BEHAVIOUR OF NON-BREEDING OR POST-BREEDING WILLIE WAGTAILS Rhipidura leucophrys IN THE WARRUMBUNGLE MOUNTAINS, NEW SOUTH WALES

Posted: 19/07/2021
Author(s): HELEN C. STEVENS

The behaviour of Willie Wagtails Rhipidura leucophrys was observed during late summer in the Warrumbungle Mountains, New South Wales. Eight behaviours were described and time budgeted while diurnal changes in calling and foraging activity were also examined. The time budget revealed that birds were stationary for 54 per cent of time, and spent 15 per […]

ARE WHITE-BROWED BABBLERS TERRITORIAL?

Posted: 19/07/2021
Author(s): PETER G. CALE

White-browed Babblers Pomatostomus superciliosus had overlapping home ranges during the non-breeding season. During the breeding season these home ranges were restricted in area and there was little overlap between groups. There were three types of interaction associated with this spacing behaviour. Foraging interactions involved the aggregation of two or more groups to forage in a […]

LOCAL EXTINCTION AND DECLINE OF BIRDS IN A WOODLAND REMNANT AT INVERLEIGH, VICTORIA

Posted: 19/07/2021
Author(s): L. E. CONOLE

Between 1979-2000 data about the presence or absence of birds were opportunistically collected from a grassy woodland reserve on the edge of the Victorian Volcanic Plain (38°04’S, 144 °03’E). Victoria. Whilst no estimates of absolute abundance were made, the observations over 20 years are representative of avifaunal change during that period. In the last three […]

BURROW OCCUPANCY BY WEDGE-TAILED SHEARWATERS AND FLESH-FOOTED SHEARWATERS ON LORD HOWE ISLAND

Posted: 19/07/2021
Author(s): P. K. DYER

In January 2001 burrow occupancy for two species of Shearwater Puffinus carneipes and Puffinus pacificus was ascertained by using a burrowscope to inspect burrow contents at various sites on Lord Howe Island. Burrow occupancy (and burrow lengths) for Puffinus carneipes and Puffinus pacificus averaged 60 per cent (1.4 m) and 57 per cent (0.8 m) […]

DAY-NIGHT HABITAT USE BY DOUBLE-BANDED PLOVERS Charadrius bicinctus IN THE RICHMOND RIVERESTUARY, NORTHERN NEW SOUTH WALES

Posted: 19/07/2021
Author(s): D. A. ROHWEDER and B. D. LEWIS,

Night and day habitat use by Double-banded Plovers Charadrius bicinctus was studied in the Richmond River estuary, northern New South Wales. Habitat use was documented through direct observation of birds at two intertidal sandflats and by radio-tracking four birds. Comparison of plover density between day and night failed to record a significant difference. However, radio-telemetry […]

AN AUSTRALIAN PELICAN Pelecanus conspicillatus BENEFITS FROM THE BEATING BEHAVIOUR OF A PIED CORMORANT Phalacrocorax varius: A POSSIBLE PRECURSOR TO KLEPTOPARASITISM

Posted: 19/07/2021
Author(s): 0. P. LOVE and C. A. D. SEMENIUK

Food parasitism on pelican species by many groups of birds, especially Larus and Sterna spp. is well known and documented. Although the Pelicanidae exhibit many behavioural and ecological traits. known to facilitate parasitism, few accounts and studies of this feeding strategy by pelicans are known. The following report describes a series of inshore parasitic bouts […]

IDENTIFYING NEST-PREDATOR SPECIES IN A SOUTHERN VICTORIAN WOODLAND USING REMOTELY TRIGGERED CAMERAS AT ARTIFICIAL NESTS

Posted: 19/07/2021
Author(s): LAINIE BERRY

I used remotely trigered cameras placed at artificial nests to identify nest-predator species in Langwarrin Flora and Fauna Reserve, a woodland remnant in southern Victoria. A quail egg placed on top of a microswitch inside a disused bird nest acted as the bait and trigger mechanism for a camera placed nearby. After 220 camera days […]

A DISSOLVING LEG HARNESS FOR RADIO TRANSMITTER ATTACHMENT IN TREECREEPERS

Posted: 19/07/2021
Author(s): VERONICA A. J. DOERR and ERIK D. DOERR

We modified a leg harness designed for radio transmitter attachment in birds so that it could be used in species without long exposed thighs and so that it would automatically fall off after several months. Using this harness, we attached radios to 68 treecreepers (Cl1mactendae) to follow their dispersal movements. Harness life was quite variable […]

ASPECTS OF THE BREEDING BIOLOGY OF THE REEF EGRET Egretta sacra

Posted: 19/07/2021
Author(s): NEIL McKILLIGAN

Reef Egret Egretta sacra nest site characteristics, nest attendance, vocalizations and eggs and chicks are described. Male and female Egrets spend equal time at the nest site at all stages of nesting. Incubation typically involved long sittings (mean about 21.6 hours, standard deviation (s) = 9.46). The timing of feeding and nest attendance is correlated […]

AVIFAUNA OF MOUNT TOMAH BOTANIC GARDENS AND UPPER STOCKYARD GULLY IN THE BLUE MOUNTAINS, NEW SOUTH WALES

Posted: 19/07/2021
Author(s): G. R. FULTON

A survey of diurnal and nocturnal birds of Mount Tomah Botanic Gardens, New South Wales and adjacent native forests was undertaken on one day and night in most months between November 1996 and March 1999. Birds were recorded within the Gardens and along a transect passing through rainforest to open forest at the adjacent Stockyard […]
