A population of Sulphur-crested Cockatoo Cacatua galerita at Ashfield, New South Wales, was observed over a four year period. The birds were intentionally habituated to human observers and contact with humans was positively reinforced. The habituation process allowed behaviour patterns to be observed at distances of 0.5-3 m which is closer than other studies on […]
Read MoreThirty-two single-stage transmitters were attached to ten species of waders as part of a study on nocturnal habitat use. Three variations of a method used previously to attach transmitters to waders were compared. The aim of the comparison was to see if less disruptive variations of the standard attachment technique could provide similar retention times. […]
Read MoreThe breeding activities of Wedge-tailed Shearwaters at Raine Island, in the far northern section of the Great Barrier Reef, have not been quantified to date. In December 1995, 58 per cent of burrows inspected with a ‘burrowscope’ were occupied, 52 per cent with incubation or a chick, so approximately half of the estimated 3 661 […]
Read MoreThe long-billed corella causes extensive damage to crops in western Victoria. In an attempt to deter birds from vulnerable crops an appropriate bait is being sought for use in field trials of a chemical deterrent. Food preference was examined in captivity to determine bait acceptability in free-choice and no-choice trials. Corellas (n = 10) were […]
Read MoreThe common practice of including a green dye in baits used for pest animal control is thought to provide some protection to non-target birds because general avoidance of green coloured foods by some bird species has been documented. Captive Long-billed Corellas Cacatua tenuirostris offered a choice between green-dyed and plain whole oats showed a preference […]
