Author(s): Jerry Olsen, Susan Trost, David Judge

Between 1996 and 1999 we measured the distance from the nest that four Southern Boobooks called using ‘territorial boobook’ and ‘bray’ calls, the latter used only by females. Median distances from the nest tree that they used ‘territorial boobook’ calls were 175 metres and 250 metres for two females, 210 metres and 525 metres for […]

Author(s): Natalie Doerr

This study documents the annual survival rate of bower-owning male Great Bowerbirds Ptilonorhynchus nuchalis in Townsville, Queensland. The mean survival rate of bower-owning males was 84 per cent from 2003 to 2007. The estimate of survival is slightly lower than that recorded for bower-owning males of three other species (range: 90 – 93%). Lower estimates […]

Author(s): Jeff Hardy

This paper reviews the current and historic distribution of the Grey Grasswren Amytornis barbatus barbatus in New South Wales, its abundance and its prospects for survival in this State. None of its habitat is protected under conservation legislation and its remaining habitat suffers from continued degradation by grazing domestic stock. The options for habitat protection […]

Nest-site Characteristics of the Wedge-tailed Eagle Aquila audax in Southern Victoria

>> Download Complete PDF | File Size: 146kb

Category: Issue 2

Author(s): Adam Foster, Rob Wallis

Nest-site characteristics of the Wedge-tailed Eagle Aquila audax were investigated in the outer Melbourne region of Victoria in 1999–2000. Nests (n = 20) were found in a range of local habitats (isolated trees to forest) and forest or woodland types. Nests averaged 12.6 metres above the ground (5–20 m, n = 14) and were placed […]

Category: Issue 2

Author(s): Adam Foster, Rob Wallis

The breeding diet of the Wedge-tailed Eagle Aquila audax was investigated in the Bacchus Marsh district of southern Victoria in 1999–2000, by collection and analysis of prey remains and pellets from six territories (including five active nests, all of which fledged young). The eagles’ diet (n = 111 prey items) consisted of 95.5 per cent […]

Author(s): Michelle Hall, Stephen Murphy, Roy Churchwell, Olga Milenkaya

Skutch (1961) described helping behaviour in birds, including cases where non-breeding individuals assist with rearing offspring of others of the same species (cooperative breeding), as well as cases where individuals feed young of a different species (interspecific feeding). Cooperative breeding is common in some groups of birds, and may arise because ecological constraints limit opportunities […]

Author(s): Nicholls, Nicholls

In August 1990 we began a small study to investigate the potential movements of the introduced Common Myna Sturnus tristis in the urban environment of Canberra. An initial report on a movement of 9.5 kilometres by an individual bird over a period of nearly three years was reported by Nicholls et al. (1996). The present […]

Category: Issue 3

Author(s): Geering

The Regent Honeyeater has been the subject of intensive study and conservation effort over the past decade and a half. Until now, there has been no guide to accurately age and sex Regent Honeyeaters in the field. Being able to age and sex birds potentially provides data on population structure and dynamics. In particular, it […]
