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 […]
Read MoreNest-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 […]
Read MoreThis 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 […]
Read MoreMethods typically used to catch small- to large-sized waterbirds in tropical Australia are outlined. Detail is provided on a number of commonly used techniques, including licensing requirements, required levels of expertise, logistical support and general costs. Further, a case study of two capture methods (cannon-netting and cage-traps) used to secure waterbirds in Kakadu National Park, […]
Read MoreThis 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 […]
Read MoreBetween 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 […]
Read MoreInformation is presented on the locations where Black-necked Storks Ephippiorhynchus asiaticus australis have been observed in New South Wales since 1790, utilising records from: published data, museums, bird atlases and personal communications. The distribution in New South Wales has not changed significantly since 1790. Its breeding distribution is restricted to the coastal plains from the […]
