Breeding diets of four raptor species in the Australian tropics
Posted: 26/02/2016The breeding diets of four diurnal raptor species were studied, by analysis of pellets, prey remains, stomach flushes of trapped birds and feeding observations, in the Top End of the Northern Territory and in the Kimberley region (northern Western Australia) in 1988–89. These were the Black-breasted Buzzard Hamirostra melanosternon, Brown Goshawk Accipiter fasciatus, Little Eagle […]
Read MoreDiurnal birds in the Bungawalbin Creek catchment, northern New South Wales, with a focus on spatial and temporal changes in reporting rates of declining woodland birds
Posted: 26/02/2016Birds at 41 sites in grassy dry open sclerophyll (eucalypt) forests and woodlands in eight State Forests in the Bungawalbin Creek catchment, Richmond River District, northern New South Wales, were surveyed across all seasons from February 2004 to July 2006. One hundred and eight diurnal species were detected, including 11 state listed threatened species and […]

Posted: 01/12/2015This paper describes the frequency of Barking Owl Ninox connivens loud (‘barking’) calls over one dry and one wet season in 1981–82 at Kapalga within Kakadu National Park in the Northern Territory, Australia. A single recording site was located on the fringe of the tree-less seasonally inundated black soil floodplain of the South Alligator River […]
Read MoreThe movement and survival of Star Finches Neochmia ruficauda subclarescens in the Wyndham Region of Western Australia
Posted: 01/12/2015This study uses capture-recapture data from four years of mistnetting in the Wyndham district of Western Australia to investigate the movement, longevity and survival probability of the Star Finch Neochmia rufi cauda subclarescens. Results show that Star Finches should be described as locally mobile rather than sedentary; juvenile survival during the study period was low […]
Read MoreA comparative evaluation of transect, point count and two-hectare search methods for bird abundance estimates in dry sclerophyll forest and rainforest
Posted: 01/12/2015Birds were counted with transect, point count and two-hectare search methods at one dry sclerophyll forest site and one subtropical rainforest site in northern New South Wales. Five population density estimators and one reporting rate index were evaluated. True densities were unknown and comparisons focused on variation between methods. Distance sampling line transect and point […]
