schlesinger, Chris R. Pavey and Stephen R. Morton

Mark-recapture surveys of bird communities were conducted at five Acacia shrubland sites near Alice Springs, central Australia, between 2001 and 2011. The primary objective was to examine the levels of site fidelity displayed by individuals to provide insight into local bird community dynamics that cannot be ascertained by visual surveying. Approximately 1800 birds from 50 […]
