A comparative evaluation of transect, point count and two-hectare search methods for bird abundance estimates in dry sclerophyll forest and rainforest

Posted: 02/03/2015
Category: Volume 37
Author(s): Stephen Totterman

Birds 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 […]

Footedness in the Glossy Black Cockatoo: Some observations and a review of the literatute with a note on the husking of Allocasuarina cones by this species.

Author(s): David Magrath

A survey of the literature on the use of a particular foot to hold food by Australian parrots suggests that most of the few species that have been studied are left-footed. Most, but not all, Glossy Black- Cockatoos Calyptorhynchus lathami observed have been left-footed. I present some field observations on the footedness of this species; […]

A comparison of species counts and density estimates derived from area searches, line transects and point counts in the Jarrah forest of south-western Australia.

Posted: 01/01/2015
Category: Issue 2
Author(s): Michael Craig

No studies have examined differences between census methods for birds in south-western Australian forests, yet unique features of south-western forests may be responsible for differences from those recorded in studies conducted elsewhere. Differences in the number of bird species recorded and densities estimated by area searches, line transects and point counts in jarrah forests of […]

Diet of 25 sympatric raptors at Kapalga, Northern Territory, Australia 1979–89, with data on prey availability

Posted: 12/12/2014
Author(s): Laurie Corbett, Tony Hertog, Johnny Estbergs

This study describes prey availability and the diet of 25 sympatric diurnal and nocturnal raptors over 11 years 1979–89 in tropical Australia, at Kapalga in Kakadu National Park. Rainfall is seasonal: most falls from January to early March, resulting in pronounced annual wet and dry seasons. The major habitats include tidal rivers, seasonally inundated floodplains, […]

Breeding ecology of Welcome Swallows Hirundo neoxena in the Yarra Valley, Victoria: the nestling stage

Posted: 12/12/2014
Author(s): Alan Lill

Breeding ecology studies encompassing multiple seasons, sites and breeding attempts help in determining which aspects of a species’ breeding ecology are widespread, which vary temporally and spatially, and the reasons for such variation. The nestling stage of Welcome Swallows Hirundo neoxena breeding in eleven sites less than or equal to 12 kilometres apart in the […]
