Box 137, Heidelberg, Victoria 3084, Australia. Abstract Feral cat eradication is planned for Dirk Hartog Island (620 km2), which is the largest island off the Western Australian coast. The island, in the Shark Bay World Heritage Property, once supported at least 13 species of native mammals but only three species remain. Since the 1860s, Dirk Hartog Island has been managed as a pastoral lease grazed by sheep and goats. Cats were probably introduced by early pastoralists and became feral during the late 19th century. Dirk Hartog Island was established as a National Park in November 2009, which provides the opportunity to eradicate feral cats and reconstruct the native mammal fauna. A 250 km2 pilot study was conducted on the island to assess the efficacy of aerial baiting as the primary technique for the eradication campaign. Initially, cats were trapped and fitted with GPS data-logger radio-collars. The collars were to provide information on daily activity patterns, to determine detection probabilities, and to optimise the proposed spacing of aerial baiting transects and the monitoring track network for the eradication. -
Food-Niche Pattern of the Barn Owl (Tyto Alba) in Intensively Cultivated Agricultural Landscape˟

DOI: 10.1515/ orhu-2018-0002 ˟Presented at 1st Hungarian Owl Research Conference held in Pécs on 8th September 2017 Abstract This study investigated the dietary niche of the Barn Owl (Tyto alba) in an intensively farmed landscape, based on pellet samples from 12 nesting pairs containing 25 animal taxa and 1,994 prey items after the breeding sea- son in 2016. Based on land use categories of the buffer area around each nest, three landscape types (agricultural, mo- saic, urban) were considered, to analyse the diet composition and food-niche parameters. Niche breadth was calculat- ed at the local and landscape level. Small mammals were the most frequent in the diet than other prey in each of the landscape types. The Common Vole (Microtus arvalis), considered to be an important agricultural pest was the most numerous prey in all landscape groups. The trophic niche of Barn Owl varied between 0.69 – 0.86 at the local level, and the overall value of niche breadth was significantly higher in the urban than in the other two landscape types. Our results showed that the increase of Common Vole frequency lead to a decrease in niche breadth; significantly negative relationship was detected between these parameters. -

Observations on the Biology of the Powerful Owl Ninox Strenua in Southern Victoria by E.G
VOL. 16 (7) SEPTEMBER 1996 267 AUSTRALIAN BIRD WATCHER 1996, 16, 267-295 Observations on the Biology of the Powerful Owl Ninox strenua in Southern Victoria by E.G. McNABB, P.O. \IJ~~ 408, Emerald, Victoria 3782 . \. Summary A pair of Powerful Owls Ninox strenua was studied at each of two sites near Melbourne, Victoria, for three years (1977-1979) and 15 years (1980-1994 inclusive) respectively, by diurnal and nocturnal observation. Home ranges were.mapped, nest sites characterised and breeding chronology and success monitored. General observations at these and eight other sites, of roosting, courting, nesting, parental and juvenile behaviour, fledgling mortality, hunting, interspecific conflicts, bathing, and camouflage posing, are presented. The regularly used parts of the home ranges of two pairs were each estimated as c. 300 ha, although for one pair this applied only to the breeding season. One pair used seven nest trees in 15 years, commonly two or three times each (range 1-4 times) over consecutive years before changing trees. Nest-switching may have been encouraged by human inspection of hollows. Nest entrances were 8-40 m (mean 22 m) above ground. The owls clearly preferred the larger and older trees (estimated 350-500+ years old), beside permanent creeks rather than seasonal streams, and in gullies or on sheltered aspects rather than ridges. Laying dates were spread over a month from late May, with a peak in mid June. The breeding cycle occupied three months from laying to fledging, of which the nestling period lasted 8-9 weeks. Breeding success was 1.4 young per pair per year and 94% nest success; early nests in gullies were more successful than late nests on slopes. -
Pre–Release Training of Juvenile Little Owls Athene Noctua to Avoid Predation
Animal Biodiversity and Conservation 34.2 (2011) 389 Pre–release training of juvenile little owls Athene noctua to avoid predation R. Alonso, P. Orejas, F. Lopes & C. Sanz Alonso, R., Orejas, P., Lopes, F. & Sanz, C., 2011. Pre–release training of juvenile little owls Athene noctua to avoid predation. Animal Biodiversity and Conservation, 34.2: 389–393. Abstract Pre–release training of juvenile little owls Athene noctua to avoid predation.— Anti–predator training of juvenile little owls was tested in a sample of recovered owls raised in captivity in Brinzal Owl Rescue Center (Madrid, Spain). Mortality caused by predators has been described previously in released individuals. Nine little owls were conditioned during their development to a naturalized goshawk and a large live rat, whose presence was paired to the owl’s alarm call. All nine owls and seven non–trained individuals were then released during the late summer and autumn and radio–tracked for six weeks to test their survival. In total 71.4% of the trained owls survived while only the 33.3% of the untrained group were alive at the end of week six. The only cause of death that was detected was predation. Antipredator training, therefore, seems to be beneficial in maximizing survival after the release of juvenile little owls. Key words: Little owl, Athene noctua, Reintroduction, Release, Survival, Antipredator training.

East Kimberley Impact Assessment Project
East Kimberley Impact Assessment Project HISTORICAL NOTES RELEVANT TO IMPACT STORIES OF THE EAST KIMBERLEY Cathie Clement* East Kimberley Working Paper No. 29 ISBN O 86740 357 8 ISSN 0816...,6323 A Joint Project Of The: Centre for Resource and Environmental Studies Australian National University Australian Institute of Aboriginal Studies Anthropology Department University of Western Australia Academy of the Social Sciences in Australia The aims of the project are as follows: 1. To compile a comprehensive profile of the contemporary social environment of the East Kimberley region utilising both existing information sources and limited fieldwork. 2. Develop and utilise appropriate methodological approaches to social impact assessment within a multi-disciplinary framework. 3. Assess the social impact of major public and private developments of the East Kimberley region's resources (physical, mineral and environmental) on resident Aboriginal communities. Attempt to identify problems/issues which, while possibly dormant at present, are likely to have implications that will affect communities at some stage in the future. 4. Establish a framework to allow the dissemination of research results to Aboriginal communities so as to enable them to develop their own strategies for dealing with social impact issues. 5. To identify in consultation with Governments and regional interests issues and problems which may be susceptible to further research.

From these, we collected a total of 157 owl pellets. Analysis and examination of the pellets revealed 329 prey items. More in-depth investigation determined that 95.1% of the Eastern Grass Owl pellets collected consisted of mammal remains, while the remaining 4.9% were made up of bird remains. Of the various types of mammals consumed, rats made up the highest proportion, with a total of 285 rats, accounting for 86.6%. This was followed by 27 shrews and moles, accounting for 8.2%. Hares and birds were seldom caught and consumed. The findings suggested that rats are the main food source of the Eastern Grass Owl, with the Spinus Country-rat (Rattus losea) comprising the majority with 136 counted (41.3%), followed by the Formosan Mouse (Mus caroli) with 96 counted (29.2%).
