![]() ![]() Of Barking Owls within the Pilliga forests. ![]() Spatial availability of total prey biomass offered a good explanation for the distribution Mammal groups were not significantly different but showed the same positive With prey availability: significantly with the biomass of birds and with flying insect Barking Owls distribution was positively associated Prey items from all prey groups were availableįrom all sampled areas of the Pilliga. Trapping, bat surveys and insect netting. With available prey, as determined by bird counts, spotlight surveys, small mammal The proportions of consumed prey, as determined by pellet analysis, were compared Most prey were native animals in contrast to some other studies. Prey size ranged from 0.3 gram insects to ~800 gram cockatoos and mammals, a Foraging observations improved the understanding of the results.īarking Owls in the Pilliga forests preyed on most species of diurnal and nocturnalīirds, as well as Sugar Gliders, bats and insects, with a few items being taken from the In total, 1546 regurgitated pellets and 315 faecal samples wereĬollected and examined. Ultimately, the collection period spanned 2003 –Ģ009, with prey remains from 19 territories in the Pilliga and one territory in a small forest Pellets, food debris and faecal material). Provided the opportunity to begin a substantial collection of prey remains (regurgitated ![]() Territories over several years and all seasons of the year. This is the first diet study of a Barking Owl population to incorporate data from many The species’ large home ranges and restricted distribution, particularly those that are related I consider a number of hypotheses that could explain In this thesis, I quantify theĭiet of Barking Owls in the Pilliga. Occupy large home-ranges across less than half of the forest. South Wales is the largest known in southern Australia.
