Category: Issue 1

Author(s): Michael Tarburton

In the lava-tube caves of Samoa the White-rumped Swiftlet Aerodramus s. spodiopygius has a protracted breeding season, laying eggs every month of the year. It builds nests of vegetation and saliva that average 44.7 × 43.7 × 11.8 millimetres in size, 5.1 metres from the cave floor and 5.2 metres from their nearest neighbour. These […]

Author(s): Tim Robinson, David Paull

An understanding of habitat suitability and utility across a given landscape is fundamental in effective threatened species management; particularly in regions where decisions are being made that cause habitat loss. This study develops the use of chewed Allocasuarina littoralis cone fragments as an index of foraging habitat suitability for the Glossy Black-Cockatoo Calyptorhyncus lathami, and […]

Author(s): Errol Nye, Chris Dickman

The range of the Comb-crested Jacana Irediparra gallinacea in New South Wales is thought to have extended southward from the north-eastern coast to near Sydney in the 1930s, and to be receding again now. We review all available atlas records, literature sources, sightings and other records to clarify the species’ distribution and status in New […]

Author(s): Mark Antos, James Fitzsimons, Guy Dutson

There has been little research on the ecological requirements of the Beautiful Firetail Stagonopleura bella, and its habitat preferences are poorly understood. On mainland Australia, the Beautiful Firetail is generally considered to be a bird of coastal regions and the lowlands. This note reports an observation of Beautiful Firetails on the Great Dividing Range at […]

Author(s): Peter Shaughnessy, Sue Briggs

Little Penguins Eudyptula minor have been viewed by tourists at a penguin landing site (Jetty Bay) on Montague Island since 1991. Numbers of penguins coming ashore at Jetty Bay during November in the evening decreased significantly between 1994 and 1998 from approximately 250 to 66 per night, compared with no reduction in numbers coming ashore […]

Category: Issue 2

Author(s): Jarrad Cousin

Nest site selection by the Western Yellow Robin Eopsaltria griseogularis was examined during the 2000 and 2001 breeding seasons in Dryandra Woodland, Western Australia. The average nest height measured 4.1 metres and was found in trees with an average height of 8.2 metres. Nest position generally corresponded to the basal crown height, suggesting an ‘intermediate […]

Is the behaviour of Malleefowl Leipoa ocellata significantly affected by the attachment of radio telemetry equipment?

>> Download Complete PDF | File Size: 289kb

Category: Issue 2

Author(s): Christopher Coombes, Andrea Wilson, Remy Dehaan

The decline of Malleefowl Leipoa ocellata populations across Australia has necessitated field research dependent upon bird identification and location using radiotelemetry equipment. To investigate the effect of radio transmitter attachment this study analysed foraging, moving, preening and resting behaviour of captive Malleefowl with and without radio transmitters attached. Six juvenile Malleefowl were randomly allocated to […]

Time partitioning and substrate use of Red-backed Fairy-wrens Malurus melanocephalus

>> Download Complete PDF | File Size: 322kb

Category: Issue 2

Author(s): Stephen Murphy, Joanne Heathcote, Silvanna Garcia, Sarah Legge

Red-backed Fairy-wrens Malurus melanocephalus are small insectivorous birds that inhabit Australia’s tropical and subtropical savannas. We studied a colour-banded population in the Kimberley, Western Australia, to describe how they partition their time among the main habitat elements within their savanna environment. Eighty-nine focal watches on 29 individuals showed that Red-backed Fairy-wrens spend most of the […]

Category: Issue 3

Author(s): Shaun Thurstans

The nesting habitat of the White-bellied Sea-Eagle Haliaeetus leucogaster was assessed and modelled in a region of south-eastern Tasmania. The selected habitat was assessed by comparing the habitat parameters of 28 nest sites with those of the entire study area. The activity status of nests during the 1997–98 breeding season, and some variables, were measured […]

Category: Issue 3

Author(s): Shaun Thurstans

The Tasmanian Department of Primary Industries and Water maintains a database of raptor nests through its Natural Values Atlas for the purpose of nest-site management (the Tasmanian Raptor Nest Database). During late spring 2003, 79 of the 237 White-bellied Sea-Eagle Haliaeetus leucogaster nests then listed in the database were surveyed. Three nests were found to […]

Author(s): Jason Wiersma, Alastair Richardson

The ranging and foraging behaviour of adult male White-bellied Sea-Eagles Haliaeetus leucogaster, at three marine fish farms and three non-aquaculture sites, were studied in the breeding season (August–December 2000) by radiotelemetry. At non-aquaculture sites (Sea-Eagle nests >8 km from fish farms), areas of Sea-Eagle home ranges averaged 77.2 square kilometres (minimum convex polygon) and 92.2 […]
