DISTRIBUTION AND ABUNDANCE OF WHITE-BELLIED SEA-EAGLES IN SOUTH AUSTRALIA
Posted: 06/08/2021A survey conducted between 1988 and 1994 located 55 occupied territories of White-bellied Sea-Eagle in South Australia. Survey methods included: information from the literature; systematic survey in the Great Australian Bight region, southern Eyre Peninsula and Kangaroo Island; opportunistic survey elsewhere; and contact with other people. Eighteen (33%) of these territories were found on the […]
Read MoreOBSERVATIONS ON COLOUR-BANDED REGENT HONEYEATERS Xanthomyza phrygia
Posted: 06/08/2021Forty-six Regent Honeyeaters were colour-banded between 1991 and 1995. One bird nested at the same site after a probable absence of two years; two pairs re-nested in the same year after fledging young; one bird, banded in April, bred at a site 42 km away in the following spring. Comparison of measurements of birds of […]
Read MoreFORAGING BEHAVIOURAL ECOLOGY OF THE SUPERB LYREBIRD
Posted: 06/08/2021Foraging was investigated in a Superb Lyrebird population in southern Victoria. Soil invertebrate food resources were moderately patchily distributed and the fact that foraging effort and success varied greatly spatially suggested that the birds located patches mainly by trial-and-error. The similarity of the nestling’s diet, the soil invertebrate fauna and probably the adult’s diet, plus […]

Posted: 05/08/2021TIMING AND SUCCESS OF BREEDING IN SUBTROPICAL MASKED LAPWINGS
Posted: 05/08/2021The breeding activities of Masked Lapwings Vanellus miles were studied over two breeding seasons in a subtropical location near Brisbane, Queensland. Breeding parameters including timing, hatching and fledging success are presented. Although most pairs commenced breeding in May-June, renesting following high rates of nest failure (probably due to predation) continued over several months. Clutch size […]

Posted: 05/08/2021CHANGES IN THE ABUNDANCE OF SILVEREYES IN A CENTRAL VICTORIAN VINEYARD DURING THE GRAPE RIPENING PERIOD
Posted: 05/08/2021Population parameters of Silvereyes in Chateau Leamon, a vineyard in central Victoria, were estimated on the basis of capture-recapture methods employed during the grape ripening seasons 1988-1993, using the Jolly-Seber model, the Peterson model and a model of Seber. In the context of low survival rates, results from the Jolly-Seber model were erratic, and as […]
Read MoreTERRITORIAL AND BREEDING BEHAVIOUR OF THE RUFOUS TREECREEPER (Climacteris rufa) IN THE STIRLING RANGES, WESTERN AUSTRALIA
Posted: 05/08/2021A population of colour-banded Rufous Treecreepers Climacteris rufa was studied in wandoo woodland in the Stirling Range National Park, 89 kilometres north of Albany, Western Australia, from June 1990 to January 1994. Five territories were studied and consisted of at least one adult female, one, two or three adult males and one to two juvenile […]
Read MoreDISPERSION, SIZE AND ORIENTATION OF BOWERS OF THE GREAT BOWERBIRD Chlamydera nuchalis (PTILONORHYNCHIDAE) IN TOWNSVILLE CITY, TROPICAL QUEENSLAND
Posted: 05/08/2021Eighty active Great Bowerbird Chlamydera nuchalis bowers were examined of which 54 were measured and 61 plotted in the suburbs of Townsville City, tropical E. Queensland, where the species was reported by earlier authors to be absent or uncommon. The average number of years a bower was known to have been in use at 54 […]
